Slope-intercept form: y=mx+b
The slope is 8. This means that 8 multiplied by x is the slope of the line, and if there was no y-intercept then the first point would be (1,8) so 8 would be unit rate.
The y-intercept is -12. This means that though the slope of the line would still be 8, you move the point down on the y-axis by 12. The y-coordinate will always be 12 less than 8 times x

Step-by-step explanation:
There are nine letters in the word SEVENTEEN:
1 S
4 Es
1 V
2 Ns
1 T
Possible positions:
For the S, any one of the nine positions. That's ⁹C₁ positions.
For the Es, any four of the remaining eight positions. That's ⁸C₄ positions.
For the V, any one of the remaining four positions. That's ⁴C₁ positions.
For the N, any two of the remaining three positions. That's ³C₂ positions.
For the T, only one way to fill the last position. That's ¹C₁ position.
Total number of positions
= ⁹C₁ × ⁸C₄ × ⁴C₁ × ³C₂ × ¹C₁ = 9 × 70 × 4 × 3 × 1
= 7560
There are 7560 permutations of the letters in the word SEVENTEEN.

solve for y
13 = 6 + y
13 - 6 is 7
7 + 6 = 13
Just subtract the 2 numbers and you get your answer.
Final answer:
The equation 13 = 6 + y is solved by subtracting 6 from both sides, yielding y = 7.
Explanation:
To solve for y in the equation 13 = 6 + y, we need to isolate y on one side of the equation. We can do this by subtracting 6 from both sides of the equation.
Here is how you can solve the equation step by step:
Start with the original equation: 13 = 6 + y.
Subtract 6 from both sides: 13 - 6 = 6 + y - 6.
This simplifies to: 7 = y.
So, the value of y is 7.

Which statement is the correct interpretation of the inequality –5 > –6? (1 point)
Select one:
a. On a number line, −5 is located to the left of 0 and –6 is located to the right of 0.
b. On a number line, −5 is located to the right of 0 and –6 is located to the left of 0.
c. On a number line, −5 is located to the left of –6.
d. On a number line, −5 is located to the right of –6.
Answer: OPTION D.
Step-by-step explanation:
The symbol of the inequality ">" means "greater than". Then, -5 is greater than -6.
If a negative number -a is greater than other negative number -b , then the distance between -a and zero is shorter than the distance between -b and zero.
You can see in the number line attached that -5 is closer to 0 than -6. Therefore, -5 is located to the right of -6.

Pete played 18 tennis matches in a week. Jack played 6 fewer matches than Pete.
How many times the number of matches pete played is the number of matches jack played?
Answer:
Pete played 1.5 times the number of matches that Jack played.Step-by-step explanation:
Pete played 18 tennis matches in a week.
P = 18
Jack played 6 fewer matches than Pete.
J = P - 6
J = 18 - 6
J = 12
How many times the number of matches pete played is the number of matches jack played?
18 / 12 = 1.5
Pete played 1.5 times the number of matches that Jack played.
Answer:
Pete played 1.5 times the amount of matches Jack did.
Step-by-step explanation:
In order to find this, first find the number that Jack played. Since he played 6 fewer than Pete we can solve by subtracting 6 from Pete's number.
18 - 6 = 12
Now to find how many more times higher it is, divide the number Pete does by Jack's number. 18/12 = 1.5

An employee’s new salary is $16,275 after getting a 5% raise. What was the salary before the increase in pay?
Answer:
$15,500
Step-by-step explanation:
Let s represent the initial salary. That salary, plus a 5% raise, comes out to 1.05s = $16,275.
Solve for s by dividing both sides by 1.05:
s = $16,275 / 1.05 = $15,500.
The original salary was $15,500.
Final answer:
The original salary before a 5% raise resulting in a new salary of $16,275 was $15,500. We found this by dividing the new salary by 1.05.
Explanation:
The question asks us to determine an employee's original salary before a 5% raise. To solve this, we assume that the new salary ($16,275) is 105% of the original salary (100% + 5% raise). Therefore, we can set up the following equation: Original Salary × 1.05 = $16,275. Now, we want to find the Original Salary, so we divide $16,275 by 1.05.
Original Salary = $16,275 ÷ 1.05
When we divide $16,275 by 1.05, we get the Original Salary = $15,500.
Therefore, before the increase in pay, the employee's salary was $15,500.

