Dilate at center of dilation at point A(-5,-7) with a scale factor of 3

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

x = 12

y = 1

for the points!

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
