Answer:
f(10) = 8
Step-by-step explanation:
f(x) = 4(x - 8)
Let x = 10
f(10) = 4 ( 10-8)
= 4 ( 2)
= 8
I DONT REMEMBER BUT IM PRETTY SURE ITS 2
That's a tough problem to type out! Thanks for sharing this image of the original expression.
What I'd do would be to write:
(fourth root of 9)^(x/2) = [ (9)^(1/4) ]^(x/2) = 9^(x/8)
so the second of the four possible answer choices seems correct.
Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b
so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3
Y= -8x + 11 I hope this helps
