Question

Simplify the expression and then evaluate it for the given value of the variable: (6−2x)+(15−3x) for x=−0.2

PLEASE HELP!!!!!!

Answer 1

20

Explanation:

The simplified expression is -5x+21

-5(0.2)+21=

-1+21= 20

Answer 2

24

Explanation:

f(x)= (6−2x)+(15−3x)

x=-0.2

f(-0.2)=(6−2(-0.2)+(15−3(-0.2))

f(-0.2)=(6+0.4)+(15+0.6)

f(-0.2)=6.4+15.6

f(-0.2)=22
