Answer:
The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:
[tex]\mathbf{y=-\frac{2}{3}x+1}[/tex]
Step-by-step explanation:
We need to write equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3.
The equation for slope-intercept form is: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept.
We are given slope m = -2/3 and we need to find y-intercept i.e b to write equation of line.
Using point (3,-1) and slope m=-2/3 we can find y-intercept i.e b
[tex]y=mx+b\\-1=-\frac{2}{3}(3)+b\\-1=-2+b\\b=-1+2\\b=1[/tex]
So, y-intercept b = 1
The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:
[tex]y=mx+b\\\mathbf{y=-\frac{2}{3}x+1}[/tex]

A. 8
B. 4
C.8sqrt2
D. 8sqrt3
Answer:
The value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]
Option C is correct.
Step-by-step explanation:
We need to find value of x
We are given Perpendicular = 8
Hypotenuse = x
and Ф= 45°
Using trigonometric identity
[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}[/tex]
Putting values and finding x
[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}\\sin \ 45^o=\frac{8}{x}\\\frac{1}{\sqrt{2} }= \frac{8}{x}\\\frac{1}{\sqrt{2} }x=8\\x=8\sqrt{2}[/tex]
So, the value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]

The points in the table lie on a line. Find the slope of the line.
Answer:
4 !
Step-by-step explanation:
Using the slope formula, you can take two of those sets of points to find the slope! i used the first two.
(-2, -10) and (-1, -6)
[tex]m= \frac{-6 - -10}{-1 - -2} = \frac{4}{1} = 4[/tex]
So the slope is 4!

Calculate the circumference of a circle when the diameter is 5cm. Give your answer to 2
decimal places.
Answer:15.70
Step-by-step explanation:The formula for the circumference is 2πr. Plug-in the number provided into the formula, since diameter is double the radius you just divide the 5 by 2 to get 2.5.
So, 2π2.5=15.70
2 time π =6.28
6.28 time 2.5= 15.70

If the store currently charges a price of $50, then increases that price to $60, what happens to total revenue from shoe sales (calculate P X Q before and after the price change)
Answer:
Revenue will decreaseStep-by-step explanation:
Note: the question did not provide the quantity to work with, so we will assume some values, say quantity Q= 30
Generally, it is normal for the revenue to decrease when the price of a commodity increase, this is so that buyer will have to react to adjust to the change in price.
When price increase from $50 to $60, the total revenue will decrease
let say the quantity Q1=30 , and the new quantity after price increase is Q2=20
1. The revenue PxQ before price change will be
PxQ= P1xQ1=50*30
PxQ= $1500
1. The revenue PxQ after price change will be
PxQ=P2xQ2= 60*20
P2xQ2= $1200
This clearly shows that based on the assumed data, the total revenue will drop from1500 to 1200, a total of $300 in a decrease

Kadence reads 8 pages in her book every 30 minutes. How many pages will she read in 6 hours?
A. O 84 pages
B.O 96 pages
C.O 240 pages
D. O 48 pages
Answer:
96 pages

This is because she reads 16 pages per hour so we just multiply 16 by 6 hours. And we get 96 pages.
Answer:
B. 96 pages
Step-by-step explanation:
8 pages in 30 minutes.
16 pages in 60 minutes. ( 8 x 2 = 16 pages)

Two factory workers win the in-house raffle with a prize of £240. Monika and Robert share the prize money in a ratio of 3:5. How much does Monika get?
Answer:
Monika gets £90
Step-by-step explanation:
Let us use the ratio method to solve this question
∵ Monika and Robert are Two factory workers
∵ They win the in-house raffle with a prize of £240
∵ Monika and Robert share the prize money in a ratio of 3: 5
→ That means the total of the ratio is equivalent to the value of the prize
∵ The total of the ratio = 3 + 5 = 8
→ By using the ratio method
→ Monika : Robert : Total
→ 3 : 5 : 8
→ x : y : 240
→ By using the cross multiplication
∵ x × 8 = 3 × 240
∴ 8x = 720
→ Divide both sides by 8
∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{720}{8}[/tex]
∴ x = 90
∵ x represents the share of Monika
∴ Monika gets £90

The inverse of the function is:
f^-1(x) = {-1, 0, 1, 2} corresponding to x = {-2, 3, 8, 13}
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the inverse of the function, we need to switch the x and y variables, and then solve for y.
So, we start by writing the function in terms of y:
y = f(x) = {-2, 3, 8, 13} corresponding to x = {-1, 0, 1, 2}
Now we switch the x and y variables:
x = f(y) = {-2, 3, 8, 13} corresponding to y = {-1, 0, 1, 2}
Next, we solve for y:
For x = -2, y = -1
For x = 3, y = 0
For x = 8, y = 1
For x = 13, y = 2
Therefore,
The inverse of the function is:
f^-1(x) = {-1, 0, 1, 2} corresponding to x = {-2, 3, 8, 13}

3. Jin purchased 7 tacos for $18.55. How much will he pay for 15 tacos?
Jin (WWH) spends 18.55 for every 7 tacos he gets. That means he spends 18.55÷7 for every taco he gets.
18.55÷7 = 2.65
Now you need to find how much he spends for 15 tacos. If one taco is 2.65, you need to multiply 15 by 2.65 to find the price for 15 tacos.
2.65×15=39.75.
Jin will have to pay $39.75 for 15 tacos.

It's the 11th day of autumn and the first leaf has fallen! If the number of leaves on the ground is tripling with each passing day, what is the total number of leaves that have fallen to the ground by the end of the 24th day of autumn
Answer: 1,594,323
Step-by-step explanation:
No of leaves which falls daily on the first day = 1
No of days leaves falls = 14 days.
Solution:
No of leaves of day 1
= 1.
No of leaves on day 2
= 1*3
= 3
No of leaves of day 3
= 3*3
= 9
No of leaves of day 4
= 9*3
= 27
No of leaves on day 5
= 27*3
= 81
No of leaves on day 6.
= 81*3
= 243.
No of leaves of day 7
= 243*3
= 729
No of leaves on day 8
= 729 * 3
= 2187
No of leaves on day 9
= 2187 *3
= 6561
No of leaves on day 10
= 6561 * 3
= 19683
No of leaves on day 11
= 19683 * 3
= 59049
No of leaves on day 12
= 59049 *3
= 177147
No of leaves on day 13
= 531441
No of leaves on day 14
= 531441 * 3
= 1,594,323.
The number of leaves that would be on the ground on the 24th day of autumn would be 1,594,323
