Simplify the expression and find its value when x = -3 and
y=5.
2 (x² + 2xy) +5 - xy + y2​

Answer 1

Answer:

Start with the given equation.

2%280%29-5y=10 Plug in x=0.

0-5y=10 Multiply 2 and 0 to get 0.

-5y=10 Simplify.

y=%2810%29%2F%28-5%29 Divide both sides by -5 to isolate y.

y=-2 Reduce.

So the y-intercept is .

Notice that if we graph the equation 2x-5y=10, we can see that the graph has the x-intercept and the y-intercept
