The value of the inequality equations are
a) 5040 < 8820
b) 15 > 2
c) -20 < -18
d) -1 < 1
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be A
a)
4<7 Multiply both sides by 7 , then by 6, then by 3, then by 10
The inequality equation is A
The value of A is 4 < 7
Multiplying both sides by 7 , we get
28 < 49
Multiplying both sides by 6 , we get
168 < 294
Multiplying both sides by 3 , we get
504 < 882
Multiplying both sides by 10 , we get
5040 < 8820
Therefore , the inequality equation remains the same.
b)
11>-2 Add 5 to both sides, then add 3, then add (-4)
The inequality equation is A
The value of A is 11 > -2
Adding 5 on both sides , we get
16 > 3
Adding 3 on both sides , we get
19 > 6
Adding -4 on both sides , we get
15 > 2
Therefore , the inequality equation remains the same.
c)
-4<-2 Subtract 6 from both sides, then 8, and then 2
The inequality equation is A
The value of A is -4 < -2
Subtracting 6 on both sides , we get
-10 < -8
Subtracting 8 on both sides , we get
-18 < -16
Subtracting 2 on both sides , we get
-20 < -18
Therefore , the inequality equation remains the same.
d)
-8<8 Divide both sides by -4, then by -2
The inequality equation is A
The value of A is -8 < 8
Dividing both sides by -4 , we get
2 > -2
The sign of the inequality relation changes when multiplying or dividing by a negative number
Now , dividing by -2 on both sides , we get
-1 < 1
So , The sign of the inequality relation changes when multiplying or dividing by a negative number
Therefore , the inequality equation first changes and reverts back to the original relation
Hence , the value of the inequality relations are
a) 5040 < 8820
b) 15 > 2
c) -20 < -18
d) -1 < 1

Step-by-step explanation:
as you wrote correctly, proportional relationships are in the form
y = mx
that means the line has to go through the origin (0, 0). otherwise it is in the form
y = mx + b
which is still linear but not proportional.
1a.
the rate of change is between 2 points A and B
(Yb - Ya)/(b - a)
in our case e.g. (4, 5.52) and (8, 11.04)
(11.04 - 5.52)/(8 - 4) = 5.52 / 4 = 1.38
when we use other points we get the same result. we see e.g. that when we double x (pounds), then also y (cost) is doubled.
the rate of change is 1.38.
this is also called the slope of the line.
b.
as mentioned in a., when we multiply x by a factor, then y is multiplied by the same factor. it also means that the function contains (0, 0) : for 0 pounds we pay $0.
c.
y = 1.38x
2a.
the slope is (as it is the same as the rate of change) the ratio of (y coordinate change / x coordinate change) when going from one point on the line to another.
we try to find points with integer coordinates to do that.
I see e.g. (3, 4) and (6, 8).
x changes by +3 (from 3 to 6).
y changes by +4 (from 4 to 8).
so, the slope is +4/+3 = 4/3.
b.
the simplest indicator is that the line goes through the origin (0, 0), which it does.
c.
y = (4/3)x

How to find the coordinates of P and QThe coordinates of P and Q is found using the midpoint formula
The formula is of the form
X= (x₂ + x₁)/2
Y = (y₂ + y₁)/2
solving for P (X, Y) Using points A(2, -1), B(-3, 4)
(X, Y) = ((2 + -3)/2, (-1 + 4)/2)

What is a Cone?
A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the centre of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Given data ,
Let the two cones be A and B
Now , the smaller cone be A
The larger cone be B
The radius of the smaller cone is r = 8 cm
The height of the smaller cone is h = 20 cm
Now , the volume of the smaller cone V = ( 1/3 ) πr²h
Substituting the values in the equation , we get
Volume of cone A = ( 1/3 ) πr²h
Volume of cone A = ( 1/3 ) π x 8 x 8 x 20
Volume of cone A = 426.67 π cm³
Now ,
The larger flask is filled with height H = 20 cm
The radius of the larger cone is R = 14 cm
The height of the larger cone is H = 15 cm
Now , the volume of the smaller cone V = ( 1/3 ) πR²H
Substituting the values in the equation , we get
Volume of cone B = ( 1/3 ) πR²H
Volume of cone B = ( 1/3 ) π x 14 x 14 x 15
Volume of cone B = 980 π cm³
Therefore , the volume of the larger cone B is 980 π cm³

The probability that in tonight's game he misses for the first time on his 6th attempt = 0.2244
What is Probability?
A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The Probability that the basketball player made a foul shot = 0.66 or 60%

Just subtract the coefficients:
The coefficient of 10x is 10
The coefficient of 16x is 16
now do ten minus 16 (TIP: if you don't really like negative numbers, then an easy way of subtracting 10-16 is 16-10=6, then add the negative sign to 6; -6)
10 - 16 = -6

Step-by-step explanation:
When using the distributive property, the number outside the parentheses (12) is "distributed" to each of the values inside the parentheses. In other words, 12 will be multiplied by 3/4 and 2x:
12(3/4 - 2x)
12(3/4) - 12(2x) <----- so now we successfully got rid of the parenthesis. Next, simplify

How to find the volume of a composite object?a) Tennis ball is usually considered to be a sphere. The formula for volume of sphere is;
V = ⁴/₃πr³
where r is radius.
Since diameter = 2.6 inches, then radius; r = 2.6/2 = 1.3 inches
Thus;
Volume of each tennis ball;
V = ⁴/₃π(1.3)³
For the three tennis balls;
V₃ = 3(⁴/₃π(1.3)³)
V₃ = 8.788π
Volume of the cylindrical container = πr²h

Charmaine wanted to study how the area of a rectangle changes with the length if its width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then plotted the results and connected them with a line, as shown below. The graph shows the area (incm^2 ) versus the length (in cm).
Find the range and domain of the functions
The Range of the length of a rectangle having fixed width and area increasing linearly is = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers,
What is a rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.
Given:
The width of the rectangle is fixed, and the length is changing.
The line is formed when connected through the graph.
The area of the rectangle = [tex]length\times width[/tex]
So when the width is fixed, the area would increase linearly and directly proportional to length.
Calculate the range of function y = cx,
y = area as shown in the graph, x is the length, and width is constant c.
Range = {y ∈ R : c ≠ 0 or y ≠ 0}
Calculate the domain,
It can be any real number, as the area can't be negative.
Domain = All real numbers.
Therefore, Range = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers.

b. y = 1/4x - 9
c. y = -4x + 10

Since the line y = -1/4x + 10 has a slope of -1/4, the slope of the perpendicular line will be + 4/1 or 4. So any line with a slope of 4 will be perpendicular to y = -1/4x + 10.
