using the equation for the transformation:
(x+1, 3y)
add 1 to very X and multiply y by 3
so (-2,0) becomes (-1,0)
(-2,3) becomes (-1,9)
(-5,1) becomes (-4,3)
new coordinates are (-1,0) (-1,9) (-4,3)
you don't have an image attached, so to see if they are congruent, the sides need to stay the same lengths and the angles need to stay the same, from the coordinates of the new triangle, I would say they are not congruent
Tim counts:
11 tens:
11x10=110
and 2 ones:
110+2= 112
Tim counted 112 bounces.
Distance=√(x2−x1)2+(y2−y1)2 Distance = x 2 - x 1 2 + y 2 - y 1 2. Substitute the actual values of the points into the distance formula. √((8)−(3))2+((−7)−(−5))2 8 - 3 2 + - 7 - - 5 2. Simplify.
A) 20%
b) 83%
hope I helped ^^
