Answer:
<u>x=1
</u>
Step-by-step explanation:
5x-7=-10x+8
5x=−10x+8+7
5x=−10x+15
5x+10x=15
15x=15
<u>Answer:</u> <u>x=1
</u>

I think you probably meant <span>(x+2)^2+4 because the equation you have provided is not written in proper formatting and would actually be a straight line. However, if you meant for that second 2 to be an exponent, you now have a quadratic equation which would graph as a parabola. Remember the basic formula is y=(x-h)^2 +k where (h,k) is your vertex. So you change the sign of the number in the parenthesis, but not the number outside the parenthesis when finding the vertex. If there is a negative number in front of your equation, then the parabola is flipped upside down so the vertex would be a maximum, but if it is positive, or has nothing in front of it, then the parabola sits up like a bowl so the vertex is a minimum.</span>
Check the picture below.
so if we just find its vertex, we know how many feet it went up by its y-coordinate.
