Mathematics

First you solve for y for the top equation, making the top equation become y=-3+5=x.
now we have to substitute that into 3x-8y=24.

that gives you 3x-8(-3+5x)=24
now you solve it for x, which is 0.
now you have to substitute 0 for x in the equation y=-3+5x, so it now becomes y=-3+5*0.
when you solve this for y, you get -3. this means your answer is y=-3 and x=0

Answer:

(7, 5)

Step-by-step explanation:

When reflecting over the x-axis, the only position that moves is the y-coordinate as it is going above the axis it was previously below. Since point F's original position was (7, -5) it is 5 spaces away from the x-axis. We move 5 places up to be even with the x-axis, then move up another 5 places to reflect the point to get F'.

Hope this Helps!
