X+y=8 You can find more Solutions by replacing x with other values and then solving for Y. For example, let X = 6. What is y? ... the solutions of x+y=8 x is 5 and y is 3
Answer:
Step-by-step explanation:
x + y = 8 ⇔ y = - x + 8
If x = 6 , then y = - 6 + 8 = 2
( 6, 2 )
If x = 0 , then y = 0 + 8 = 8
(0, 8)
If x = 8 , then y = - 8 + 8 = 0
(8, 0)

Converse: If line x and y are parallel then angles on the same line are supplementary angles.
Step-by-step explanation:
Converse:
Let's start with the converse, so if line x and y are parallel then angles on the same line are supplementary angles. I'm not sure if that's the converse your teacher wants but my teacher taught me this.
Finding x:
Now we know that the angles are supplementary angles, that means if w add them together we get 180°. So our equation will be [tex]10x-22+3x+7=180[/tex]. Now we just solve it. We start by combining like terms, then adding the 15 to both sides, and lastly we divide the 13 to both sides and get...
[tex]10x-22+3x+7=180\\13x-15=180\\13x=195\\x=15[/tex]
x=15
A line includes the points (-39,49) and (0,0). What is its equation in slope-intercept form?
Answer:
The equation in the slope-intercept form will be:
[tex]y=-\frac{49}{39}x+0[/tex]
Step-by-step explanation:
Given the points
(-39,49) (0,0)Finding the slope between the points using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-39,\:49\right),\:\left(x_2,\:y_2\right)=\left(0,\:0\right)[/tex]
[tex]m=\frac{0-49}{0-\left(-39\right)}[/tex]
[tex]m=-\frac{49}{39}[/tex]
We know that the point-slope of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting [tex]m=-\frac{49}{39}[/tex] and (-39,49) in the equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]
Now writing the equation in slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]
[tex]y-49=\frac{-49}{39}\left(x+39\right)[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]y-49=-\frac{49}{39}\left(x+39\right)[/tex]
[tex]\mathrm{Add\:}49\mathrm{\:to\:both\:sides}[/tex]
[tex]y-49+49=-\frac{49}{39}\left(x+39\right)+49[/tex]
[tex]y=-\frac{49}{39}x+0[/tex] ∵ [tex]y=mx+b[/tex]
Where
[tex]m=-\frac{49}{39}[/tex] and the y-intercept i.e. [tex]b=0[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=-\frac{49}{39}x+0[/tex]

The lager of two numbers is 15 more than three times the smaller.If the sum of the two numbers is 63,find the numbers
Answer:
The numbers are:
The smaller number = 12The larger number = 51Step-by-step explanation:
Let 'x' be the smaller number
As the lager of two numbers is 15 more than three times the smaller. so,
The larger number = 3x+15
As the sum of the two numbers is 63, so the equation becomes
[tex]x + 3x + 15 = 63[/tex]
[tex]x+3x=63-15[/tex]
[tex]4x=48[/tex]
Divide both sides of the equation by
[tex]\frac{4x}{4}=\frac{48}{4}[/tex]
[tex]x = 12[/tex]
Therefore,
The smaller number = x = 12
The larger number = 3x+15 = 3(12) + 15 = 36+15 = 51
Hence, the numbers are:
The smaller number = 12The larger number = 51Solve the equation for all real values of x.

How can real life problems involving one variable be modeled and solved?
Answer:
Writing an equation to model a real-world problem is often easier when you take the information given in the problem and express it in verbal form by using a few key words. This is very similar to translating verbal phrases into variable expressions. The difference is you will be translating a verbal sentence into an equation. Then, you can solve the equation using inverse operations.
Let’s look at an example.
Monica purchased a pair of tennis shoes that had this sticker on the bottom of the shoe.
$99.00$65.99
Use a verbal model to write and solve an equation to determine the amount of money Monica saved by purchasing the shoes on sale.
First, write a verbal model to represent the problem.
Verbal Model:
Sales Price+Amount Saved=Original Price
Next, name the variable.
Let ‘
s
’ represent the amount saved.
Next, solve the equation you have written. Remember an equation is like a balance scale. To keep the scale balanced, what you do to one side of the equation you must also do to the other side. When solving an equation your goal is to isolate the variable on one side of the equation and the numerical terms on the other side. This is done by performing inverse operations.
65.99+s=99.00
First, isolate the variable ‘
s
’ by subtracting 65.99 from both sides of the equation. Subtraction is the inverse of addition.
65.99−65.99+s=99.00−65.99
Next, simplify each side.
s=33.01
The answer is $33.01.
A variable can be any element that we can, in some way, change.
The general form of modeling and solving real life problems that involve one variable is:
Identify what the variable is and define it.Write the equation.Isolate the variable on one side of the equation.So for example, something that we can define with a variable is "How many of one type of item we can buy if we know its price"
For example, if we know that a shirt costs $10, then the price of x of these shirts is:
y = $10*x
Now, if you know how much money you have, you can use this equation to find how many shirts you can buy.
For example, you know that you have $20, then y = $20
$20 = $10*x
To solve this we need to isolate the variable on one side:
$20/$10 = x
2 = x
You can buy two shirts.
