Answer:
slope of M'N' = 1
Explanation:
First, we will need to get the coordinates of points M' and N':
We are given that the dilation factor (k) is 0.8
Therefore:
For point M':
x coordinate of M' = k * x coordinate of M
x coordinate of M' = 0.8 * 2 = 1.6
y coordinate of M' = k * y coordinate of M
y coordinate of M' = 0.8 * 4 = 3.2
Therefore, coordinates of M' are (1.6 , 3.2)
For point N':
x coordinate of N' = k * x coordinate of N
x coordinate of N' = 0.8 * 3 = 2.4
y coordinate of N' = k * y coordinate of N
y coordinate of N' = 0.8 * 5 = 4
Therefore, coordinates of M' are (2.4 , 4)
Then, we can get the slope of M'N':
slope = (y2-y1) / (x2-x1)
For M'N':
slope = (3.2-4) / (1.6-2.4)
slope = 1
Hope this helps :)
Girl I’m sorry but do u mean question ? ♀️ and its the third one I think

May you mark me brainelist
Answer:
See below in bold.
Step-by-step explanation:
3/10 + (-1/3)
= 3/10 - 1/3
Convert the fractions to denominator 30:
= 9/30 -10/30
= -1/30.
10. 14 - (-8)
= 14 + 8
= 22.
13. 2/3 - 3/2
The least common denominator is 6 so we have:
= 4/6 - 9/6
= - 5/6.
