Help is needed :) not sure what to do?

The coordinates of CD are C (-7,-2) and D (-3,-5). Point E is the midpoint of CD. What are the coordinates of the midpoint E?

goldenfox [79]

The coordinates of the midpoint of CD with endpoint at C(-7,-2) and D(-3,-5) is E(-5, -3.5)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let (x, y) represent the coordinate of the midpoint E. Point E is the midpoint of CD, hence:

x = [(-7) + (-3)] / 2 = -5

y = [(-2) + (-5)] / 2 = -3.5

The coordinates of the midpoint of CD with endpoint at C(-7,-2) and D(-3,-5) is E(-5, -3.5)

Find the missing values in the following figures

jekas [21]

Answer:

15.

x = 40/9 = 4 4/9

z = 24/5 = 4 4/5

17.

x = 50

y ≈ 11.5

Step-by-step explanation:

15. Corresponding segments are proportional:

top right side / whole right side = x / 8

5/(5+4) = x/8

x = 8(5/9) = 40/9

x = 4 4/9

__

right side bottom / right side top = z / 6

z = 6(4/5) = 24/5

z = 4 4/5

____

17. The acute angles are complementary:

x = 90 -40 = 50

__

From the Pythagorean theorem:

y = √(15² -9.6²) = √132.84

y ≈ 11.5

Solve (x +9)2 = 25.

alexandr1967 [171]

Answer:

$x = - 4 \: or \: x = - 14$

Step-by-step explanation:

We have been given the equation

$(x + 9) {}^{2} = 25$

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

$\sqrt{(x + 9) {}^{2} } = \sqrt{25}$

$x + 9 = \: 15$

$x + 9 = 5 \: or \: x + 9 = - 5$

$x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 = - 5 - 9$

$x = - 4 \: or \: x = - 14$

THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION

$x + 9 = 5 \: then \: x = - 4. \\ x + 9 = - 5 \: then \: x = - 14$
