3x +y = 14
Rewrite equation in slope intercept form solve for y
To rewrite the equation in slope-intercept form and solve for y, we isolate y on one side of the equation by subtracting 3x from both sides. The resulting equation is y = -3x + 14.
Explanation:To rewrite the equation in slope-intercept form and solve for y, we need to isolate y on one side of the equation.
Given the equation 3x + y = 14, we can start by subtracting 3x from both sides to get y alone.
The equation becomes y = -3x + 14, which is now in slope-intercept form (y = mx + b) where the slope (m) is -3 and the y-intercept (b) is 14.

A fish tank is in the shape of a right circular cylinder with a height of 20 feet and a volume of 320 pi cubic feet. What is the radius, in feet, of the fish tank?
A. 16
B. 10
C. 8
D. 4
Answer:
4 feet
Step-by-step explanation:
From the question, we are given;
Height of the cylinder as 20 ft Volume of the cylinder as 320 piWe are required to find the radius of the cylinder fish tank;
We need to know that the volume of a cylinder is given by;Volume = pi × r² × h
Rearranging the formula;
r² = V ÷ pi × h
Therefore;
r² = 320 pi ÷ (pi × 20 ft)
= 16
Thus;
r = √16
= 4 ft
Therefore, the radius of the fish tank is 4 feet.

A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries 12.5, 2.5, 0.5, 0.1, 0.02.
Which exponential function is represented by the table?
f(x) = 0.2(0.5x)
f(x) = 0.5(5x)
f(x) = 0.5(0.2x)
f(x) = 0.2(0.2x)
Answer:
[tex]f(x)=0.5\cdot (0.2)^x[/tex]
Step-by-step explanation:
Given the table
[tex]\begin{array}{cc}x&f(x)\\ \\-2&12.5\\ -1&2.5\\0&0.5\\1&0.1\\2&0.02\end{array}[/tex]
The exponential function can be written [tex]f(x)=a\cdot b^x.[/tex] To find [tex]a[/tex] and [tex]b,[/tex] substitute some values:
When [tex]x=0,\ f(x)=0.5,[/tex] then

Put an S in the grid below to show the number of sparrows and a C to show the number of cardinals. There may be extra squares. (See attachment)
Answer:
Please find the grid of Sparrows and Cardinals below.
Step-by-step explanation:
Ratio 3:1 of Sparrows to Cardinals
There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder
Let's build the grid for sparrows and cardinals, this way:
Sparrows = 7 - 8 - 9 - 10 - 11
Cardinals = 2 - 3 - 3 - 3 - 4
For calculating the number of cardinals we use the ratio 3:1 and round the number of cardinals to the next whole number.
Number of sparrows 7 to 11
Number of cardinals 2 to 4
DOES IT MAKE SENSE?
Decide whether each of the following statements makes sense (or is clearly

housing costs (rent and home mortgage payments).
13)A popular local restaurant serves 5 million dinners each year.
14)The CEO of the company earned more money last year than
the company's 500 lowest-paid employees combined.
This answer evaluates each statement for its potential truthfulness, noting that while each could arguably be correct, they might also be inaccurate in certain contexts.
Explanation:It's tricky to definitively state whether these statements are true or false without further context, as they contain details that could conceivably be true but may also potentially be inaccurate.
I read a book that had 10 words in it. This could be possible, especially for children's books or minimalist concept books. I've seen about 1050 commercials on TV. This might be true or not, considering that a person who watches television regularly could have seen this number of commercials. I work in an office building that is 300 feet high. This statement is plausible, given there are many buildings of this height. In total, Americans spend about a billion dollars per year on housing costs (rent and home mortgage payments). This is probably true since the American housing market is extensive. A popular local restaurant serves 5 million dinners each year. This is a high number, but it could be true for a very popular or large restaurant. The CEO of the company earned more money last year than the company's 500 lowest-paid employees combined. Sadly, this could be true given the substantial wage gaps that can exist in companies.

A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2
pounds of almonds, the total cost is $16 . For 3 pounds of jelly beans and 5 pounds of almonds, the total cost is $13. Find the cost for each pound of jelly beans and each pound of almonds.
The cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25
Solution:
Let the cost of each pound of jelly beans is "a"
Let the cost of each pound of almond is "b"
For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $16
Therefore, we frame a equation as:
6 pounds of jelly beans x cost of each pound of jelly beans + 2 pounds of almonds x cost of each pound of almond = 16
[tex]6 \times a + 2 \times b = 16[/tex]
6a + 2b = 16 --------- eqn 1
For 3 pounds of jelly beans and 5 pounds of almonds, the total cost is $13
Therefore, we frame a equation as:
3 pounds of jelly beans x cost of each pound of jelly beans + 5 pounds of almonds x cost of each pound of almond = 13
[tex]3 \times a + 5 \times b = 13[/tex]
3a + 5b = 13 ----------- eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 2 with 2
6a + 10b = 26 --------- eqn 3
Subtract eqn 1 from eqn 3
6a + 10b = 26
6a + 2b = 16
( - ) -------------------------
8b = 10
[tex]b = \frac{10}{8} = 1.25[/tex]
b = 1.25Substitute b = 1.25 in eqn 1
6a + 2(1.25) = 16
6a + 2.5 = 16
6a = 13.5
a = 2.25Thus cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25

