Answer-3
Explanation-Subtract 3 from the -9. That will end up being -6. Then, divide that -6 by -2. That will give you your answer of 3.
Hope this helped you :)))))))
Answer:
4/3
Step-by-step explanation:
slope equation is y2-y1 over x2- x1. resulting in your slope of 4/3
Given:
A dilation with scale factor 2 maps triangle RST to triangle R'S'T'.
The perimeter of triangle RST is 60 units.
To find:
The perimeter of triangle R'S'T'.
Solution:
We know that the dilated figure is similar to the given figure.
The scale factor is 2. It means the side length of the dilated figure is twice then the original figure. So, the ratio of side of original figure to side of dilated figure is 1:2.
Let the perimeter of triangle R'S'T' be x.
The ratio of perimeters of similar figure is equal to the ratio of the corresponding sides of similar figures.




Therefore, the perimeter of triangle R'S'T' is 120.
The total distance covered is 6 m
<u>Step-by-step explanation:</u>
Let the total distance be '2d'
Total time = 1.25hrs
Downhill speed = 6 mphr
Uphill speed = 4 mphr
(d/6) +(d/4) = 1.25
(2d + 3d) /12 = 1.25
5d/12 = 1.25
d = 3m
So, 2d = 6 m
The total distance covered is 6 m
