Answer:

there is no real number solution

Step-by-step explanation:

Given

x² + 6x = - 10

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = - 10 + 9

(x + 3)² = - 1 ( take the square root of both sides )

x + 3 = ± \sqrt{-1}

there is no real number whose square is - 1

Solve the Equation.

<h2>1.</h2>

Firstly, combine like terms: 7r-8=10+r

Next, subtract r on both sides of the equation: 6r-8=10

Next, add 8 onto both sides of the equation: 6r=18

Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>

<h2>2.</h2>

Firstly, multiply both sides by e: TE=3u

Lastly, divide both sides by 3, and <em><u>your answer will be \frac{TE}{3}=u</u></em>

kramer

Answer:

The midpoint is at ( 1/2, 3/2)

Step-by-step explanation:

Midpoint

To find the x coordinate of the midpoint

Add the x coordinates of the endpoints and divide by 2

( -4+5)/2 = 1/2

To find the y coordinate of the midpoint

Add the y coordinates of the endpoints and divide by 2

( 4+-1)/2 = 3/2

The midpoint is at ( 1/2, 3/2)
