Triangle ABC has vertices A(1, 4), B(1, 5), and C(1, 4). Triangle ABC is dilated and B’ is located at (-3, 15). Write an algebraic representation for the dilation. Determine the coordinates of the image of point A after the dilation.

answer: i don't understand. what are the options

step-by-step explanation:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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.

you can not solvr this without numbers
