Put the values of x to the equations of the functions:
1. f(9) → x = 9; f(x) = -3x + 10
f(9) = -3(9) + 10 = -27 + 10 = -17
2. f(-2) → x = -2; f(x) = 4x - 1
f(-2) = 4(-2) - 1 = -8 - 1 = -9
3. f(-5) → x = -5; f(x) = -2x + 8
f(-5) = -2(-5) + 8 = 10 + 8 = 18
I believe it's also 98 degrees, because the are symmetrical.
You have to subtract 3.2 from 3.5 to get x. 0.3+ 3.2=2.5 so x=0.3
Answer:
30(D)
Step-by-step explanation:
38.48-26.94=11.54
11.54÷38.48×100
≈30
Answer: 1682
(45 x 36) + 62
1620 + 62 = 1682
