A rock-climbing gym charges nonmembers $18 per
to use the wall plus $7 per day for equipment rental. Members pay an
annual fee of $400 plus $5 per day for equipment rental. How many days must both a member and a nonmember use the wall in one year both pay the same amount

20 days.

25d=400+5d

20d=400

d=400/20=20

d= 20 days

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
