Determine which diagram could be used to prove △ABC ~ △EDC using similarity transformations. Triangle A B C is rotated about point C and then dilated to form triangle C E D. Triangle A B C is reflected across point C and then is rotated to form triangle C E D. Triangles A B C and C E D do not have congruent angle measures.

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?

5. (04.07)which of the following exponential functions goes through the points (1, 12) and (2, 36)? (2 points)f(x) = 3(4)^xf(x) = 4(3)^-xf(x) = 3(4)^-xf(x) = 4(3)^x
