Answer: [tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex]
Step-by-step explanation:
To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[tex]\frac{y+4}{y-8} +\frac{y-8}{y+4}[/tex] [multiply first fraction by y+4 and second by y-8]
[tex]\frac{(y+4)(y+4)}{(y-8)(y+4)} +\frac{(y-8)(y-8)}{(y-8)(y+4)}[/tex] [distribute by FOIL]
[tex]\frac{y^2+8y+16}{(y-8)(y+4)} +\frac{y^2-16y+64}{(y-8)(y+4)}[/tex] [add numerator]
[tex]\frac{y^2+8y+16+y^2-16y+64}{(y-8)(y+4)}[/tex] [combine like terms]
[tex]\frac{2y^2-8y+80}{(y-8)(y+4)}[/tex] [factor out 2 from numerator]
[tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex]
Now we know that [tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex] is the factored form after adding.

A.Create a pair of equations same slope and different y-intercepts.
B. Create a pair of lines in which one line lies directly on top of the other.
C. Create a pair of equivalent equations.
D. Create a pair of lines that will always stay the same distance apart.
E. Create a pair of lines that intersect at only one point.
Answer:a and d
Step-by-step explanation:
i took the quiz
Steve can do are; A.Create a pair of equations same slope and different y-intercepts. D. Create a pair of lines that will always stay the same distance apart.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We have given that Steve wants to create a system of equations so that the system has no solution.
We know that when both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.
So the correct option that steve can do are;
A.Create a pair of equations same slope and different y-intercepts.
D. Create a pair of lines that will always stay the same distance apart.

This circle is centered at the point (2,6), and the length of its radius is 4. What is the equation of the circle?
Answer:
The equation of the circle with centre (h,k) and radius (r) can be written as :-
[tex] \\ \qquad \sf \: {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ [/tex]
So, we are given with :-
h = 2 k = 6 r = 4Now, by putting their value we can write the equation as :-
[tex] \\ \qquad\sf \: {(x - 2)}^{2} - {(y - 6)}^{2} = {4}^{2} (16) \\ [/tex]
Expanding this, we get :-
[tex] \\ \sf {x}^{2} - 4x + 4 + { y}^{2} - 12y + 36 = 16 \\ [/tex]
Rearranging and by subtracting by 16 from both sides we got standard polynomial as -
[tex] \\ \sf \: {x}^{2} + {y}^{2} - 4x - 12y + 20 = 0 \\ [/tex]
show that the angles of an equalateral triangle are 60°each
Answer:
For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.
Since, we know, that the sum of all angles of any triangle be 180° .
Let each angle be a.
Thus,
Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Maya painted 3/4 of her art project in the morning and 1/8 of her project in the evening which equation can Maya use c to find how much of the project she painted
The equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]
Let the size of the art be x.
In the morning, she paints 3/4 of x.
So, we have:
[tex]\mathbf{Morning = \frac 34 x}[/tex]
In the evening, she paints 1/8 of x.
So, we have:
[tex]\mathbf{Evening = \frac 18 x}[/tex]
So, the amount of project painted is:
[tex]\mathbf{c = Morning + Evening}[/tex]
This gives
[tex]\mathbf{c = \frac 34x + \frac 18x}[/tex]
Take LCM
[tex]\mathbf{c = \frac{6x + x}8}[/tex]
Add the numerator
[tex]\mathbf{c = \frac{7x}8}[/tex]
So, we have:
[tex]\mathbf{c = \frac{7}{8}x}[/tex]
Hence, the equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]

Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th floor to the street; but every time he returns, he rides the same self-service elevator only to the 15th floor, where he leaves the elevator and walks up the remaining five flights of stairs. What is happening? Why does he do that?
Answer:
He does that because he is short and his hand can't reach the 20th floor button
Step-by-step explanation:
Mitch does that simply because he is short.
When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.

Last summer, Fred earned 16 dollars per day, and Maria earned 18 dollars per day together, they earned 1780 dollars. If Fred worked 5 more days than Maria, how many days did Maria work?
x = # of days Maria worked
x + 5 = # of days Fred worded
$16(x + 5) + $18x = $1780
Let's distribute the $16
$16x + $80 + $18x = $1780
Combine like terms
$34x + $80 = $1780
Subtract $80 from both sides.
$34x = $1700
Divide both sides by $34
x = 50 days
Maria worked 50 days
Suppose S is between R and T. Use the Segment Addition Postulate to solve for z.. RS=2z+6, ST=4z−3, RT=5z+12
Answer:
9
Step-by-step explanation:
If S is between R and T, then RS+ST = RT
Given the following parameters
RS=2z+6,
ST=4z−3,
RT=5z+12
On substituting
2z+6+4z-3 = 5z+12
Collect like terms
2z+4z-5z = 12+3-6
6z-5z = 15-6
z = 9
Hence the value of z is 9

Blanca earns a yearly salary of $55,000. Isabel earns a yearly salary of $63,000. Blanca will receive a salary increase of $3,700 per year, and Isabel will receive a salary increase of $2,900 per year.
Which equation can be used to find n, the number of years it will take Blanca to earn the same salary as Isabel?
55,000n + 3,700 = 63,000 + 2,900n
55,000n + 3,700n = 63,000n + 2,900n
55,000n + 3,700n = 63,000n + 2,900
55,000 + 3,700n = 63,000 + 2,900n
PLSS ANSWER ILL MAKE MOST BRAINLIEST!!!!
Answer:
last choice: 55,000 + 3,700n = 63,000 + 2,900n
Step-by-step explanation:
Blanca's salary now: 55,000
Adding $3,700 per year will add 3,700n in year n.
Her salary in year n will be 55,000 + 3,700n
Isabel's salary now: 63,000
Adding $2,900 per year will add 2,900n in year n.
Her salary in year n will be 63,000 + 2,900n
We set the two total salaries equal:
55,000 + 3,700n = 63,000 + 2,900n

I have to find rs and rt
Answer:
RS= 20
ST= 40
RT=60
Step-by-step explanation:
If you notice, RS and ST make up RT. Therefore, we add RS and ST, and set that equal to RT.
3x-16+4x-8=60 [combine like terms]
7x-24=60 [add both sides by 24]
7x=84 [divide both sides by 7]
x=12
Now that we know x, we can plug them into RS.
3(12)-16 [multiply]
36-16 [subtract]
20
We can also find ST.

Find the slope of the line passing through the points (-18, -5) and (-19, -13)
Answer:
Let (-18, -5) be (x1,y1)
(-19, -13) be (x2,y2)
slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8
Answer: The slope is 8.
Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.
