Answer:
x = -3, 0, 2
Step-by-step explanation:
=> x³ + x² - 6x = 0
=> x(x² + x - 6) = 0
=> x² + x - 6 = 0 or x = 0
=> x² + 3x - 2x - 6 = 0 or x = 0
=> x(x + 3) - 2(x + 3) = 0 or x = 0
=> (x + 3)(x - 2) = 0 or x = 0
=> x = - 3 or x = 2 or x = 0

Given:
On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).
To find:
The range of x-values extrapolation occurs.
Solution:
Consider the below figure attached with this question.
From the graph or given points it is clear that the x-values are 0, 1, 3, 4, 6.
It means the x-values are from 0 to 6.
So, the range of the x-values is [tex]x\geq 0[/tex] or [tex]x\leq 6[/tex].
The required compound inequality for the range of x-values is [tex]0\leq x\leq 6[/tex].
Therefore, the correct option is D.

Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answers
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
Hence the required answer is 25.55find the slope between (-3,2) and (-7,-16)
Answers
Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.

[tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex]
↓
[tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex]
Step-by-step explanation:
Given - The matrices are -
[tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex]
To find - Arrange the matrices in increasing order of their determinant values.
Proof -
Determinant of matrix [tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex] is
= (2)(4) - (6)(3)
= 8 - 18
= -10
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex] = -10
Determinant of matrix [tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex] is
= (-2)(9) - (-7)(5)
= -18 + 35
= 17
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex] = 17
Determinant of matrix [tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex] is
= (6)(-8) - (6)(5)
= -48 - 30
= -78
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex] = -78
Determinant of matrix [tex]\left[\begin{array}{ccc}2&4\\5&-5\\\end{array}\right][/tex] is
= (2)(-5) - (4)(5)
= -10 - 20
= -30
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&4\\5&-5\\\end{array}\right][/tex] = -30
Determinant of matrix [tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex] is
= (2)(4) - (5)(-2)
= 8 + 10
= 18
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex] = 18
Determinant of matrix [tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex] is
= (4)(2) - (-3)(5)
= 8 + 15
= 23
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex] = 23
Determinant of matrix [tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex] is
= (3)(6) - (2)(4)
= 18 - 8
= 10
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex] = 10
Now,
Increasing order of Determinant is -
-78 < -30 < -10 < 10 < 17 < 18 < 23
So,
Order of the Matrix will be
[tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex]

Amanda graphed line m and line n on a coordinate plane, as shown below.
Which of the following statements is true?
A. The slope of line m is greater then the slope of line n
B. The slope of line n is greater than the slope of line m
C. The x-intercept of line m is greater then the x -intercept of line n
D. The y-intercept of line n is greater then the y -intercept of line m.
Answers
Answer:
B
Step-by-step explanation:
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line n, I used the points (0,0) and (1,2). This means the slope will be 2-0/1-0. Simplify this to get 2/1 or 2. Therefore the slope for line n is 2.
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line m, I used the points (0,7) and (1,8). This means the slope will be 8-7/1-0. This will make the slope 1/1 or 1. Therefore, the slope for m is 1.
Therefore, the slope for line n is greater than the slope of line m.

Sin0=20/29 find tan 0
Answers
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21
In the diagram, O is circumscribed about quadrilateral ABCD. What is m<B?
Answers
Answer:
B; 94 degrees
Step-by-step explanation:
From the diagram, what we have is a cyclic quadrilateral
For a cyclic quadrilateral, opposite angles are supplementary
That means;
They add up to give 180 degrees
Mathematically;
angle D + angle B = 180
angle B = 180 - angle D
angle B = 180-86
angle B = 94 degrees
