Answer:
6
Step-by-step explanation:
Hello :
<span>If f(x) = x + 8 and h(x) = 3x − 3,
</span><span>g ∘ f = h
</span>g ∘ (f ∘ f ^-1) = h ∘ f ^-1 ( proprety associative)
but ;
(f ∘ f ^-1) = x
g ∘ x = g
g(x) = (h ∘ f ^-1)(x)
calculate : (f ^-1)(x)
f(x) = x +8
x= f(x) - 8
so : (f ^-1)(x) = x - 8
g(x) = (h ∘ f ^-1)(x) = h((f ^-1)(x)) = h(x - 8) = 3(x - 8) -3
g(x) = 3x - 27
Answer:
pete brought 63 carrots
Step-by-step explanation:
70 x .90 = 63
The formula for unit rate is blank over blank = x over one. She types 496 words in 8 minutes, otherwise said "496 words per 8 minutes", which means its 496 over 8. If you do cross multiplication, 496*1 = 496 (Obviously) and 8*x = 8x.
Now, you have 496 = 8x. To isolate the variable, do the opposite of what it says 8x divided by 8 = x. Of course, you have to do the same thing on both sides. 496 divided by 8 is 62. so the unit rate is 62 words per minute.
