The 3rd one as it's cubic
Answer:
The first one.
Step-by-step explanation:
Find the asymptotes.
Vertical Asymptotes: x = − 2
Horizontal Asymptotes: y = 3
No Oblique Asymptotes
So it has to be y=(1)/(x+2)+3

Find the greatest common factor of 80 and 20.
Hello there!
The GCF of 80 and 20 is 20.
Because both numbers are evenly divisible by 20; this is their greatest common factor (GCF)
Therefore, the GCF is 20.Hope this helps you!

Find the intercepts for the graph of the equation.
-2x-2y = -4
Answer:
y= -x+2
Step-by-step explanation:
If what they are asking for is slope-intercept format, then you need to isolate the y on one side.
So add -2x to both sides to get, -2y= 2x-4
After that you would divide both sides by -2, and when you do this you are dividing every single term by -2 so you would get,
y= -x+2
that is your slope- intercept formula.
so your slope is m= -1
Answer:
X-intercept: (2,0)
Y-intercept: (0,2)
Step-by-step explanation:
all it's asking for when it says "find the intercepts" is for two points, the one with 0 in the x position, and the one with 0 in the y position of the point (x,y).
These are surprisingly easy! Just plug 0 into x and solve for y. In this case, that gives us (-2)x(0)-2y = -4
Do some algebra and you'll find that y = 2. Since we plugged in 0 for x, that gave us the y-intercept: (0,2). (Remember, the y-intercept is when it intersects the y-axis. All points on the y axis have an X coordinate of 0!)
Now do the same thing but plug 0 in for y.
-2x - (2)x(0) = -4
-2x = -4
x=2
This gives us the x-intercept of (2,0)

Which graph represents y as a function of x ?
Answer:
Top graph only
Step-by-step explanation:
A function links two set in a way that for each element from the origin set (called domain) you get one and only one element of the target set (co-domain, or range). In layman terms, once you pick your x, you get a single y. In term of graphing it it means that a vertical line of equation touches the function either zero times (c is outside the domain, or only once (if c is in the domain. If you try it on the various functions there are intervals where you are touching the graphs twice. Or even infinite times as it happens in the last one.

Factor the following trinomials. Show your work. Will mark as Brainliest if the answers are correct and have work shown.
1. -2x^2 - 10x + 100
2. 3x^3 + 9x^2 - 54x
3. x^2 +12x + 20
1st Question:
Our problem is [tex]-2x^2 - 10x + 100[/tex]
We have a common factor between the three terms, -2. So:
[tex]-2x^2 - 10x + 100[/tex]
[tex]-2(x^2 + 5x -50)[/tex]
We can factor further. What two numbers add up to 5 and multiply to -50? Our answer would be positive 10 and -5. Therefore:
[tex]-2(x^2 + 5x -50)[/tex]
[tex]-2(x +10)(x-5)[/tex]
2nd Question:
The problem is [tex]3x^3 + 9x^2 - 54x[/tex]
Like the first question, we can factor out a constant. In this case, we factor out a 3.
[tex]3x^3 + 9x^2 - 54x[/tex]
[tex]3(x^3 + 3x^2 - 18x)[/tex]
We can also factor out an x.
[tex]3(x^3 + 3x^2 - 18x)[/tex]
[tex]3x(x^2 + 3x - 18)[/tex]
We need to simply further. We can factor the quadratic into (x+6)(x-3).
[tex]3x(x^2 + 3x - 18)[/tex]
[tex]3x(x+6)(x-3)[/tex]
3rd Question:
Our problem is [tex]x^2 +12x + 20[/tex]
We do not have a coefficient, so we should factor the expression straight away. What two numbers add up to 12 and multiply to 20? the numbers 2 and 10. So:
[tex]x^2 +12x + 20[/tex]
[tex](x+2)(x+10)[/tex]

