Answer: (f·f)(0) = 4
(fof)(0) = -8
<u>Step-by-step explanation:</u>
f(x) = 3x - 2
(f·f)(x) = (3x - 2)(3x - 2)
= 9x² - 12x + 4
(f·f)(0) = 9(0)² - 12(0) + 4
= 4
(fof) = 3(3x - 2) - 2
= 9x - 8
(fof)(0) = 9(0) - 8
= -8
<em>I wasn't sure if you wanted multiplication or composition so I solved both</em>
Answer:
The slope of line a is * also.
Step-by-step explanation:
Parallel lines have the same slope. Whatever number, fraction, variable, symbol is given for the slope of one line, the other must have the same number, fraction, variable, symbol, if they are parallel.
Answer:
5 x 4 + 2 - 3 / 1
Step-by-step explanation:
Took me a lot of tries but got it! :) Hope this helps
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
