Answer:
d
Step-by-step explanation:
Given
-
x - 9 = - 27 ( add 9 to both sides )
-
x = - 18 ( multiply both sides by 2 to clear the fraction )
- 3x = - 36 ( divide both sides by - 3 )
x = 12 → d
Answer:
Step-by-step explanation:
hello,
we need to evaluate f(15) so
f(15)=4*15-3=60-3=57
Hope this helps
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
Answer: D ) 24
If im right it should be 116
