12. -4x - 5y = 1
y = -5x - 3
what is the solution to the systemmm

Is the open sentence 5x-2=3x+2 true when x=2? justify your answer.

∆abc is reflected across the x-axis and translated 2 units up to give the image ∆a'b'c' with coordinates a'(1, 1), b'(2, -1), c'(2, 1). what are the coordinates of the preimage ∆abc? a. a(-1, 1), b(-2, 3), c(-2, 1) b. a(1, 1), b(2, 3), c(2, 1) c. a(1, -3), b(2, -1), c(2, -3) d. a(1, -3), b(2, -5), c(2, -3)

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer
