The comparison of the inequalities that is correct among the given options is; D: -5 < -4
What is the comparison of the absolute values?We want to compare absolute values.
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3.
The absolute value of a number can also be described as its distance from zero along real number line.
A) |-3| > |-4|; This is incorrect because the absolute value of - 3 is 3 and the absolute value of - 4 is 4 and 4 is greater than 3 not the other way round.
B) Again, this is incorrect as the absolute value of 5 is 5 which is less than 7.
C) This is incorrect with the same reason as above.
D) This is correct because on a number line, - 5 is less than - 4

What is the domain of this relation?
Answer:
{-4, 0, 2, 5}
Step-by-step explanation:
The domain of a relation in a graph is a list of all the x values from the points plotted on it.
Therefore, we can take the coordinates of each point, and list all the x values. (You can't use the same number more than once)
Once you list all the x values, you put them in order from least to greatest, and then you're done! (make sure to use swirly brackets)

A 5oz jar of jam costs $2.50. How much is the unit price per ounce?
The unit price per ounce of the jar of jam is $0.50
How to determine the unit price per ounce for the jam?From the question, the given parameters are
Volume = 5 oz
Cost of jam = $2.50
The unit rate of the jam is calculated as
Unit rate = Cost of jam/Volume
Substitute the known values in the above equation
So, we have the following equation
Unit rate = 2.50/5
Evaluate the quotient
So, we have the following equation
Unit rate = 0.5
Hence, the unit price per ounce is $0.50

Use the number line below, where RS=9y+3, ST=5y+8, RT=67 a. What is the value of y? b. Find RS and ST.
The value of y on the number line is 4.
How to find the side of a number line?A number line is a series of numbers placed on a straight line in order from least to greatest.
The number line is RT.
The point S is in between RT.
Therefore,
RT = RS + ST
Hence,
RT = 67
RS = 9y + 3
ST = 5y + 8
Therefore,
RT = RS + ST
67 = 9y + 3 + 5y + 8
67 = 9y + 5y + 11
67 = 14y + 11
subtract 11 from both sides of the equation
67 = 14y + 11
67 - 11 = 14y + 11 - 11
56 = 14y
divide both sides by 14
y = 56 / 14
Therefore,
y = 4

Last night, Luis read 75% more pages than Dayja, and Dayja read 75% more pages than Michael. If Dayja read 84 pages, how many pages did Luis, Dayja, and Michael read all together?
Answer:
252
Step-by-step explanation:
Altogether, Luis, Dayja, and Michael read 279 pages.
How do we get the total number of pages read by each person?We can get the total number of pages read by each person by building from the number of pages read by Dayja.
Dayja read 84 pages
Luis read 75% more pages than Dayja and this is equal to:
84 + 84 × 75/100
84 + 84 × 0.75
84 + 63
= 147 pages.
Dayja read 75% more pages than Michael.
Believing that Michael read x number of pages.
84 = 175 ÷ 100 × x
8400 = 175x
x = 8400/175
x = 48
So, Michael read 48 pages.
Altogether we will have, 84 + 48 + 147 pages.
= 279 pages.

There are a total of 54 men.
Let's take x new men who joined the club, then according to the question (22-x) new women who joined the club.
[(98 × (5 ÷ 5 + 9)) + x ÷ [(98 × (9 ÷ 5 + 9)) + (22 - x)] ÷ [(98 × (9 ÷ 5 + 9)]= 9 ÷ 11
[(98 × (5 ÷ 14)) + x ÷ [(98 × (9 ÷ 14)) + (22 - x)] ÷ [(98 × (9 ÷ 5 + 9)]= 9 ÷ 11
[35 + x] ÷ [63 + (22 - x)] = 9 ÷ 11
11 × (35 + x) = 9 × (85 - x)
385 + 11x = 765 - 9x
11x + 9x = 765 - 385
20x = 380
x = 19.
Therefore, 19 new members have joined the club.

