Solve, then write, each equation in slope intercept form.
Answer:
1) (3,5)
2) (4,-7)
3) (6,4)
4) (-4,-3)
Step-by-step explanation:
1)
Subtract y from both sides of the equation.
x = 8 − y
x − y = −2
Replace all occurrences of x in x − y = −2 with 8 − y.
x = 8 − y
(8 − y) − y = −2
Subtract y from −y.
x = 8 − y
8 − 2y = −2
Solve for y in the second equation.
x = 8 − y
y = 5
Replace all occurrences of y in x = 8 − y with 5.
x = 8 −(5)
y = 5
Simplify 8 −(5).
x = 3
y = 5
Slope = (3,5)
2)
Multiply each term by 2 and simplify.
2x+y=12
y+6=−x−4
Move all terms containing variables to the left side of the equation.
2x+y=1x+2
y+6=−4
Move all terms not containing a variable to the right side of the equation.
2x+y=1x+2
y=−10
Multiply each equation by the value that makes the coefficients of x opposite.
2x+y=1(−2)⋅
(x+2y)=(−2)(−10)

Add the two equations together to eliminate x from the system.
2x+y=1+−2x−4
y=20−3
y=21
Divide each term by −3 and simplify.
y = −7
Substitute the value found for y into one of the original equations, then solve for x.
x = 4
slope (4,-7)
3)
Subtract y from both sides of the equation.
2x−y=8x−y=2
Multiply each equation by the value that makes the coefficients of y opposite
2x−y=8(−1)⋅
(x−y)=(−1)(2)
Simplify. 2x−y=8
−x+y=−2
Add the two equations together to eliminate y from the system.
2x−y=8 + −x+y=−2x=6
Substitute the value found for x into one of the original equations, then solve for y.
y=4
slope (6,4)
4)
Simplify 2(x+1).
y−3=2x+2
y=−3(x+5)
Simplify −3(x+5)
y−3=2x+2
y=−3x−15
Move all terms containing variables to the left side of the equation.
−2x+y−3=2
y=−3x−15
Add 3x to both sides of the equation.
−2x+y−3=2
y+3x=−15
Move all terms not containing a variable to the right side of the equation.
−2x+y=5
y+3x=−15
Reorder the polynomial.
−2x+y=5
3x + y=−15
Multiply each equation by the value that makes the coefficients of y opposite.
−2x+y=5(−1)⋅
(3x+y)=(−1)(−15)
Simplify.
−2x+y=5
−3x−y=15
Add the two equations together to eliminate y from the system.
−2x+y=5 + −3x−y=15−5x=20
Divide each term by −5 and simplify.
x=−4
Substitute the value found for x into one of the original equations, then solve for y.
y=−3

Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest
integer.
// we also have to se only one variable to solve this equation.
like this x+3 would be okay
Answer: 9
Step-by-step explanation:
Let the consecutive odd numbers be y, y+2 and y+4.
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:
5y = 2(y+4) + 7
5y = 2y + 8 + 7
5y = 2y + 15
5y - 2y = 15
y = 3
The smallest odd number is 5
The largest integer will be:
= y + 4
= 5+4
= 9

Answer:
1) Function
2) Function
3) Not a Function
Step-by-step explanation:
Using the vertical line test, using a pen, pencil or finger to move it vertically, I determined that 2 of the 3 questions was a function because the last question would not be a function since there are two lines instead of one when doing the test. Hope this helps!
Graph A:
It is a function.
Graph B:

We have,
Vertical line test:
If every vertical line intersects the graph at most once, meaning that no two different points on the graph lie on the same vertical line, then the graph represents a function.
Now,
Graph A:
Any vertical line will touch only once on the graph.
It is a function.
Graph B:
Any vertical line will touch only once on the graph.
It is a function.
Graph C:
Any vertical line will touch more than once on the graph.

The fourth term of an Arithmetic Sequence is equal to 3 times the first term, and the seventh term exceeds twice the third term by 1. find the first term and common difference.
Answer:
The first term is 3. The common difference is 2.
Step-by-step explanation:
The first term is x.
The common difference is d.
The second term is x + d.
3rd term: x + 2d
4th term: x + 3d
7th term: x + 6d
"The fourth term of an Arithmetic Sequence is equal to 3 times the first term"
x + 3d = 3 * x Eq. 1
"the seventh term exceeds twice the third term by 1"
x + 6d = 2(x + 2d) + 1 Eq. 2
Simplify Eq. 1:
2x = 3d
Simplify Eq. 2:
x + 6d = 2x + 4d + 1
x = 2d - 1
Multiply both sides of the last equation by 2.
2x = 4d - 2
2x = 3d (simplified Eq. 1)
Since 2x = 2x, then the right sides are equal.
3d = 4d - 2
d = 2
2x = 3d
2x = 3(2)
2x = 6
x = 3
Answer: The first term is 3. The common difference is 2.

1. Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting seashells. Marisol started with zero seashells in her collection.
• Pilar adds 10 seashells to her collection each week for x weeks.
• Marisol adds 20 seashells to her collection each week for x weeks.
(a) Write an inequality to represent the situation when the number of seashells in Marisol's collection is greater than the number of seashells in Pilar's collection.
(b) Solve the inequality in part (a) for the x. Show your work and explain your answer.
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8

(a+b)^3+8c^3
Answer:
(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Step-by-step explanation:
Given
(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
Thus
(a + b)³ + 8c³
= (a + b)³ + (2c)³
= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )
= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Janelle bought a notebook and three mechanical pencils for $4.75, while Sharai bought two notebooks and one mechanical pencil for $3.25. What is the cost of a mechanical pencil?
Answer:
mechanical pencil costs $1.25 each
Step-by-step explanation:
First, lets define our variables:
notebook = n
mechanical pencil = p
Next, we need to set up two equations using the information given:
n + 3p = 4.75
2n + p = 3.25
Next, lets take the first equation and solve for n.
n+ 3p = 4.75
n = 4.75 - 3p
Now we can replace "n" in the second equation with "4.75 - 3p".
2n + p = 3.25
2(4.75 - 3p) + p =3.25
9.5 - 6p + p = 3.25
9.5 - 5 p = 3.25
9.5 = 5p + 3.25
5p = 6.25
p = 1.25
Finally, we can go a step further and solve for "n" by plugging "p" back into the second formula:
n = 4.75 - 3(1.25)
n = 1.0
