The scatter plot shows the wages of employees.

y + 6x + 120

1. If an employee earns $570, what is the
expected number of copiers sold?

(1) The expected number of copies sold is 75

(2) The expected wage is $720

Explanation:

From the graph, we can see that x represents the number of copiers sold.

y represents the wages.

The equation of the graph is

(1) Given that an employee earn $570.

We need to determine the number of copiers sold.

Let us substitute in the equation , we get,

Thus, the number of copiers sold is 75

(2) Given that if an employee sells 100 copiers, we need to determine the expected wage.

Let us substitute in the equation , we get,

Thus, the expected wage is $720

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

x equals 1