Answer:
5.32255
Step-by-step explanation:
if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.
What is the area of a circle?It is the closely curving line drawn from the center to an equally distant point. The distance separating a circle's center and perimeter is its radius.
Let r be the radius of the circle. Then the area of the circle is written as,
A = πr² square units
The area of the circle is 89 square feet. Then the radius of the circle will be given as,
89 = πr²
Simplify the equation, then the radius is written as,
πr² = 89
r² = 28.34
r = 5.32 feet
if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.

Numbers 3-4, you already have the name, BUT you have to classify if the sides are equal. So, for 3-4 ALSO put, “ top and bottom are equal “ or “sides are the same” so for the rhombus, as an example, say, “all sides are the same”..understand?
A computer cost £900. It is on sale for 25% off. You also need to pay 6% sales tax. What is the final price of the computer?
First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225
so we subtract 225 from 900 and get 675 pounds.
to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50
675 + 40.50 = 715.5 pounds
Write the equation of the line in slope-intercept form using the two points: E(-1, 3) and F(-2, -3).
Answer:
[tex]\large\boxed{y=6x+9}[/tex]
Step-by-step explanation:
The slope-intercept form of the equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points E(-1, 3) and F(-2, -3). Substitute:
[tex]m=\dfrac{-3-3}{-2-(-1)}=\dfrac{-6}{-2+1}=\dfrac{-6}{-1}=6[/tex]
Therefore the equation of a line is:
[tex]y=6x+b[/tex]
Put the coordinates of the point E(-1, 3) to the equation and solve it for b:
[tex]3=6(-1)+b[/tex]
[tex]3=-6+b[/tex] add 6 to both sides
[tex]9=b\to b=9[/tex]
Finally we have:

consider the equation x^2=36. Which of the statements below are true? select all that apply
Answer:
See possible solutions below.
Step-by-step explanation:
The equation x^2 = 36 is a polynomial equation.
It can be solved by using a radical on both sides. The solution is x = +/- 6.
The equation has two solutions. x = -6, 6.
While this is a polynomial equation, it is specifically called a quadratic since the exponent is 2.
The equation x^2 = 36 has two real number solutions: x = 6 and x = -6. Statements that acknowledge both of these solutions as possible would be true.
Explanation:The equation in question is x^2 = 36. To solve this equation, one must realize that there are two real number solutions since squaring either a positive or negative number will result in a positive number. Taking the square root of both sides of the equation gives us two solutions: x = 6 and x = -6.
Therefore, any statement claiming that there is only one solution is incorrect. The true statements would acknowledge the existence of two solutions, one positive and one negative.

Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals. Maggie keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns over another tile without looking. What is the probability that the second tile that Maggie turns over has a plant on it?
Answer:6/8 - - - - simplified 3/4
Step-by-step explanation: removing the tile she just flipped over would be 6 plants and 2 animals so there would be 8 total tiles and you would putt the remaining tiles over it like so 6/8 meaning out of the remaining 8 tiles 6 of them are plants giving her a 6 in 8 chance or a 3 in 4 chance
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .
Number of tiles with picture of plants =7
Number of tiles with picture of animals =2
Total number of tiles =7+2=9
We have to find the probability that the second tile that Maggie turns over has plant on it .
When she removes one tile of picture of plant then she has number of tiles of picture of plants =6
Total number of tiles =8
Probability,P(E)=[tex]\frac{Number\;of\;favorable\;cases}{Total\;number\;of\;cases}[/tex]
Using the formula then we get
The probability that she finds tile of picture of plant =[tex]\frac{6}{8}=\frac{3}{4}[/tex]

The difference between the two roots of the equation 3x2+10x+c=0 is 4 2/3 . Find the solutions for the equation.
Answer:
x1 = - 4
x2 = 2/3
Step-by-step explanation:
Divide the equation by 3 to give
x^2 + 10x/3 + c/3 = 0
The sum of the two roots = - 10/3
So
x1 + x2 = -10/3
x1 - x2 = 4 2/3 Add these two equations.
2x1 = -10/3 + 4 2/3 Change 4 2/3 to an improper fraction
2x1 = -10/3 + 14/3 Combine the right
2x1 = 4/3 Divide by 2
2x1/2 =4/3//2
x1 = 2/3
=====================
x1 + x2 = - 10/3
2/3 + x2 = - 10/3
x2 = - 10/3 - 2/3
x2= -12/3
x2 = - 4
=================
(x - 2/3)(x +4) = 0 Multiply through by 3
(3x - 2)(x + 4) =0
==============
Check
(3x - 2)(x + 4) = 0
3x^2 + 12x - 2x - 8 =0
3x^2 + 10x - 8 = 0
