well #7 is a solution.
y= 9x (4,36)
9 times 4 = 36
36/9=4
so the ordered pair is a solution.
y=3x-5 (7,16)
3 times 7 -5= 16
so once again the ordered pair is a solution.
Hoped this helped.
Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7
Sphere surface area is A=4pi*r^2. So r is sqrt(A/4pi)
r=4cm. So d=8cm
