Step-by-step explanation:
No real solutions exist. Subtract 8 on both sides to get:
[tex]x^2=-20[/tex]
You cannot take the square root of a negative number without involving imaginary numbers.
Answer and Explanation
__________________________________________________________
-10__________________________________________________________
The answer is -10 because...
You need to multiply 2 by "x," and to find out what "x" is, we need to add...
[tex]2+-12[/tex]
__________________________________________________________
And if we add [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.
__________________________________________________________
and now, if we add [tex]-20[/tex] by [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

Urgent help on math plz
Answers
Answer:
x = 14
Step-by-step explanation:
First, organize your work by showing that lines are similar
Line KV is similar to line RV
Line UV is similar to line LV
etc, etc.
=========================================
Now notice that line KV and line RV have the numbers 9 and 18 accordingly
and notice that it's an x2 difference.
==============================================
Now apply the same thing to line UV and LV and divide 26 by 2
That gets us 13
=======================================
Now plug 13 into the equation (2x - 15)
2x - 15 = 13
==========================================
Now solve for X
2x - 15 = 13
Add 15 to each side
2x − 15 + 15 =13 + 15
2x = 28
Divide both sides by 2
2x / 2 = 28 / 2
x = 14
I have to turn it in by tonight
Answers
Answer: (x,y) -> (x,-y)
Step-by-step explanation:
If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.
Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

A group of students go to the store to buy school supplies. If they buy three
binders and four notebooks, the bill will be $4.85. If they buy three binders and
ten notebooks, the bill will be $8.75. What is the cost of each binder and
notebook?
Answers
Answer: Binder = 75c notebook = 65c
Step-by-step explanation:
3b + 10n = 875
3b + 4n = 485
Subtracting gives:
6n = 390
390/6 = 65
n = 65
Substitute 65 into 3b + 4n = 485
3b + 260 = 485
3b = 485 - 260
3b = 260
b = 75

Find the slope that passes through the line (9, 3) and (2, 7)
Answers
Answer:
-4 / 7
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
m = (7 - 3) / (2 - 9)
m = 4 / -7
m = -4 / 7
OR
m = (y2 - y1) / (x2 - x1)
m = (3 - 7) / (9 - 2)
m = -4 / 7
