What’s the question, sorry

You might be interested in

Kelli and Karl each have a job. Kelli earns $20 an hour. She also receives a $100 weekly bonus.

ad-work [718]

Equation for Kelli's earning = 20x + 100
Equation for Karl's earning = 25x + 50

Now, 20x +100 = 25x +50
25x-20x = 100-50
5x = 50
x = 10

So, your answer is 10 hours.

Hope this helps!

Calculate the slope of the line for Graph C.

salantis [7]

Answer:

$- \frac{5}{4}$

Step-by-step explanation:

Use the slope form:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

m = slope

Let:

$(x_1 , y_1) = (-2 , -8)\\(x_2 , y_2) = (-6 , -3)$

Plug in the corresponding numbers to the corresponding variables, and solve:

$m = \frac{-3 - (-8)}{-6 - (-2)} = \frac{-3 + 8}{-6 + 2} = \frac{5}{-4} = -\frac{5}{4}$

$- \frac{5}{4}$ is your answer.
