Hey there! :)

y + 9 = 9 ; solve for y.

To solve for y, we must get y onto its own side of the equal sign. So, our first step should be to subtract 9 from both sides.

y + 9 - 9 = 9 - 9

Simplify.

y = 0

To check if y is truly equal to 0, let's plug in 0 for y in our initial equation.

y + 9 = 9 --> 0 + 9 = 9

9 = 9

Therefore, y = 0.

y + 9 = 9

Subtract 9 to both sides to isolate the 9 on the y. Whatever you do on one side you have to do it to the other side, your answer should be

y + 9 = 9

- 9 - 9

y = 0

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

Nat2105 [25]

Answer:

Step-by-step explanation:

First choose two points on the line,

Let the points are A and B.

From point A to B we are moving downwards by (5 - 1 = 4 units)

Therefore, Rise = -4

Horizontal distance between A and B = 2 units

Therefore, Run = 2

Since, slope of a line = $\frac{\text{Rise}}{\text{Run}}$

Slope = $\frac{-4}{2}$

= -2

Solve for z. 8z − 4 = 7z

aleksandr82 [10.1K]

8z − 4 = 7z

move 8z to the other side

sign changes from +8z to -8z

8z-8z-4=7z-8z

-4= 7z-8z

-4= -z

mutiply both sides by -1 to get +z

(-4)(-1)= (-z)(-1)

Answer:

z= 4

Peter works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. Last month, he worked

Romashka-Z-Leto [24]

Answer:

$10,318.62

Step-by-step explanation:

We have been given that works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. If he works over 40 hours during any week, he earns double his hourly wage.

Peter's hourly charges during 1st and 2nd week would be $33.19 and hourly charges during 3rd and 4th week would be 2 times $33.19.

First of all, we will find total hourly income as:

$\text{Total hourly income}=\$33.19(30+40)+2\times \$33.19(49+55)$

$\text{Total hourly income}=\$33.19(70)+\$66.38(104)$

$\text{Total hourly income}=\$2323.3+\$6903.52$

$\text{Total hourly income}=\$9226.82$

Now, we will find income from commission on sales as:

$\text{Income from commission on sales}=\frac{5.3}{100}(4500+5500+3800+6800)$

$\text{Income from commission on sales}=0.053(20600)$

$\text{Income from commission on sales}=1091.8$

Peter's total earnings is the last month: $\$9226.82+\$1091.8=\$10,318.62$

Therefore, Peter's total earnings in last month was $10,318.62.
