(x - 12)(x + 2)
Step-by-step explanation:
Given
x² - 10x - 24
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 12 and + 2 , since
- 12 × + 2 = - 24 and - 12 + 2 = - 10 , thus
x² - 10x - 24 = (x - 12)(x + 2) ← in factored form

Use compositions to verify that g and g^-1 are in fact inverses.
g(x): 1/x+2
g^-1(x): 1/x - 2
Answer:
as written there, they are not inverses
proof by counter example: since g(1) = 3 , but g^-1(3) = -5/3 != 1
Step-by-step explanation:
g(g^-1(x)) == x if they are indeed inverses
1/(1/x -2) + 2 = x/(1-2x) + 2 != x so, they are not inverses
What is the average rate of change of y with respect to x over the interval [-2, 6] for the function y = 5x + 2?
Answer:
5
Step-by-step explanation:
Average rate of change is slope, which is change in y over change in x:
[tex]\frac{[5(6)+2]-[5(-2)+2]}{6-(-2)} =\frac{32-(-8)}{8} =5[/tex]
The average rate of change of the function is 5.
What is the average rate of change of a function?The sum of the change in the function values (output values) divided by the change in the input values is the average rate of change between two input values.
The given interval is [-2,6] and the given function is f(x) = y = 5x + 2.
The value of the function for x = 6 is:
f(6) = 5(6) + 2
f(6) = 32
The value of f(x) for x = -2 is:
f (-2) = 5(-2) + 2
f(-2) = -10 + 2
f(-2) = -8
The average rate of change of the function is given by:
( f(6) - f(-2) )/ (6 - (-2))
= ( 32 - (-8))/ (6 + 2)
= ( 32 + 8)/8
= 40/8
= 5
Hence, the average rate of change of the function is 5.

Given M = the set of counting numbers and N = the set of even numbers, find M - N.
need answer
Answer:
M-N = set of odd numbers
M-N = 1,3,5,7,9,11,.....................................so on it till infinity
Step-by-step explanation:
M = the set of counting numbers
set of counting number are are all the numbers which is used for counting.
They are also called Natural numbers
In numerical form set of counting numbers can be represented as
M = the set of counting numbers = 1,2,3,4,5,6,7,8,9..............................till infinity
N = the set of even numbers
set of even numbers all the counting numbers which are multiple of two
In numerical form set of counting numbers can be represented as
N = the set of even numbers = 2,4,6,8,10,12................so on till infinity
__________________________________
now we have to find M-N
it means from set of counting number, all the even numbers would be excluded
IN such case
If we exclude all the even numbers, then only odd numbers will remain.
M-N will be = 1,3,5,7,9,11,.....................................so on it till infinity
If we look it closely , the given set is set of odd numbers
odd numbers are counting numbers in form of 2n+1 where n = 0,1,2,3....
Thus,
M-N can also be said as set of odd numbers
M-N = set of odd numbers
M-N = 1,3,5,7,9,11,.....................................so on it till infinity

Conjecture: Twice the number of units in the length of any side of a rectangle is equal to the number of square units in the area of the rectangle.
The area of ABDE is 4 and 2 X AB = 4
The area of ABCF is 2 and 2 x BC = 2.
The area of ABCF is 2 and 2 x AB = 4
The area of ABDE is 4 and 2 x BD = 4
The statement proves that the conjecture is
Answer:
The area of ABCF is 2 and 2 × AB = 4
The statement proves that the conjecture is false
Step-by-step explanation:
A conjecture is a proposition or conclusion that is presumed to be true or correct but which is based on incomplete details or information
Given the length of the sides of rectangle ABDE, we have;
Length AB = 2 units
Length DE = 2 units
The area of ABDE = 2 × 2 = 4 unit²
Therefore, the area of the rectangle ABDE is equal to 2 × the length of either AB or DE
However, the are of rectangle ABCF = 2 × 1 = 2 unit²
While the area of rectangle 2 × the length of side AB = 2 × 2 = 4 unit², which is not equal to the number of square units in the area of the rectangle.
Therefore;
The area of ABCF is 2 and 2 × AB = 4
The statement (above) proves that the conjecture is false.

What is the line parallel to y = 3x + 5 that passes through the point (-8,4) in SLOPE INTERCEPT FORM
Answer:
y= -3/5 x
Step-by-step explanation:
i do not know
Answer:
y = 3x + 28
Step-by-step explanation:
Slope intercept form is y=mx+b. Because it is said that the line were looking for is parallel I can put in the same slope. Parallel lines always have the same slope.
Then plug in the coordinates to find the y-intercept.
4 = 3(-8) + b
4 = -24 + b
+24 +24
28 = b
So we know that b is equal to 28 so we can plug that in to get y = 3x + 28

Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives. Which equation shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car? a. Y = 21x - .05 b. Y = -.05(x+21) c. Y = 21 - .05x d. Y =21 + .05x
Given:
Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives.
To find:
The equation which shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Solution:
We have,
Initial amount of gas in car = 21 gallons
So, y-intercept of the linear relationship is 21.
It uses approximately .05 gallons of gas each mile that she drives.
It means, the gas is decreased by .05 gallons for each mile.
So, slope of the linear relationship is -0.05. Here, negative sign represents the decrease in amount of gas.
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
Substitute m=-.05 and b=21 in the above equation.
[tex]y=-.05x+21[/tex]
[tex]y=21-.05x[/tex]
So, the equation [tex]y=21-.05x[/tex] represents the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Therefore, the correct option is c.

In step 1 she needed to divide by 3 rather than multiply. In step 2 she needed to add b rather than subtract. In step 3 she needed to subtract c rather than divide. Darpana solved the equation correctly.
Answer:
Option (c) is correct.
Step-by-step explanation:
Given equation is :

Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c

Find the distance between (4, -1) and (-2, -1). Round answer to the nearest tenth. *
Answer:
6
Step-by-step explanation:
You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.
(4, -1) (-2, -1)
The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.
===========================================
Work Shown:
[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]
This value is exact. No rounding is needed.
-------------
A shortcut is to subtract the x coordinates and apply absolute value
So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6
Or |x2-x1| = |-2-4| = |-6| = 6
This shortcut only works because the y coordinates the same for both points.
On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.

a rectangle is 3x feet long and 4feet wide.the value of the perimeter (in feet) is equal to the value of the area in square feet. find x
Answer:
x = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Rectangle:
Length = 3x feet
Width = 4 feet
Perimeter = 2*(length +width)
= 2* (3x + 4)
= 2*3x + 2*4
= 6x + 8
Area = length * width
= 3x * 4
= 12x
Area of rectangle = perimeter of rectangle
12x = 6x + 8 {Subtract 6x form both sides}
12x - 6x = 8
6x = 8 {Divide both sides by 6}
x = 8/6
x = [tex]\frac{4}{3}[/tex] feet
Answer:
3 feet x 4 feet= 12 feet

Find the remainder when f(x) is divided by (x - k).
f(x) = 4x3 - 6x2 + 3x + 1; k= -2
Answer:
The remainder is -61
Step-by-step explanation:
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
The given polynomial is:
[tex]f(x) = 4x^3 - 6x^2 + 3x + 1[/tex]
We need to find the remainder when f(x) is divided by x+2. According to the above-mentioned theorem, we only need to find f(-2) as follows:
[tex]f(-2) = 4(-2)^3 - 6(-2)^2 + 3(-2) + 1[/tex]
[tex]f(-2) = 4(-8) - 6(4) - 6 + 1[/tex]
[tex]f(-2) = -32 - 24 - 6 + 1=-61[/tex]
The remainder is -61
