Answer:
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.
Step-by-step explanation:
Answer:
7xy + 2x^2t
Step by step explanation:
You just group the like terms and simplify (pay attention to the signs)
5xy + 2xy = 7xy
-1x^2t + 3x^2t = 2x^2t
So the answer is : 7xy + 2x^2t
D) 27 is the most accurate answer to 28
Answer:
k=-9
Step-by-step explanation:
198 - 13k = 7(-9k-36)
198 - 13k = -63k-252
63k-13k= -252 - 198
50k= -450
k=-9
Answer:
n=5
Step-by-step explanation:
1/4(2n +6) = 4
Multiply each side by 4
4*1/4(2n +6) = 4*4
(2n +6) = 16
Subtract 6 from each side
2n+6-6 = 16-6
2n = 10
Divide each side by 2
2n/2 = 10/2
n =5
