Answer: (x - 4) (3x + 2)
<u>Step-by-step explanation:</u>
Factor 3x² - 10x - 8
a) Multiply the first and last coefficients: 3(-8) = -24
b) Find two numbers whose product equals -24 and sum equals -10 (the middle coefficient).
-24
∧
1 -24
2 -12 This works!
c) Replace the the middle term of -10x with 2x - 12x
3x² + 2x - 12x - 8
d) Split the equation into two sections (left and right) and factor each side separately.
3x² + 2x - 12x - 8
x(3x + 2) -4(3x + 2)
e) Notice that the parenthesis are the same. The values on the outside combine to make one of the factors and the parenthesis are the other factor.
x(<u>3x + 2</u>) -4(<u>3x + 2</u>)
= (x - 4) (3x + 2)
Answer:
(x+9, y+3)
Step-by-step explanation:
The graph shows that T(x, y) = (x+3, y+1).
Application of that transform again gives ...
T²(x, y) = T(T(x, y)) = T(x +3, y +1) = ((x +3)+3, (y+1)+1) = (x+6, y+2)
and again ...
T³(x, y) = T(T²(x, y)) = T(x+6, y+2) = ((x+6)+3, (y+2)+1)
T³(x, y) = (x +9, y +3)
Answer: -3, -5, -7 from top to bottom
Step-by-step explanation:
just plug in the x to the function f(x)=-x
which mean f(x)=-3, f(x)=-5, f(x)=-7
