Answer:

The graph is plotted below.

One ordered pair as solution is (0, 0).

Step-by-step explanation:

Given:

The inequality is given as:

[tex]y\geq x-5[/tex]

In order to plot it, we first replace '≥' by '=' sign. This gives,

[tex]y = x-5[/tex]

Now, we plot the above line. For that, we need the x and y intercepts.

At x-intercept, y = 0. So,

[tex]0=x-5\\x=5[/tex]

The point is (5, 0)

At y-intercept, x = 0. So,

[tex]y=0-5\\y=-5[/tex]

The point is (0, -5)

Now, plot these two points and draw a line passing through these two points. The graph is shown below.

Now, replace '=' by '≥' sign. Since, 'y' is greater than equal to 'x - 5'. So, the solution region is above the given including the values on the line.

Therefore, any ordered pair in the solution region is a solution of the given inequality. From the graph, one such ordered pair is (0, 0).

This can be verified from the inequality also.

[tex]0\geq 0-5\\0\geq -5(True)[/tex]

So, one ordered pair is (0, 0).

Answer: 7c ≤ 63

Ivan will buy at most 9 pounds of candy, which means that multiplying 9 by 7, the cost of the candy, will get your answer: 63. Plug these values into an inequality with a less than or equal to sign (≤) facing away from 63 and you're done!

The possible amounts Ivan will spend on candy can be represented as c ≤ 7.

Let's denote the amount Ivan will spend on candy as c. The cost of candy is $7 per pound, and Ivan will buy at most 9 pounds of candy. Therefore, the maximum amount he could spend on candy is 9 pounds multiplied by $7 per pound, which is 9c ≤ 63.

Since we are looking for possible amounts, we can rewrite this inequality as c ≤ 63/9, which simplifies to c ≤ 7.

So, the possible amounts Ivan will spend on candy are values less than or equal to $7.

The explicit formula for the arithmetic sequence is [tex]a_n = 9 - 6n[/tex]

Solution:

Given that the arithmetic sequence is:

3, -3, -9, -15, -21, ...

To find: Explicit formula for the arithmetic sequence

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

Where [tex]a_n[/tex] is nth term of sequence

n is the term's location

[tex]a_1[/tex] is the first term of sequence

d is the common difference between terms

In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.

In the given sequence:

3, -3, -9, -15, -21, ...

[tex]a_1 = \text{ first term } = 3[/tex]

d = difference between any two terms in sequence

[tex]d = a_2 - a_1[/tex]

d = -3 - (3) = -6

Substituting the values in above formula,

[tex]a_n = 3 + (n - 1)(-6)\\\\a_n = 3 -6n + 6\\\\a_n = 9 - 6n[/tex]

Answer:

Mutually exclusive,

[tex]P(\text{Lemon-lime or orange})=\frac{2}{3}[/tex]

Step-by-step explanation:

Please consider the complete question:

Determine if the scenario involves mutually exclusive or overlapping events. Then find the  probability.

A cooler contains twelve bottles of sports  drink: four lemon-lime flavored, four  orange flavored, and four fruit-punch  flavored. You randomly grab a bottle. It  is a lemon-lime or an orange.

Let us find probability of finding one lemon lime drink.

[tex]P(\text{Lemon-lime})=\frac{\text{Number of lemon lime drinks}}{\text{Total drinks}}[/tex]

[tex]P(\text{Lemon-lime})=\frac{4}{12}[/tex]

[tex]P(\text{Lemon-lime})=\frac{1}{3}[/tex]

Let us find probability of finding one orange drink.

[tex]P(\text{Orange})=\frac{\text{Number of orange drinks}}{\text{Total drinks}}[/tex]

[tex]P(\text{Orange})=\frac{4}{12}[/tex]

[tex]P(\text{Orange})=\frac{1}{3}[/tex]

Since probability of choosing a lemon lime doesn't effect probability of choosing orange drink, therefore, both events are mutually exclusive.

We know that probability of two mutually exclusive events is equal to the sum of both probabilities.

[tex]P(\text{Lemon-lime or orange})=P(\text{Lemon-lime})+P(\text{Orange})[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{1}{3}+\frac{1}{3}[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{1+1}{3}[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{2}{3}[/tex]

Therefore, the probability of choosing a lemon lime or orange is [tex]\frac{2}{3}[/tex].

To find the product for 2(2n + 3), use the distributive property to multiply 2 with each term inside the parentheses, resulting in 4n + 6.

The question asks to find the product for 2(2n + 3). To solve this, we need to use the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. Applying this rule to the given expression, we multiply 2 with each term inside the parentheses.

First, multiply 2 by 2n to get 4n. Next, multiply 2 by 3 to get 6. Therefore, the expression simplifies to 4n + 6.

We have successfully used the distributive property to find that the product of 2(2n + 3) is 4n + 6.

[tex]-6y-18=9y-51[/tex]

Adding [tex]6y[/tex] both sides.

[tex]-6y+6y-18=9y+6y-51[/tex]

[tex]-18=15y-51[/tex]

Adding 51 both sides.

[tex]-18+51=15y-51+51[/tex]

[tex]33=15y[/tex]

Dividing both sides by 15.

Answer:

The maximum value of function is 81 .

