Answer:
1.) r>-3/4 and 2.) 157<-1
Given coordinates of the triangle RST are R(2,1), S(2,-2) and T(-1,-1).
Center of center of dilation is (2,-2).
Because center of dilation is (2,-2) so the coordinates of dilated image S(2,-2) would stay same.
Now, we need to apply rule for dilation with the scale factor 5/3.
Each of R(2,1), and T(-1,-1) would be and R' and T' would be in ratio 5/3.
We will extend RS to 5 units and TS also 5 units.
The new resulting image would be dilated triangle by a scale factor 5/3.
If u can help with this question, the options for both x' s are -8,-7,-6,-5,-4,-3,-2,-1,1,2,3,4,5,6,7,8

1x + 1y = 100....multiply by -3/8
3/8x + 7/8y = 2000
no need to multiply the other equation by anything....the x's will cancel because one will be -3/8x and one will be 3/8x
Distance = 13.243 * 22.07= 292.27miles
