Answer: D
Step-by-step explanation:
If segment D moves downward it means its function has a negative slope so the line will be decreasing.
3(4y+17)-y=4
12y+51-y=4
11y+51=4
11y=-47
y=-47/11
x=4(-47/11)+17
x=-188/11+17
x=-1/11
hope this helps!

Answer:
12
Step-by-step explanation:
By ythagoras Theorem,
x^2 + 9^2 = 15^2
x^2 + 81 = 225
x^2 = 225 - 81
x^2 = 144
x = √144
x = 12
