For [tex]2>x[/tex], or [tex]x<2[/tex]:
The solution set is [tex]\{{1,0-1,-2,-3,-4,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]2>x[/tex]
For [tex]3x+4\ge -8[/tex]:
We have to solve first
[tex]3x+4\ge -8\\3x\ge -8-4\\3x\ge -12\\x\ge -4\\[/tex]
The solution set is [tex]\{{-4,-3,-2,-1,0,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]3x+4\ge -8[/tex]
For [tex]5x\le 2x-3[/tex]:
We have to solve first
[tex]5x\le 2x-3\\5x-2x\le-3\\3x\le-3\\x\le-1[/tex]
The solution set is [tex]\{{-1,-2,-3,-4,-5,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]5x\le 2x-3[/tex]
For [tex]-6<4-2x[/tex]:
We have to solve first
[tex]-6<4-2x\\2x<4+6\\2x<10\\x<5[/tex]
The solution set is [tex]\{{4,3,2,...,-3,-4,-5,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]-6<4-2x[/tex]
So, [tex]-4[/tex] is a part of the solution set of all the inequalities.

What number does this Roman numeral represent?
XXXII
Answer: 32
Step-by-step explanation:
The roman numeral XXXII is 32 and XXIII is 23.
The number for this Roman numeral XXXII is, 32
Given that,
We have to write the number for this Roman numeral XXXII.
Since, We know that,
X represent in number = 10
I represent in number = 1
Hence, The number for this Roman numeral XXXII is,
⇒ XXXII
⇒ (10 + 10 + 10 + 1 + 1)

Given the complementary angle of y is 43º. Find the supplementary angle of y
Step-by-step explanation:
complementary = adds up to 90 degrees.
supplementary = adds up to 180 degrees.
the complementary angle of y is 43 degrees.
so, y = 90 - 43 = 47 degrees.
the supplementary angle of y = 47 is
180 - 47 = 133 degrees
Hello!
Given the complementary angle of y is 43º.
90 - 43 => 47°
Find the supplementary angle of y
180-43 => 137°

Find the distance between the points (13, 20) and (18, 8).
13
7
11
Answer: 13
Step-by-step explanation:
See attached graph.
A third point (18,20) may be added to the two given points to form a right triangle with sides 5 and 12. The distance, x, between the original two points is given by x^2 = 5^2 + 12^2
x^2 = 25 + 144
X^2 = 169
x = 13
help me with this problem thank youuup.
Step-by-step explanation:
it is a linear function, if the change in y is constant in relation to the changes of x.
in other words, if the slope y change/x change is the same for every point.
when we look at the table, we see x changes constantly by +2.
and y changes constantly by -6.
so, the change rate/slope is constantly -6/2 = -3.
and therefore it is a linear function.
the equation looks like (the slope is always the factor of x)
y = -3x + b
b we get by using one of the x,y pairs like 1,4
4 = -3×1 + b = -3 + b
b = 7
so, the full equation is
y = -3x + 7
Step-by-step explanation:
Given the table of values, {(-3, 16), (-1, 10), (1, 4), (3, -2), (5, -8)}:
We must determine whether the given relation or data can be modeled by a linear equation. It is necessary to analyze the pattern that exists between changes in y-values, along with the changes in x-values.
X-coordinates:Subtracting the x-coordinates provides a constant difference of 2:
Starting with the first two rows, given by the ordered pairs, (-3, 16) and (-1, 10): Subtract the two x-coordinates: -1 - (-3) = -1 + 3 = 2.For the second and third rows, given by the ordered pairs, (-1, 10) and (1, 4): Subtract the two x-coordinates: 1 - (-1) = 1 + 1 = 2.If you perform these same steps throught the remaining rows, then you'll get the same difference of 2.
Y-coordinates:We can perform the same steps for the y-coordinates. Subtracting the y-coordinates provides a constant difference of -6.
Starting with the first two rows, given by the ordered pairs, (-3, 16) and (-1, 10): Subtract the two y-coordinates: 10 - 16 = -6.For the second and third rows, given by the ordered pairs, (-1, 10) and (1, 4): Subtract the two y-coordinates: 4 - 10 = -6.If you perform these same steps throught the remaining rows, then you'll get the same difference of -6.
SlopeSince the constant change in y = -6, and the constant change in x = 2, then we can calculate for the slope as: Δy/Δx = -6/2 = - 3. Hence, the constant rate of change = -3.
As demonstrated throughout this post, we can infer that there is a linear pattern that exists between the x- and y-values.
Therefore, the data can be modeled by a linear equation because the rate of change is constant.
Linear Equation:In order to establish the linear equation that represents y as a function of x, we can use the slope, m = -3, and one of the given ordered pairs, (1, 4), to solve for the value of the y-intercept, b. Substitute these values into the slope-intercept form, y = mx + b:
y = mx + b
4 = (-3)1 + b
4 = -3 + b
Add 3 to both sides to isolate b:
4 + 3 = -3 + 3 + b
7 = b
Therefore, the linear equation that represents the given data is: y = -3x + 7.

0.25x^2-9
Step-by-step explanation:
Difference of squares converse:
0.25x^2-9
Answer:
0.25x^2-9
Step-by-step explanation:
multiply 0.5x with 0.5x which is 0.25x^2. then multiply 0.5x with 3 which is 1.5x. then multiply -3 with 0.5x which is -1.5x. then multiply -3 with 3 which is 9. so you will have 0.25x^2+1.5x-1.5x-9.
1.5x and -1.5x is 0. so you are left with 0.25x^2-9
