Answer:
Correct choce is (a). 30.
Step-by-step explanation:
Given equation is
.
Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:
(a). 30
(a). 33
(a). 6
(a). -6
Now let's find 







Hence correct choce is (a). 30.
slope (m) = rate. $40 per hour is the rate, so m = 45
y-intercept (b) = one time fee. $45 is the flat rate which is the one time fee, so b = 45
y = mx + b
y = 40x + 45
Answer: A
Answer:
x = 10
Step-by-step explanation:
1) Subtract x from both sides.
4x − x = 30
2) Simplify 4−x to 3x
3x = 30
3) Divide both sides by 3
x = 
4) Simplify
to 10
x = 10
