Your teacher is giving a test worth 200 points. There are a total of 32 four-point and seven-point questions. How many 4 and 7-point questions are on the test?

a+b=32

4a+7b=200

a = 15

b = 20

There are 15 four pointers and 20 seven pointers. You can plug in the numbers to check.

it only 5 points but it’s okay.

Step-by-step explanation:

f(x) = y

f(-3) = -5

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