For his coffee shop, Abdul wants to make a mocha-java blend that will sell for $18/kg. The mocha coffee beans sell for $20/kg, and the java coffee beans sell for $15/kg. How many kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend?
30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg
Solution:
Let "x" be the kilogram of mocha coffee beans
Let "y" be the kilogram of java coffee beans
Cost of 1 kg of mocha coffee bean = $ 20
Cost of 1 kg of java coffee bean = $ 15
Kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend
Cost of 1 kg of mocha java blend = $ 18
From given information,
Mocha coffee beans and java coffee beans are mixed to get 50 kg of blend
Therefore,
[tex]x + y = 50 ------------ eqn 1[/tex]
Abdul wants to make a mocha-java blend that will sell for $18/kg
Therefore, we frame a equation as:
(kilogram of mocha coffee beans) x (Cost of 1 kg of mocha coffee bean) + (kilogram of java coffee beans) x (Cost of 1 kg of java coffee bean) = Cost of 1 kg of mocha java blend x 50 kg
Thus we get,
[tex]x \times 20 + y \times 15 = 18 \times 50\\\\20x+15y = 900 ------------ eqn 2[/tex]
Let us solve eqn 1 and eqn 2
From eqn 1,
x = 50 - y -------- eqn 3
Substitute eqn 3 in eqn 2
20(50 - y) + 15y = 900
1000 - 20y + 15y = 900
5y = 100
y = 20Substitute y = 20 in eqn 3
x = 50 - 20
x = 30Thus 30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg
We need to set and solve a system of equations, with the variables representing the weights of mocha and java coffee in the blend. Solving the system yields the number of kilograms needed.
Explanation:To solve your problem, Abdul, we will use the concept of weighted averages. We'll need two equations. Let's denote the weight of the mocha coffee in the mix by x kg and the weight of java coffee by y kg. From the problem's requirements, we get these two equations:
x + y = 5020x + 15y = 18*50.Now, the goal is to solve this system of equations. You can do that by, for example, substituting x = 50 - y in the second equation and solving for y. Then, substitute y's value back into the first equation to get x.
The solution to this system will give you the weights of mocha and java coffee beans needed to make your desired blend.

Part A: Write an equation of a line that is perpendicular to the line y = 2/3x + 5 and passes through the point (4, 0).
Part B: Explain how you determine the equation in 3-4 sentences using at least 6 of the words below.
Slope
y-intercept
x-intercept
perpendicular
opposite
reciprocal
substituted/substitution
slope-intercept
ordered pair
Step-by-step explanation:
First you need to make a line perpendicular to y=2/3x+5. To do that you have to know that, if we use y=ax+b, a1*a2=-1. That is if a1 and a2 are perpendicular. So we get 2/3*a2=-1. -1/ 2/3=a2. a2=-1.5. We get y=-1.5x+b. Fill in (4,0) on y=-1.5x+b abd we get 0=-1.5(4)+b. b=6
Answer:
y = (-3/2)x - 6
Step-by-step explanation:
slope of the line y= 2/3x + 5
slope = 2/3
for two perpendicular lines
slope1*slope2 = -1
so, slope2 = (-1)*(3/2) = -3/2
hence for it to pass (4,0)
slope2=(y2 - y1)/(x2 - x1)
-3/2 = (y - 0)/(x - 4)
cross multiplying
-3x -12 = 2y
the equation of the line is
y = (-3/2)x - 6

Find the coordinates of the midpoint of the line segment with the endpoints C(1,0) and D(5,4)
Answer:
(3, 2 )
Step-by-step explanation:
Given the endpoints are (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) [
Here (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (5, 4), thus
midpoint = [0.5(1 + 5), 0.5(0 + 4) ] = (0.5(6), 0.5(4)) = (3, 2 )
Answer:
(3,2)
Step-by-step explanation:
To find a midpoint of two given points, we can use the formula:
[tex](x_{m} ,y_{m} ) = (\frac{x_{1} +x_{2} }{2} , \frac { y_{1} +y_{2}}{2})[/tex]
(i.e. we just take the average of the x coordinates, and similarly, the average of the y coordinates).
so we get:
midpoint = ( (1+5)/2, (0+4)/2 )
= (3, 2)
(-5, -5), 6x - y = 1
Write an equation of the lines that passes through the given point and is parallel to the given line.
Answer:
Step-by-step explanation:
6x - y = 1
6x - 1 = y.....rearrange
y = 6x - 1......slope is 6. A parallel line will have the same slope.
y = mx + b
slope(m) = 6
(-5,-5)...x = -5 and y = -5
now we sub and find b, the y int
-5 = 6(-5) + b
-5 = -30 + b
-5 + 30 = b
25 = b

Raphael runs every day for several weeks. He runs for 35 days in a row. How many weeks did he run?
Answer:
5 weeks
Step-by-step explanation:
There are 7 days in a week.
5 weeks * 7 days = 35 days.
Raphael ran for a total of 5 weeks.
To calculate how many weeks Raphael ran, we need to divide the number of days he ran by the number of days in a week.
Raphael ran for 35 days.
Since there are 7 days in a week, we divide 35 by 7:
35 days / 7 days per week = 5 weeks
Therefore, Raphael ran for 5 weeks.
