Hey there! :D

y=2x-9

We can plug that in as y, since y is equal to 2x-9.

5x-3(2x-9)= 23

Distribute.

5x-6x+27= 23

-1x+27=23

Subtract 27 on both sides.

-1x=-4

Divide both sides by -1.

x=4

Now, plug that in for y.

y=2(4)-9

y=8-9

y=-1

(4,-1) <== solution

I hope this helps!

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.

Nitella [24]

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

$\mathbf{C(t) = 87t + 32}$

A linear function is represented as:

$\mathbf{C(t) = mt + b}$

Where:

m represents the slope or the unit rate.

So, by comparison:

$\mathbf{m = 87}$

This means that 87 represents the slope and the cost per tire purchased

This is #5 <br> Algebra-Find the value for x<br> I know it’s 11 but how do I get there.

Sergeeva-Olga [200]

Answer:

x = 11

Step-by-step explanation:

the line x + 5 is a mid segment of the triangle and thus is half the length of 3x - 1, that is

x + 5 = $\frac{1}{2}$ (3x - 1)

multiply both sides by 2 to eliminate the fraction

2x + 10 = 3x - 1 ( subtract 3x from both sides )

- x + 10 = - 1 ( subtract 10 from both sides )

- x = - 11 ( multiply both sides by - 1 )

x = 11
