triangle is graft on a coordinate grid and then translated three units to the left in two units up. Of one vertice of The original triangle is located at (1,-8) what is the order pair of this vertex of the new triangle after translation?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

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