Using the piecewise function below, evaluate f(7) f(x) { 2x?, x27
(x + 3, x<7
000 to you
A. 7
B. 98
C. 10
D. 28

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %

150
