To set the equation,we can first find how much price would be raised within a year:

=500×(1+7%)

=500×1.07

As the years go by the increase would accumulate,and the equation would be:

$500 \times {1.07}^{t}$
Hope it helps!

What are the solutions to the nonlinear system of equations below?

Sonbull [250]

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.
