X+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
Answer:
30, 5 , 21
Step-by-step explanation:
substitute the values of x into f(x) , then
f(- 5) = (- 5)² + 5 = 25 + 5 = 30
f(0) = 0² + 5 = 0 + 5 = 5
f(4) = 4² + 5 = 16 + 5 = 21
The answer is S it’s the midpoint
