Answer:

7) First Circle

8)Also First Circle

Step-by-step explanation:

For the first one simplify the bottom expression to get (x-3)(x+7), then cancel out the numerator and x+7 to get 1/x-3. The restrictions are when you solve for x-3 and x+7

The second one is the same thing but this time we simplify the numerator to get (x+2)(x-5). Then, cancel out both x+2. Then you get x-5 as the answer and the restriction is -2 because x+2 is the denominator.

Hope this helps!

a rental car agency charges a flat fee of $110 plus $46 per day to rent a certain car. another agency charges a fee of $70 plus

insens350 [35]

First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:
let x= the number of days
110+46(x)=70+54(x)
Solve:
110-70+46(x)=70-70+54(x)
40+46(x)=54(x)
40+46(x)-46(x)=54(x)-46(x)
40=8(x)
40/8=8x/8
5=x
Therefore your answer would be 5 days

In the first bounce, the height that the ball reaches was 125 inches.