City Middle School is raising money for new gym equipment by selling cookie dough.
• 25% of all money collected from the sale will go towards the equipment.
• The sixth grade sold $511.94 worth of cookie dough.
• The seventh grade sold $385.96 worth of cookie dough.
• The eighth grade sold $491.12 worth of cookie dough.
About how much money did the school raise for the new gym equipment?
Explanation:
Add up the dollar figures given
511.94+385.96+491.12 = 1389.02
The school raised a total of $1,389.02
Of that total, 25% will go toward the gym equipment.
25% of 1389.02 = 0.25*1389.02 = 347.255 which rounds to 347.26
Answer:
$347.255
Step-by-step explanation:
add all the sales of sixth to eight grade and multiply to .25

c) Solution of 'Decrease 9 3/8 by 4.37' is 5.005.
d) Solution of 'Increase 5.4 by 1 1/27 is 5.81.
What is Division method?
Division method is used to distributing a group of things into equal parts.
Given that;
All questions are;
a) Increase 2.75 by 1/4
b) Divide 4 2/15 by 3.1
c) Decrease 9 3/8 by 4.37
d) Increase 5.4 by 1 1/27
Now, Solve the expression as;
a) Increase 2.75 by 1/4 = 2.75 + 1/4
= 2.75 + 0.25
= 3
Thus, Solution of ' Increase 2.75 by 1/4' is 3.
b) Divide 4 2/15 by 3.1 = 4 2/15 ÷ 3.1
= 62/15 ÷ 3.1
= 4.13 ÷ 3.1
= 1.33
Thus, Solution of 'Divide 4 2/15 by 3.1' is 1.33.
c) Decrease 9 3/8 by 4.37 = 9 3/8 - 4.37
= 75/8 - 4.37
= 9.375 - 4.37
= 5.005
Thus, Solution of 'Decrease 9 3/8 by 4.37' is 5.005.
d) Increase 5.4 by 1 1/27 = 5.4 + 11/27
= 5.4 + 0.41
= 5.81
Thus, Solution of 'Increase 5.4 by 1 1/27 is 5.81.
So,
a) Solution of ' Increase 2.75 by 1/4' is 3.
b) Solution of 'Divide 4 2/15 by 3.1' is 1.33.
c) Solution of 'Decrease 9 3/8 by 4.37' is 5.005.
d) Solution of 'Increase 5.4 by 1 1/27 is 5.81.

Given the diagram below, find the value of y.
Answer:
y = 9°
Step-by-step explanation:
These are vertical angles, so we can set them equal to each other.
Equation: (11y - 36)° = 63°
"Distribute:" 11y - 36° = 63°
Add 36 to both sides: 11y = 99°
Divide both sides by 11: y = 9°
Giving us an answer of: y = 9°
According to the Vertical Angle Theorem, 11y-36=63.
Solving this:
11y-36=63
11y=99
y=9

A line passes through (3, –2) and (6, 2). Write an equation for the line in point-slope form.
Rewrite the equation in standard form using integers.
A. y + 2 = 4/3(x – 3); –4x + 3y = –18
B. y – 3 = 4/3(x + 2); –4x + 3y = 17
C. y + 2 = 4/3(x + 3); –4x + 3y = –18
D. y – 2 = 4/3(x – 3); –4x + 3y = 18
Answer:
A. y + 2 = 4/3(x – 3); –4x + 3y = –18
Step-by-step explanation:
(3, –2) and (6, 2)
First, we must establish slope...
m=(y-y1)/(x-x1)
m=(-2-2)/(3-6)
m=-4/-3
m=4/3
Point slope formula is...
y-y1=m(x-x1)
Let's select either coordinate. I randomly select the first (3, –2)...
y--2=4/3(x-3)
Subtracting a negative number is the same as adding a positive number...
y+2=4/3(x-3)
This corresponds to the first answer.
Standard form...
Ax+By=C
y+2=(4/3)x-4
y=(4/3)x-6
-(4/3)x+y=-6
Multiply both sides by 3...
-4x+3y=-18
This also corresponds to the first answer.
How about the second coordinate, (6, 2)...
y-y1=m(x-x1)
y-2=(4/3)(x-6)
Let's convert it into standard form..
y-2=(4/3)x-8
y=(4/3)x-6
-(4/3)x+y=-6
Multiply both sides by 3...
-4x+3y=-18
FIRST ANSWER
y + 2 = 4/3(x – 3); –4x + 3y = –18
