4. Triangle XYZ is graphed on a coordinate grid with vertices at X(-2,5), Y(-1,-7), and Z(2,-4). Triangle XYZ is dilated by a scale factor of u with the origin as the center of dilation to create triangle X'Y'Z'. Which ordered pair represents the coordinates of the vertex Y'? A. (-1 + U, -7 + u)
(Yellow Hearts)
B. (-1 -u, -7 - u) (Red Hearts)
C. (-1u, -7u) (Pink Hearts)
D. (-7,-) (Green Hearts)​

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

pretty sure 750 each month!

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