Answer:
19
Step-by-step explanation:
Originally there are 98 members
Ratio of men to women = M:W = M/W = 5/9
The ratio of men to total number of members = M/(M + W) and this should be the same as 5/(5+9) = 5/14
Since 5/14 th of the total membership of 98 members is the number of men,
Actual number of men
= 98 x (5/14)
= 35
After 22 members join the club, the total club membership is 98 + 22 = 120
The new ration M/W = 9/11
Actual number of men members
= 120 x 9/(9+11)
= 120 x 9/20
= 6 x 9
= 54
Increase in the membership of men = 54 - 35 = 19

a rectangular piece of metal is 10 in longer than it is wide. squares with sides 2 in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 671 in, what were the original dimensions of the piece of metal?
The length and width of the piece of metal are 28 and 18 inches respectively.
What is volume?
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
Dimension of the rectangle;
Width(w)
Length,L= 10 + w
volume of the box = length * width * height
Dimension of the box;
length of box, (x + 10) - 4 = x + 6
width of box,(x - 4)
height of box = 2
The volume of the box is 672 in³;
⇒V=lwh
⇒V=2 (x -4)( x + 6)
⇒672 in³ = 2x² + 4x - 48
⇒2x² + 4x - 720 = 0
⇒x^2 + 2x - 360 = 0
⇒(x +20)(x - 18) = 0
⇒x = 18
⇒x=-20 (value of the dimension will not be negative.
The width of an original piece of metal is;
Width,w=18 inches
length,l= 28 inches
Hence. the length and width of the piece of metal are 28 and 18 inches respectively.

f(x) = 3 x + 1 and g (x) = 2x - 3. find g (f(x))
Answer:
6x -- 1
Step-by-step explanation:
To Solve for g(f(x)), bear in mind
f(x) = 3x + 1
g(x) = 2x -- 3
g(f(x)) = 2x -- 3. (Calm down right?)
Let x = f(x).
if you recheck g(x) = 2x -- 3 so we got the (x) from it (do you get?)
g(f(x)) = 2(3x + 1) -- 3
g(f(x)) = 6x + 2 -- 3
g(f(x)) = 6x -- 1
#AllonGod
Answer:
Step-by-step explanation:
To find g(f(x)), first, understand that this means we are going to use the function of f(x) where the x would be in g(x).
1. First, identify the x in g(x) and replace it with the function of f(x)
g(x)=2x-3; so g(f(x))= 2(3x+1) -3
2. Simplify the equation by distributing the 2 and combining like terms.
2*3x=6x and 2*1=2, so we are left with 6x+2-3. After, just do 2-3 to end up with
g(f(x))=6x-1

(x^2-9/x+4=3-(x-3)/x+4
Answer:
x = 2.579248
Step-by-step explanation:
x^2 - 9/x + 4 = 3 - (x - 3/x) + 4
a) Multiply both sides by x.
x^3 + 4x - 9/x = 6x + 3
b) Multiply both sides by x.
x^4 + 4x^2 - 9x = 6x^2 + 3x
x^4 + 4x^2 - 9x - (6x^2 + 3x) = 6x^2 + 3x - (6x^2 + 3x)
x^4 - 2x^2 - 12x = 0
x(x^3 - 2x - 12) = 0
x = 0 or x^3 - 2x - 12 = 0
x = 0 or 2.5792479999999998

Area of a triangle with a vertical height of 1/2 m and base of 1/4 m.
Answer:
1/16 squared meters
Step-by-step explanation:
The formula to find the area of a triangle is [tex]\frac{Base * Height}{2}[/tex]
We can form an equation if we substitute the values (base and height).
[tex]\frac{1/2*1/4}{2}[/tex]
1/2 * 1/4 = 1/8
and [tex]\frac{1/8}{2}[/tex] = 1/16
Therefore, the area of a triangle with a vertical height of 1/2 m and a base of 1/4 m is 1/16 meters squared.

The area of the triangle for the given parameter is 12.4 squared cm.
How to calculate the area of the triangle?
In mathematics, the area of the triangle is classified into three forms isosceles, scalene and equilateral. Depending upon the sides of the triangle, it is classified. That means, when the two sides are equal then the triangle is isosceles triangle.
According to the question, the given parameters for the calculation of the area of the triangle is as written below:
Side of the triangle(a) = 5.2 cm. Angle of a triangle(B) = 67°.
Using standard formula for the area of the triangle, we get:
Area of the triangle = (1/2)(5.2)(5.2)sin(67°) = 12.4384 = 12.4 squared cm.
Hence, the area of the triangle for the given parameter is 12.4 squared cm.

D. axis of symmetry: x=-2
Vertex: (-2,-6)
The vertex and the axis of symmetry are (-2, -6) and x = -2, respectively
How to determine the vertex and the axis of symmetry?The equation of the function is given as
f(x) = x^2 + 4x - 2
The above equation is a quadratic equation
Next, we plot the equation on a graph (see attachment)
The vertex of the graph is the minimum or the maximum of the graph
In this case, we have
Minimum= (-2, -6)
This means that
Vertex = (-2, -6)
The axis of symmetry is the x-coordinates of the vertex
So, we have
x = -2
Hence, the vertex is (-2, -6) and the axis of symmetry is x = -2
