Answer:
A' (-2,8) B' (-2,-4) C' (4,-4)
Step-by-step explanation:
Dilations Rule :
(x,y) → (kx,ky)
Scale factor = K
When your scale factor is more than one our triangle gets bigger. When your scale factor is less than one our triangle gets smaller.
( you plug in 2 in every point and those are your answers).
Remember negative times negative is positive and positive times negative is negative.
Answer:
1/2
or
0.5
Step-by-step explanation:
you need to get the line in the form of y = mx + b
2x - 4y = 10 Subtract 3x from both sides
-4y = - 2x + 10 3x on the left disappears. Divide by - 4
-4y/-4 =-2x/-4 +10/-4 Do the division
y = (2/4)x - 2.5
y = (1/2)x - 2.5
The slope is the number in front of the x
y = 0.5x - 2.5
Answer:
B. B is 0.535; It is a decay factor.
Step-by-step explanation:
I calculated it logically
What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
The answer is 6/4 but simplified it is 3/2
