What is the constant of proportionality? What does it represent?
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. It can represent a number of things such as; increase or decrease in a set of numbers, a (x,y) point on a graph, or it can just be shown in a table to show rate change.

The line L is a tangent to the circle x2 + y2 = 45 at the point (-3, 6).
The line L crosses the x-axis at the point P.
Work out the coordinates of P.
Answer:
The point P is (-15,0).
Step-by-step explanation:
We need to find the slope of the line L to get the coordinates of P.
We know that L is tangent to the circle at point (-3, 6), which means L is perpendicular to the radius of the circle (a line between the origin (0,0) and the tangent point (-3,6))
So let's find the slope or the radius.
[tex]m_{R}=\frac{6-0}{-3-0}[/tex]
[tex]m_{R}=-2[/tex]
Now, we know that if two lines are perpendiculars their slopes follow the rule:
[tex]m_{L}=-\frac{1}{m_{R}}[/tex]
[tex]m_{L}=\frac{1}{2}[/tex]
Knowing the slope of L we can find the equation of this line. The slope-intercept equation of a line is:
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{2}x+b[/tex]
Using the point (-3,6) we can find b.
[tex]6=\frac{1}{2}(-3)+b[/tex]
[tex]b=\frac{15}{2}[/tex]
The line equation will be:
[tex]y=\frac{1}{2}x+\frac{15}{2}[/tex]
The point P has only an x-coordinate value (x,0)
So we have:
[tex]0=\frac{1}{2}x+\frac{15}{2}[/tex]
[tex]x=-15[/tex]
Therefore, the point P is (-15,0).

Determine the value of x for the following isosceles triangle.
Given :
▪︎This triangle is an isosceles triangle.
▪︎Measure of one of its legs = 6 inches
▪︎Measure of its equivalent leg [tex] = \tt \frac{x}{9} [/tex] inches
▪︎Measure of its base [tex] = \tt \frac{5}{2} [/tex] inches
Which means :
[tex] =\tt 6 = \frac{x}{9} [/tex]
[tex] =\tt \frac{6}{1} = \frac{x}{9} [/tex]
[tex] =\tt 6 \times 9 = x \times 1[/tex]
[tex]\hookrightarrow\color{plum}\tt 54 = x[/tex]
Let us check whether or not we have found out the correct value of x by placing 54 in the place of x :
[tex] =\tt 6 = \frac{54}{9} [/tex]
[tex] = \tt6 = 6[/tex]
Since the Left Hand Side of the equation is equivalent to the Right Hand Side of the equation, we can conclude that we have found out the correct value of x.
▪︎Therefore, the value of x = 54
The point Q has coordinates (2,3)
The point R has coordinates (a, b)
A line perpendicular to QR is given by the equation 5x + 2y = 9
Find an expression for b in terms of a. W
Answer:
b= (2a+11)/5
Step-by-step explanation:
5x + 2y = 9
2y=9-5x
y= 9/2 - 5x/2
slope, m1= -5/2
for perpendicularity, m1 × m2 = -1
slope for QR= m2=
[tex] = - 1 \div \frac{ - 5}{2} = - 1 \times \frac{2}{ - 5} = \frac{ - 2}{ - 5} = \frac{2}{5} [/tex]
m2 is 2/5
[tex]qr = \frac{b - 3}{a - 2} [/tex]
[tex] \frac{2}{5} = \frac{b - 3}{a - 2} [/tex]
5(b-3)=2(a-2)
5b-15=2a-4
5b=2a-4+15
5b= 2a+11
[tex]b = \frac{2a + 11}{5} [/tex]
An expression for b in terms of a is b = (2a + 11)/5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given an equation of a line 5x + 2y = 9 ⇒ 2y = - 5x + 9 ⇒ y = (-5/2)x + 9/2.
So, the slope of the line parallel to QR is the slope negative reciprocal of (-5/2) which is (2/5).
We know slope m = (b - 3)/(a - 2).
∴ (2/5) = (b - 3).(a - 2).
2(a - 2) = 5(b - 3).
2a - 4 = 5b - 15.
2a + 11 = 5b.
b = (2a + 11)/5.

