Answer:

74

Step-by-step explanation:

fg(x)=f[g(x)]

=f(-4x+7)

=3(-4x+7)+5

=-12x+26

When x=-4,

fg(-4)=-12(-4)+26

=74

Answer:

8 family members.  Average of 2.6 fish per person.

Step-by-step explanation:

How many family members caught fish?  Count only those members who caught at least 1 fish (that's all of them, because nobody caught 0 fish!).

3 + 1 + 0 + 4 = 8 family members.

Average number of fish caught <u>per person</u>.  This is the total number of fish caught divided by the total number of people.

This is a little bit tricky because, for example, 4 people caught 4 fish, making 4 x 4 = 16 fish caught.

Multiply number of fish (column 1) by the number of people (column 2):

1 x 3  +  2 x 1  +  3 x 0  + 4 x 4 = 3 + 2 + 0 + 16 = 21 fish caught.

21 fish.  8 people.  On average, that is 21 / 8 = 2.625 which rounds to 2.6 fish per person.

Hint:  the word "per" means <u>divide</u>, so "fish per person" tells you to divide the total number of fish by the total number of people.

Good Luck!

Answer:

r^2=(A/pi)

Step-by-step explanation:

if A=pi*r^2 then maybe dividing by pi to get r^2 alone says r^2=(A/pi) or to get rid of the exponent you may square root each side so r=(sqrt(A/pi))
