Answer:
Step-by-step explanation:
[tex]x^2 - 2x = 120\\x^2 - 2x - 120 = 0[/tex]
We have to find the factors of 120 that can either add up to or have a difference of 2.
The factors of 120 are:
[tex]\pm 1, 120, 2, 60, 3, 40, 4, 30, 5, 44, 6, 20, 8, 15, 10, 12...[/tex]
The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:
[tex](x+10)(x-12)[/tex]

What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
Monthly private school tuition based on the average number of weeks in attendance is predicted using the least-square regression line.
y = 265.9 + 93.4x, where y represents the predicted monthly expense and x represents the average number of weeks in attendance.
A child attends private school an average of 3.5 weeks and has a monthly cost of $595.
Then the residual for the child will be
⇒ 595 – (265.9 + 93.4 × 3.5)
⇒ 595 – (592.8)
⇒ 2.2
Then the correct option is B.

Step-by-step explanation:
One factor of f(x) = x3 − 14x2 + 61x − 84 is (x − 7). What are the zeros of the function?
Answer:
-7
Step-by-step explanation:
Because zero is the x, so x=-7 then it's -7
The zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).
What is a polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
It is given that:
f(x) = x³ − 14x² + 61x − 84
One factor is (x - 7)
The cubic polynomial can be written as:
f(x) = (x - 7)(x² - 8x + 12)
Or
f(x) = (x - 7)(x - 3)(x - 4)
To find the zeroes equate to zero:
f(x) = 0
(x - 7)(x - 3)(x - 4) = 0
x = 7, x = 3, and x = 4
Thus, the zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).

plz help me and include the steps of how you got the answer.
Answer:
x = 17, y = 25.5
Step-by-step explanation:
Since ABC is congruent to DEF, we can say that angle A = D and B = E by CPCTC
So to find x we can do:
5x + 2 = 87
5x = 85
x=17
So x is 17
Since B = E and E is 42 degrees, then B must also be 42 degrees. So 87 , 42, and 2y must add up to 180 degrees because it is a triangle.
87 + 42 + 2y = 180 degrees
129 + 2y = 180
151 = 2y
y = 25.5
So x = 17 and y = 25.5

Well the equation is y - y1 = m ( x - x1)
-3 = y1
2 = x1
(2, -3)
Answer:
(2,-3)
Step-by-step explanation:
The given equation is in point-slope form. That is,
[tex]y-y1=m(x-x1)[/tex]
[tex]x1[/tex] and [tex]y1[/tex] is a point, while [tex]m[/tex] is the slope.

What is the equation of the line in slope-intercept form that is perpendicular to the line y = -x-2 and passes
through the point (-12, 10)?
O y=-x-6
O y=-x + 6
Oy= x + 26
O y = x + 10
The equation of the line that is perpendicular to y = -x - 2 and passes through the point (-12, 10) is y = x + 22 in slope-intercept form.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The given line has a slope of -1, since it is in the form y = mx + b, where m is the slope, and in this case, m = -1.
To find the equation of the line that is perpendicular to this line,
We need to use the fact that the product of the slopes of two perpendicular lines is -1.
Let the slope of the perpendicular line be m'.
Then:
-1 x m' = -1
m' = 1
So the slope of the perpendicular line is 1.
We also know that the perpendicular line passes through the point (-12, 10).
Using the point-slope form of the equation of a line, we have:
y - y(1) = m' (x - x(1))
Substituting m' = 1 and (x(1), y(1)) = (-12, 10),
We get:
y - 10 = 1 (x + 12)
Simplifying this equation gives:
y = x + 22
Thus,
The equation of the line that is perpendicular to y = -x - 2 and passes through the point (-12, 10) is y = x + 22 in slope-intercept form.

A local orange grower processes 2,330 oranges from his grove this year. The oranges are packaged in crates that each holds 96 oranges. All but one crate is full. How many oranges are in the last crate?
Answer:
13
Step-by-step explanation:
Given parameters:
Number of oranges processed by grower = 2330 oranges
Number of oranges per crate = 96
Unknown:
Number unpacked oranges
Solution:
To solve this problem, divide the total number of oranges by the number of oranges per crate;
Number of unpacked oranges = [tex]\frac{2330}{96}[/tex]
Number of unpacked oranges = 24 [tex]\frac{13}{48}[/tex]

Answer:
Question 1: Option C: y -6 = 8(x+4) is the correct answer.
Question 2: Option B: y-1=0 is the correct answer.
Step-by-step explanation:
Question 1(In Picture):
Given point is: (-4,6) and
Slope: m = 8
The point-slope form of equation of a line is given by:
[tex]y - y_1 = m(x-x_1)[/tex]
Here (x1,y1) are the coordinates of the point from which the line passes. Putting (-4,6) in the equation and slope
[tex]y -6 = 8(x+4)[/tex]
Hence,
Option C: y -6 = 8(x+4) is the correct answer.
Question 2:
Given point is: (3,1) and
Slope: m = 0
The point-slope form of equation of a line is given by:
[tex]y - y_1 = m(x-x_1)[/tex]
Here (x1,y1) are the coordinates of the point from which the line passes. Putting (-4,6) in the equation and slope
[tex]y -1 = 0(x-3)\\y-1 = 0[/tex]
Hence,
Option B: y-1=0 is the correct answer.

Answer:
The egg salad sandwich
Step-by-step explanation:
The cheese sandwich is 1/4 lb for 6 inches. For it to be proportional, the 12 inch would be twice that amount (2/4 or 1/2 lb). But, the actual 12 inch cheese sandwich is 3/4 lbs.
The chicken salad sandwich is 3/4 lbs for 6 inches. For it to be proportional, the 12 inch would be twice that amount (6/4 or 3/2 lbs). But, the actual 12 inch chicken salad sandwich is 7/4 lbs.
The egg salad sandwich is 2/3 lbs for 6 inches. For it to be proportional, the 12 inch would be twice that amount (4/3 lbs). The 12 inch sandwich is 4/3 lbs, so it is proportional.
The vegetable sandwich is 3/4 lbs for 6 inches. For it to be proportional, the 12 inch would be twice that amount (6/4 or 3/2 lbs). But, the actual 12 inch vegetable sandwich is 5/4 lbs.

Solve for x
x + 3 = y
Select the correct response
1. X=y/3
2.x= y+3
3.x=y+-3
4.x=3y
Answer:
3. x = y - 3
Step-by-step explanation:
You want to move all numbers on the same side of x to the other side with y. Whenever doing this, we have to reverse the operation. In this problem, we have + 3 with x. So we will need to subtract 3 from both sides.
x + 3 = y
x = y - 3

The circumference of a circle is 53.38 cm. The radius of the circle is 8.5 cm.
Which expression best represents the value of *sign*
Answer:6.28
Step-by-step explanation:
Expression that best represents value of π is C/2r,
Value of π used to calculate circumference is 3.14
What is circle?A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its center.
Given,
Circumference of circle C = 53.38
Radius of circle r = 8.5
C = 2πr
π = C/2r
π = 53.38/2 × 8.5
π = 53.38/17
π = 3.14
Hence, value of π is 3.14 for calculating circumference of circle, which can be calculated with expression C/2r
