Which equation has infinitely many solutions? O 5(2x + 4) = 10x- 12
O 5(2r + 4) = 10(r + 2)
O 5(2r + 4) = 12r
O 5(2x + 10) = 20(x+ 1)

Olivia uses the work below to determine 55% of 720 which explains the error in olivia’s solution

Use the function f(x) is graphed below. the graph of the function to find, f(6). -2 -1 1 2

The graph is supposed to show f(x) = 3 sin (x/4+1) - 1/2. which of the following are correctly represented in the graph? select two of the following that apply.
