I can't quite remember how to approach this one, I have three others, but I think I could solve them if someone helped walked me

through this one to jog my memory.

First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation.
(x+[])^2=[]
(x-[])^2=[]

If there is more than one solution, separate them with commas.

What is the midpoint of a segment with These endpoints (-12,-3) and (3,-8)
Savatey [412]

Answer:

(\frac{-9}{2},\frac{11}{2})

Step-by-step explanation:

you have to use the midpoint formula which is

(\frac{x1+x2}{2},\frac{y1+y2}{2})

so you plug your numbers in

(\frac{-12+3}{2},\frac{-3+-8}{2})

Add the tops

(\frac{-9}{2} ,\frac{-11}{2} )

if possible simplify

and that is your answer

The graph of the equation xy=4 is symmetric with respect to which of the following?
inna [77]
The graph of x and y = 4 is symmetric with respect to the line x = y.
 Therefore, the answer is the second option shown above, which is:

 <span>the line y = x</span>
 
 Below is a graph where you can see the symmetry of xy = 4 with respect to the oblique axis x = y. This axis cuts the curves just at its apex

How do I solve for x
Alchen [17]
Greetings!

To find the length of any side of a right triangle, you can use the Pythagorean Thereom. It states that the squares of two sides are equal to the square of the hypotenuse:
a^2+b^2=c^2

Input the information from the diagram into the formula: 
(x)^2+(x+7)^2=(13)^2

Expand each term:
(x)^2+(x+7)^2=(13)^2

x^2+((x+7)(x+7))=169

x^2+(x(x+7)+7(x+7))=169

x^2+x^2+7x+7x+49=169

Combine like terms:
2x^2+14x+49=169

Add -169 to both sides:
(2x^2+14x+49)+(-169)=(169)+(-169)

2x^2+14x-120=0

Factor out the Common Term (2):
2(x^2+7x-60)=0

Factor the Complex Trinomial:
2(x^2-5x+12x-60)=0

2(x(x-5)+12(x-5))=0

2(x-5)(x+12)=0

Set Factors to equal 0:
x-5=0

x=5

or

x+12=0

x=-12

However, since we are solving for the side length, the only possible answer is 5 (a shape can't have a side with a negative length.)

The Solution Is: 
\boxed{x=5}

I hope this helped!
