21. Given: f(x) = (x - 2)2 + 4 g(x) = (x – 5)2 + 4 When compared to the graph of f(x), the graph of g(x) is
(1) shifted 3 units to the left
(2) shifted 3 units to the right
(3) shifted 5 units to the left

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