Step-by-step explanation:

Given function as :

y = 4 (x + 7) (2 - x)

Now, The function can be written as

y = 4 (2 x - x² + 14 - 7 x)

y = 4 ( - x² - 5 x + 14)

y = - 4 x² - 20 x + 56

Now, For maximum value of function , differentiation of y with respect to x

[tex]\frac{\partial y}{\partial x}[/tex] = 0

Or, [tex]\frac{\partial ( - 4x^{2} - 20 x +56)}{\partial x}[/tex] = 0

Or, - 8 x - 20 = 0

Or, - 8 x = 20

∴  x = [tex]\dfrac{-20}{8}[/tex]

i.e  x = [tex]\dfrac{-5}{2}[/tex]

Now, Putting the value of x in the given equation

y = - 4 ( [tex]\dfrac{-5}{2}[/tex])² - 20 ( [tex]\dfrac{-5}{2}[/tex]) + 56

Or, y = - 4 ([tex]\dfrac{25}{4}[/tex]) + 50 + 56

Or, y = - 25 + 50 + 56

∴    y = 81

So, The maximum value of function is 81

Hence,The maximum value of function is 81 . Answer

Answer:

The items are classified as M1, M2, or neither based on their liquidity and spendability. A line of credit and traveler's checks are neither M1 nor M2 as they are not actual money. Physical currency and money in a checking account are classified as M1, while money in a money market account is classified as M2.

M1 refers to the narrowest definition of the money supply, which includes only the most liquid forms of money that can be easily spent. M2 is a broader measure of the money supply and includes M1 as well as other less liquid forms of money. Neither refers to items that do not fit into either M1 or M2.

a. Your $5,000 line of credit on your Bank of America card is neither in M1 nor M2 as it is not actual money but a credit limit.

b. $50 dollars' worth of traveler's checks you have not used yet is neither in M1 nor M2 as they need to be exchanged for cash before they can be spent.

c. $1 in quarters in your pocket is in M1 as it is physical currency that can be spent.

d. $1200 in your checking account is in M1 as it is a liquid form of money that can be spent.

e. $2000 you have in a money market account is in M2 as it is a less liquid form of money that can be accessed but may have restrictions or penalties for withdrawal.

Step-by-step explanation:

Let x be the pens and y be the pencils

Given:

Brian purchased pens for 75 cents each and pencils for 40 cents each he bought total of 22 writing utensils for $11.95.

Total pens and pencils is 22

So, [tex]x+y=22[/tex]----------------(1)

And he bought all utensils for $11.95. and each pen for 75 cents and pencils for 40 cents.

[tex]0.75x+0.40y=11.95[/tex]------------(2)

solve equation 1 and equation 2 for x and y.

From equation 1.

[tex]x+y=22[/tex]

[tex]y=22-x[/tex]----------------(3)

put y value in equation 2.

[tex]0.75x+0.4(22-x)=11.95[/tex]

[tex]0.75x+0.4\times 22-0.4x=11.95[/tex]

[tex]0.75x+8.8-0.4x=11.95[/tex]

[tex]0.75x-0.4x=11.95-8.8[/tex]

[tex]0.35x=3.15[/tex]

[tex]x=\frac{3.15}{0.35}[/tex]

[tex]x=9[/tex]

Now substitute x value in equation 3.

[tex]y=22-9[/tex]

[tex]y=13[/tex]

So, he buy 13 pencils.

The expression for the total cost of bats and gloves is b*x + 5*y. To find the total cost when three bats are bought, you need to know the costs of a bat (x) and a glove (y), and substitute those into the expression.

Assume that the cost of a baseball bat is 'x' dollars and each glove costs 'y' dollars. The total cost can be calculated by making 'b' the number of bats and adding the cost of 5 gloves. Therefore, the expression representing the total cost is b*x + 5*y.

Now, if the coach bought 3 bats, and we're given the costs for a bat and a glove, we can substitute '3' for 'b', 'x' for the cost of a bat, and 'y' for the cost of a glove.

For example, if a bat is $50 (x=50) and a glove is $20 (y=20), the total cost would be: 3*50 + 5*20 = 250 dollars.

https://brainly.com/question/34192827

#SPJ2

Final answer:

The expression for total cost of baseball bats and gloves is 'b times the number of bats plus 5 times the cost of a glove', where 'b' represents the cost of a bat. In the bat and ball problem, if a bat costs $1 more than the ball and together they cost $1.10, the ball costs $0.05. For three bats, the total cost is $3.15.

Explanation:

The question posed is a classic algebra problem from mathematics often used to illustrate a common cognitive error. To write an expression for the total cost of the baseball bats and gloves, let the cost of each bat be represented by 'b' and assume each glove has a fixed cost 'g'. The expression is then b times the number of bats plus 5 times the cost of a glove. However, we require additional information regarding the cost of individual gloves to complete this expression.

Turning to the bat and ball problem, if a bat and ball together cost $1.10, and the bat costs $1 more than the ball, we can set up the following equations where 'x' is the cost of the ball:

x + (x + $1) = $1.10

2x + $1 = $1.10

2x = $1.10 - $1.00

2x = $0.10

x = $0.05

Thus, the ball costs $0.05 and the bat costs $1.05. Finding the cost of three bats, we simply multiply $1.05 by 3 to get $3.15.

Answer:

1. f(2) = 6

2. Slope, m = [tex]$ \frac{7}{2} $[/tex]

Step-by-step explanation:

Problem 1:

Given f(x) = |3x|

To find f(2), substitute x = 2.

⇒ f(2) = |3(2)|

= |6|

= 6

Problem 2:

The given equation is: 2y = 7x + 8

The general equation of the line is: y = mx + c, where m is the slope of the line.

Therefore, we reduce the given equation to the general form of the line.

Dividing the given equation by 2, we get:

y = [tex]$ \frac{7}{2}x + \frac{8}{2} $[/tex]

[tex]$ \implies y = \frac{7}{2}x + 4 $[/tex]

Thus, slope, m = [tex]$ \frac{7}{2} $[/tex] which is the answer.
