Easy
(g o f)(-5)=g(f(-5))
first evaluate f(-5), then input the result into g(x)
f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3
g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6
(g o f)(-5)=-6
Answer:c- sixty nine hundredths
Step-by-step explanation:
three tenths can be expressed in decimal as 3/10
thirty nine hundredths can be expressed in decimal as 39/100
Therefore the sum of three tenths plus thirty nine hundredths equals
3/10 +39/100
We first find the l.c.m of the two fractions equals 100 so we have 100 as the denominator
then 100 divided by 10 multiplied by 3 +100 divided by 100 multiplied by 39 as illustrated below gives the answer
3/10 +39/100
=30+39/100
=69/100= sixty nine hundredths
