What is 5.5-x=-4.5-x
konstantin123 [22]
<h3>Simplifying </h3>

5.5 + -1x = -4.5 + -1x

<h3> Add 'x' to each side of the equation. </h3>

5.5 + -1x + x = -4.5 + -1x + x

<h3> Combine like terms: </h3>

-1x + x = 0

5.5 + 0 = -4.5 + -1x + x

5.5 = -4.5 + -1x + x

<h3> Combine like terms:</h3>

-1x + x = 0

5.5 = -4.5 + 0

5.5 = -4.5

<h3> Solving: </h3>

5.5 = -4.5

<h3> This equation is invalid, the left and right sides are not equal, therefore there is no solution.</h3><h3 />

Hope this helps!

Which of the following is the maximum value of the function y = -x2 + 2x + 1?
Romashka-Z-Leto [24]

We first complete the square.

y=-x^2+2x+1

y=-x^2+2x-1+1+1

y=-(x-1)^2+2

The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.

The maximum point is (1,2) but the maximum value means the y value which is simply just 2.

Done!
