3 is being squared that is an exponet
so the times its self 2 times
3*3=9
so the problem would become:
5+9-7+1
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.

Answer:
71%
Step-by-step explanation:
Firstly, 200 - 58 = 142
Next, 142 / 200 = 0.71
