Answer:
f(-7) = 34
Step-by-step explanation:
If f(x) = -5x - 1, then . . .
f(x) = -5x - 1
f(-7) = -5(-7) - 1
= 35 - 1
= 34
. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.

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!
Answer:
D
Step-by-step explanation:
This should be easy one unless you're making silly mistake like forgetting to take reciprocal of 
lets do it:
÷ first: we take the reciprocal of 3/2x now its
* 
now just multiply top and bottom by using distributive method
this is your answer.
