Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in a standard form.

Convert to the slope-intercept form:

[tex]2x-y=-1[/tex]         add y to both sides

[tex]2x-y+y=-1+y[/tex]

[tex]2x=-1+y[/tex]            add 1 to both sides

[tex]2x+1=-1+1+y[/tex]

[tex]2x+1=y\to y=2x+1[/tex]

The slope intercept form of the given equation is y = 2x+1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

(ii) 3x + 5 = 15

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given that, an equation of a line, 2x-y = -1, we need to convert this into slope intercept form,

The standard form of the equation of a line in slope intercept form, is given by :

y = mx+c

Where, m = slope of the line, c is the y-intercept,

So, the given equation is 2x-y = -1,

Add y both the side,

2x-y+y = -1+y

2x = -1+y

Add 1 in both sides,

2x+1 = y+1-1

y = 2x+1

Hence, the slope intercept form of the given equation is y = 2x+1

Explaining how to find the number of solutions in a system of linear equations.

Explanation:

The given equations are:

y = x - 3

4x - 10y = 6

To find the number of solutions, we can solve these equations simultaneously.

Substitute y = x - 3 into the second equation and solve for x to find the value of y. If the solution leads to a valid pair of x and y that satisfies both equations, then there is one unique solution, otherwise there are no solutions.

Answer:

The amount of sales in order to meet her goal must be greater than or equal to $20,000

Step-by-step explanation:

Let

x----> represent the amount of sales Liz will need

we know that

The amount of sales for the month multiplied by the commission rate as a decimal plus the fixed amount must be greater than or equal to $2,800 each month

so

The inequality that represent this situation is

[tex]0.03x+2,200\geq 2,800[/tex]

solve for x

subtract 2,200 both sides

[tex]0.03x \geq 2,800-2,200[/tex]

[tex]0.03x \geq 600[/tex]

divide by 0.03 both sides

[tex]x \geq \$20,000[/tex]

The amount of sales in order to meet her goal must be greater than or equal to $20,000

The question involves solving simultaneous linear equations, a high school level topic in mathematics. Methods like substitution or elimination can be used to find the values of the variables.

The student's question involves solving simultaneous linear equations, which is a topic in mathematics. To solve the given system of equations, one can use methods such as substitution, elimination, or matrix operations like determinants. The elimination method can be particularly efficient. For example, you can multiply the first equation by a number that will allow the x or y terms to cancel out when added or subtracted from the second equation. After simplifying, you're left with one equation in one unknown, which can be easily solved. Then, back-substitute the known value into one of the original equations to solve for the other variable.

Given the equations 3x + 7y = -5 and 8x + 9y = 6, we may choose to multiply the first equation by 3 and the second by 7 (to eliminate the x terms) or to multiply the first equation by 8 and the second by 3 (to eliminate the y terms). Once one variable is eliminated, we solve for the other and use it to find the value of the remaining variable.

Answer:

Step-by-step explanation: You would do 5x+20+x+40=180

Then you would add 5x and x together and you would also add 20 and 40 together and then you get: 6x+60=180

You would then subtract 180-60 and then you should get 6x=120 and the you would divide from both sides and you should get x=20 you would then plug it into both angles So 5(20)+20 and you should get 120 for the left angle and then you would do the next angle which would be 20+40=60 for the right angle

Short version:

5x+20+x+40=180

6x+60=180

6x=120

The value of x is 3.5.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Right triangle with vertices labeled as A, B, and C.

Side C B is the base and the top vertex is A.

Side A B contains a midpoint D.

A line segment drawn from C to D bisects angle A C B into two parts labeled as A C D and B C D.

Side A C= 5.

Base C B = 6.

Line Segment A D = x.

Segment B D=4.2.

4.2/6=x/5

Apply cross multiplication

4.2×5=6x

21=6x

Divide both sides by 6

x=3.5

Hence, the value of x is 3.5.

Answer:

Cost of one glove pair is $ 8.50 and the cost of one hat is $6.50

Step-by-step explanation:

Let g represents the cost of one gloves pair

h represents the cost of one hat

Then

Cody brought two pairs of gloves and four hats for $43.00

This can be written as

2g + 4h = 43-------------------(1)

Tori bought two pairs of gloves and two hats for 30.00

This can be written as

2g + 2h = 30------------------(2)

Subtracting (2) from (1)

2g + 4h = 43

2g + 2h = 30

(-)

--------------------------

0g + 2h = 13

------------------------------------

2h =13

h = 13 / 2

h = 6.5---------------------(3)

Substituting (3) in (2)

2g + 2(6.5) = 30

2g + 13 = 30

2g = 17

g = 17 / 2

g = 8.5

So one hat is $6.50 and one pair of gloves is $8.50.

Solved given expression for x using the change of base formula log base b of y equals log y over log b is 4.459

Answer: Option D

Step-by-step explanation:

Given Expression:

             [tex]2^{x-1}=11[/tex]

To solve this, first convert the exponential form into log form

If  [tex]a^{x}=b[/tex] then [tex]\log _{a}(b)=x[/tex]

So, when comparing the given expression with above,  a = 2, x = x – 1 and b = 11 .

            [tex]2^{x-1}=11[/tex] become [tex]\log _{2}(11)=x-1[/tex]

Now, apply change of base formula to remove base 3

             [tex]\log _{a}(y)=\frac{\log y}{\log a}[/tex]

Hence,

            [tex]\log _{2}(11)=\frac{\log 11}{\log 2}[/tex]

Substitute [tex]\log _{2}(11)=x-1[/tex] in above expression, we get

           [tex]\frac{\log 11}{\log 2}=x-1[/tex]

           [tex]\frac{1.0414}{0.301}=x-1[/tex]

           x – 1 = 3.459

          x = 3.459 + 1 = 4.459

Final answer:

To solve the equation 2^(x - 1) = 11 for x, one can use the change of base formula by taking the logarithm of both sides, rewriting the equation using logarithm properties, isolating x, and then simply calculating using a calculator, which results in x ≈ 1.289.

Explanation:

To solve 2(x − 1) = 11 for x using the change of base formula, take the logarithm of both sides of the equation and use the formula logb(y) = log(y) / log(b), where y is the number we want to take the logarithm of and b is the base of the logarithm.

Let's start the process:

Now, calculate the right side of the equation using a calculator:

Hence, the correct answer is B) 1.289.

Step-by-step explanation:

=============================================

Work Shown:

f(x) = 6x + b

f(5) = 6(5) + b .... replace every x with 5

f(5) = 30 + b

1 = 30 + b ..... replace f(5) with 1, since f(5) = 1 was given.

1-30 = 30 + b - 30 .... subtract 30 from both sides

-29 = b

b = -29

-----------

The function f(x) = 6x+b turns into f(x) = 6x+(-29) which is equivalent to f(x) = 6x-29

Plugging in x = 5 leads to

f(x) = 6x-29

f(5) = 6(5) - 29

f(5) = 30 - 29

f(5) = 1

So we have confirmed the answer.

Answer:
