Answer:
F(x) = 5x + 7
F(5) = 5*5 + 7 = 25 + 7 = 32
Answer:
14
Step-by-step explanation:
70
1 * 70
5 * 14
7 * 10
42
1 * 42
3 * 14
7 * 6
28
1 * 28
2 * 14
7 * 4
pick the largest factor from 70 and check it they also work with the other two. 14 is the GCF.
Completing order of operations is the correct answer.
Work backward: Multiply out (x-8i) and (x+8i).
The product is x^2 - [64i^2], or x^2 - [-64], or x^2 + 64
This is equivalent to 1x^2 + 0x + 64, and so a=1, b=0 and c=64.
You have to add
So the coupon subtracts 17.95 from X price and you pay $71.80 for the headphones
17.95 + 71.80 = $89.75 (Original Price)