Ashton just launched a new business page on social media. After one month, she has 35 followers.
She decides to take a course that promises to triple her number of followers each month for 6
months. After 7 months, how many followers will Ashton have if this is true?
Answer:
122.5
Step-by-step explanation:
If it triples her followers per 6 months then it gives her half of her followers in one month. So 35 times 3.5 which is 122.5
After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.
What is modelling ?Modelling is the process of creating a mathematical representation of a real-world scenario to make a prediction or provide insight.
We have,
Number of followers [tex]=35[/tex]
So, Every month increase is triple i.e. [tex]3[/tex] times for next [tex]6[/tex] months.
So,
According to the question,
Every month increase [tex]=\ 3\ *\ Current\ Follower[/tex]
So,
Followers after [tex]7[/tex] months [tex]= 35*(3)^6[/tex]
Because followers are increasing at the rate of three times per month,
So,
Followers after [tex]7[/tex] months [tex]= 35*(3)^6=25,515[/tex]
Hence, we can say that After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.

A textbook store sold a combined total of 435 psychology and sociology textbooks in a week. The number of sociology textbooks sold was 61 less than the number of psychology textbooks sold. How many textbooks of each type were sold?
Answer:
248 psych books, 187 soc books.
Step-by-step explanation:
x psych books were sold
x-61 soc books were sold
Total books was 435.
So -
x+x-61 = 435
2x-61 = 435
2x = 496
x = 248.
so x-61 = 187 and
248+187 = 435.
248 psych books, 187 soc books.

What is inequality?The phenomenon of unequal or unequal distribution of resources and opportunities among members of a given society is referred to as inequality. In different contexts and for different people, the concept of inequality may mean different things. In addition, there are distinct but interconnected economic, social, and spatial dimensions to inequality. The disjuncture between the moral ethics of equity and social justice, on the one hand, and the normative concept of "deservingness," on the other, adds complexity to debates about inequality.
Given equation of inequality for basket ball and soccer ball
y ≥ 2 + x
where x is the number of basketballs, and y is the number of soccer balls on display,
situation says the second number must be at least 2 more than the first number. Also, we are dealing with basket ball and soccer ball, so we won't have negative numbers (Choice E is out) or fractions (Choice B is out).
for choice A: x = 4 and y = 10 (10 is 6 more than 4)
for C: x = 14 and y = 12 (12 is 2 lee than 14 it is not correct)
for D: x= 10 and y = 12 (12 is 2 more than 10)

For the first two use the formula [tex]A^2 + B^2 = C^2[/tex]
[tex]15^2 + 36^2 = C^2(unknown)[/tex]
Calculate 15 x 15 + 36 x 36 = 1521
Now its
1525 = C^2
Fins the squeare root of 1521 whitch is 39
and square c^2 as well whitch make it C^1 or simple C
This give us a final anwser of the missing side
39 = C
Second triangle
For this the formual is different since we are not finding the lenght of the hypotunus (C), we know this becauee the missing angle is met my a 90 digree angle.
Here the equasion is C^2 - A^2 = B^2
WE will it in again
15^2 - 9^2 = B^2
Calaulate 15 x 15 - 9 x 9 = 144
Now its 144 = B^2
Again we find the square root for each side
Square root of 144 is 12
and Square root of B^2 is Simpley B
We put in togethe to find the final anwser whitch is
12 = B
For the last two it is simple
All angles of a triangle added together must always equal 180 degrees
So it the two side are 75 and 32 we add them (75+32) to get 107
Now we just subtract that amount (107) form 180 to get the third missing angle. 180 - 107 = 73
Here the missing angle is 73
One way to know if this is correct is to add all side and see if it equaels 180
75 + 32 + 73 = 180
For the second question it seems to be exactly the same as the first in the photo so the anwser would also be 73.
Hope this helps! :)

-x = 12
X = 48
What was Mai's error?
Answer: Please see explanation column for answer.
x= -36
Step-by-step explanation:
Step 1
from the attachment, Mai's solving is given as
1/3 (1/2x- 9) = 1/2 (x+18)
1/6x-3= 1/2x+9
1/4x-3=9
1/4x=12
x=48
Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.
Solving correctly, we have that
1/3(1/2x-9) = 1/2(x+18)
1/6x -3= 1/2x+ 9
taking like terms to like terms
1/6x-1/2x= 9+3
(1-3)/6x= 12
-2/6x= 12
-1/3x= 12
multiplying both sides by -3
-1/3x X -3 = 12 X -3
x= -36
