H(x) = 5 - x
Domain: Df = R
f(x) = 3x + 2
Domain: Df = R
Dh = Df therefore (h·f)(x) = h(x) · f(x)
(h·f)(x) = (5 - x)(3x + 2) = 5(3x + 2) - x(3x + 2) = 5·3x + 5·2 - x·3x - x·2
= 15x + 10 - 3x² - 2x = -3x² + 13x + 10
Answer:
hot dogs are $1.50 and the potato chips are $1 each
Step-by-step explanation: you'd take 3 hot dogs add 1.50 each it would be $4.50+$3 for the bags of chips and you'd get $7.50
Answer:
He did NOT apply the distributive property correctly for 8(1 + 2i)
Joan: 12 years old
Amber: 22 years old
If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)
That’s 12 since we calculate the sides
