Answer: −2.4f − 22
Step-by-step explanation: simply combine like terms. -2.7f + .3f would be -2.4f, and -14 - 8 is -22.
Answer:
21 is 35% of 60
Step-by-step explanation:
35% can be written as 0.35
0.35x = 21 ----- 0.35 times a number is 21
divide both sides by 0.35:
x = 60
These are "composite" functions.
g(x+a) means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
= -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.
