f(-12) = -12(-12) + 100 = 144 + 100 = 244
Let's break this down:
The difference: Something's gotta be subtracted
Twice a number: So 2 times a number, or n
and 3: So we gotta subtract 2n and 3
is 11: The final answer is 11
So altogether is:
2n - 3 = 11
Answer:
x=5
Step-by-step explanation:
4x-3=2x+7
2x-3=7
2x=10
x=5
Since -1 is less than or equal to -1 you input it into the first equation.
-3•(-1) -4
3-4
-1
the answer is -1 good luck
