5x+2=7x-4 what is x and if you can how you did it

∆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)

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
