First, we want to subtract function f minus function g to get a new function:
(f-g)(x)= x+12 - (-2x)
(f-g)(x)= x+12+2x
(f-g)(x)= 3x+12
Now, we want to plug in 144 for x:
<span>(f-g)(144)=(3)(144)+12
</span>(f-g)(144)=432 +12
<span>(f-g)(144)=444
</span>
Therefore, the answer is 444
Answer:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
Answer:
Add 64
Step-by-step explanation:
x^2 - 16x
<em><u>If you add 64, you get x^2 - 16x + 64 which factors as (x - 8)^2</u></em>
