How does the graph of y = alx - 5)2 + k change if the value of his doubled?

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
