Answer:
C) f(3) = 111
Step-by-step explanation:
f(x) = 3x^3 + 8x^2 – 10x – 12
Let x=3
f(3) = 3(3)^3 + 8(3)^2 – 10(3) – 12
=3*27+8(9) -30-12
=81+72-30-12
=111
X=5
Y=1
2x+4(2x-11)=6
+44 both sides
2x+8x=50
10x=50
Divide by 10 both sides
X=5
Plug in 5 to x and you will find y

Answer:
22 Red Jellybeans
Step-by-step explanation:
Out of the 55 jellybeans in the jar, 40% of them are red, which means you have to do 40% of 55 to see which ones are red. We know 10% of 55 is 5.5, then multiply 5.5 x 4 to get 22 is 40% of 50 hope this helped :)
