f(-2)=3(4)+1
=13
Answer:
Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
= =
ANSWER: X= 6
EXPLANATION: We know that AM = 6x and AM is half of AB so if we multiply 6x times 2 we get 12x. Which mean 12x= AB
We also know that AB= 10x + 12 so if both 10x + 12 and 12x equal AB we have to set them equal to each other to find out what x is
10x + 12= 12x
First subtract 12 on both sides then it should look like 10x= 12x - 12
Now subtract 12x from 10x and it should look like -2x= -12
Lastly divide everything by -2 and you get x= 6
hope this helps!!!! And I didn’t know if you needed the explanation but I just wrote it anyways
