Solve for the unknown values <br><br> X = ?<br> Y = ?
vovikov84 [41]

Step-by-step explanation:

So 95 is a linear pair. a linear pair adds up to 180 so 180 - 95 = 85

X = 85

y = 50

What is absolute value? can you solve problems using the absolute value?
vesna_86 [32]
An absolute value is positive value of any value. So the abs value of -28 is 28. The abs value of 67 is 67. Makes sense?

If it were |27-3| for example, treat the inside of a abs as parenthesis, so you must complete PEMDAS inside of it to reduce the equation to |24|, unless you wanted it to become |27| - |3|.

For functions, this becomes slightly different and more difficult, especially when adding a variable such as x. Look below for a sample equation.

|2x-3|=1

This equation will actually have (and most others) 2 solutions for x. To find these, you’ll need to multiply the inside of the abs by -1 for one equation, and leave it as it is for the other!

2x-3=1 -(2x-3)=1

Now you have to solve BOTH equations to get your correct x-value answers.

For the first listed equation:

2x=4

x=2

For the second listed equation:

-2x+3=1

-2x=-2

x=-1

So you get the x-values -1 and 2 which both make the parent function true!

y = x2 − 6x + 8 2y + x = 4 The pair of points representing the solution set of this system of equations is
algol [13]
2y + x = 4
x = -2y + 4

y = x^2 - 6x + 8
y = (-2y + 4)^2 - 6(-2y + 4) + 8
y = (-2y + 4)(-2y + 4) + 12y - 24 + 8
y = 4y^2 - 8y - 8y + 16 + 12y - 24 + 8
y = 4y^2 - 4y 
4y^2 - 4y - y = 0
4y^2 - 5y = 0
y(4y - 5) = 0
 
y = 0                x = -2y + 4
                        x = -2(0) + 4
                        x = 4

4y - 5 = 0          x = -2y + 4
4y = 5               x = -2(5/4) + 4
y = 5/4              x = -10/4 + 4
                         x = -10/4 + 16/4
                         x = 6/4 which reduces to 3/2

so u have 2 sets of points that will work....

(4,0) and (3/2,5/4) <===

jose jumped 8 1/3 feet. this was 2 1/3 feet farther than lila jumped. how far did lila jump TELL MEH AFTER THIS I GET ON IXL
nika2105 [10]
In this scenario Jose jumped the distance Lila jumped plus 2 1/3 ft, so...

Lilia + 2 1/3 = 8 1/3

subtract 2 1/3 from each side to get Lila by herself

Lila = 8 1/3 - 2 1/3
Lila = 6

Lila jumped 6 feet
