F -3
G 3
H 6
I. 9​

Answers

Answer 1
Answer:

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

f(x) = 2x^2 + x - 12

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9

u would use dmas :

519 + 2000 - 55 + 999

519 + 2000 + 999 = 3518

3518 -55 = 3463 

hope this helps

What is division?

Division means the separation of something into different parts, sharing of something among different people, places, etc.

A class of 25 students shares a class set of 100 markers. On a day there are 5 students absent. Then we have

The number of the marker for one student will be

\rightarrow (100)/(20) \n\n\rightarrow 5

Hence, one student has five markers.

Raoul scored 34 points during the basketball game. He scored 2/5 of his team's points. Write an equation that could be used to find the number of points p his team scored.

Answers

Answer:2/5(x)= 34

Step-by-step explanation:2/5 of the total points are equal to his total score. His total score is 34, so 2/5 times total score would equal his score. Total points scored is 85.

X=34/.4

X=85
