Heyo! Reviving this question since I know the answer.

Answer:

x = 6

Step-by-step explanation:

7 + 5(x - 3) = 22

7 + 5x - 15 = 22

7 + 5x = 37

5x = 30

x = 6

Answer:

A. y=-\dfrac{8}{7}x-\dfrac{18}{7}

Step-by-step explanation:

Let y=mx+b be the equation of the perpendicular line.

Two perpendicular lines have slopes with product equal to -1. The slope of the given line is \frac{7}{8} Hence,

\dfrac{7}{8}\cdot m=-1\\ \\m=-\dfrac{8}{7}

is the slope of needed line.

This line passes through the point (-4,2), so its coordinates satisfy the equation:

2=-\dfrac{8}{7}\cdot (-4)+b\\ \\b=2-\dfrac{32}{7}=-\dfrac{18}{7}

Therefore, the equation of the line is

y=-\dfrac{8}{7}x-\dfrac{18}{7}

Answer:

a)  W(x)  =  2, 000  - 275 x  represents the given situation.

b) The cost of the computer after 6 years is $350.

Step-by-step explanation:

Initial worth of the company = $2,000

Depreciation each year = $275

Let, W(x) represent the worth of the computer in x - th year.

So, according to the question:

a)   W(x)  =  2, 000  - 275 x  represents the given situation.

b)  Solving W(x) for x = 6, we get

    W(6)  =  2,000  - 275(6)  = 2, 000  -  1,650

              = 350

⇒W(6)  = $350

Hence, the cost of the computer after 6 years is $350.
