What is the value of f(? 3) +f(7) f(-3) +f(7) when f(x)=? 3x+9 f(x)=-3x+9 ? 18 6 -6 -12

The correct answer is 6.

Step-by-step explanation:

To find this, first find f(-3)

f(x) = -3x + 9

f(-3) = -3(-3) + 9

f(-3) = 9 + 9

f(-3) = 18

Now we do the same for f(7)

f(x) = -3x + 9

f(7) = -3(7) + 9

f(7) = -21 + 9

f(7) = -12

Now we add them together

18 + -12 = 6

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
