(3x^3 - 5x^2 -4x + 4) / (x-2) = (3x-2)(x+1) when x ≠2
Answer:
x
Step-by-step explanation:
f(x) = (x-1)/3
g(x) = 3x+1
f(x) °g(x) =
Substitute g(x) in for x in the function f(x)
f(x) °g(x) = (g(x) -1)/3
= (3x+1 -1)/3
= 3x /3
=x
Answer:
x ≈ 4.6
Step-by-step explanation:
Reference angle = 75°
Opposite side to reference angle = 17
Adjacent side = x
Applying TOA:
Tan 75 = opp/adj
Tan 75 = 17/x
Multiply both sides by x
x*Tan 75 = 17
Divide both sides by Tan 75
x = 17/Tan 75
x ≈ 4.6
A negative scale factor inverts the original image and scales it to what the number is.
An expansion means the image would get bigger.
For an image to get bigger the scale factor needs be be greater than 1.
-2 means the image would increase in size and be inverted.
2 means the image would increase in size.
The two correct scale factors are -2 and 2.
