Answer:

D 90

Step-by-step explanation:

x/4 ≥ 20

Multiply each side by 4

4*x/4 ≥ 20*4

x ≥ 80

The only number greater than or equal to 80 is 90

4 0

Answer: D. 90

Multiply both sides of the inequality by 4

4(X/4 )greater than or equal to (20)4

x greater than or equal to 80

So D must be the answer, since it is the only answer that is greater than 80.

The function C(x) = 25x + 50 represents the labor cost (in dollars) for Certified Remodeling to build a deck, where x is

Whitepunk [10]

Answer:

Master Remodeling

Step-by-step explanation:

<em>Original question is attached</em>

<h3>Option 1</h3>

C(x) = 25x + 50
C(8) = 25*8 + 50 = $250

<h3>Option 2</h3>

As per table, the rate of change is $30 per 2 hours.
So 8 hours will cost
$190 + $30 = $220

As we see the second option is cheaper so we should hire the Master Remodeling

7(y – 8) + 24 = x(y – 6)

ICE Princess25 [194]

Answer:y = y = (32 - 6x)/(7 - x)

Step-by-step explanation:

1. Distribute -> 7y - 56 + 24 = xy - 6x

2. Add Like Terms -> 7y - 32 = xy - 6x

3. Collect Like Terms -> 7y - xy = 32 - 6x

4. Factor Out the "y" -> y(7 - x) = 32 - 6x

5. Divide Out the Left "x" -> y = (32 - 6x)/(7 - x)
