Answer:
y=3/4x
Step-by-step explanation:
Better known as C.
I chose this answer choice because I pulled up a graphing calculator and the result I got was y=3/4x (aka, C)
The equation that best represents the direct variation function is y = 3/4x; option C.
What is direct variation function?A direct variation function is a function in which the domain and range of a function varies directly.
The direct variation function contains the points (–9, –3) and (–12, –4)
Therefore, the equation that best represents the direct variation function is y = 3/4x.

whats transitive property
Answer:
It tells us that if A=B and B=C, then A=C. The transitive property of order uses the same idea, except with < or ">> signs instead of = signs
Step-by-step explanation:
Answer:
the transitive property states that: If a = b and b = c, then a = c. In other words, if a is related to b by some property, and b is related to c by the same property, then a is related to c by that property.

Philip made a total of 9 bracelets and necklaces from 120 inches of cord.
He used 8 inches of cord for each bracelet and 20 inches of cord for each necklace.
Use matrices to find the number of bracelets and the number of necklaces that Philip made.
number of bracelets=
number of necklaces=
Answer:
number of bracelets= 5
number of necklaces= 4
Step-by-step explanation:
* I don't know how to show a matrix with a keyboard so I'm just going to do two lines of brackets to represent the matrix.
b=bracelets
n=necklaces
[8 20 | 120]
[b n | 9 ]
You should put this into a graphing calculator:
[8 20 | 120]
[1 1 | 9 ]
Then use reduced row echelon form which equals:
[1 0 | 5]
[0 1 | 4]
The top line being the number of bracelets and the bottom line being the number of necklaces
Rodrigo wants to buy football for $22.50 and a pair of gloves for $15.50. If the sales tax rate is 6%, what will be the amount of sales tax on Rodrigo’s purchase?
Answer:
$2.28

Football: $22.50
Gloves: $15.50

[tex]7 \times 3 = 21[/tex]
There are 21 roses in bouquet.
What are Arithmetic operations?Arithmetic operations are the fundamentals of math. The majority of the fundamental operations that can be carried out on relations are addition, subtraction, multiplication, and division. During the course of the day, we use them almost constantly. We use mathematical operations every day to figure out the total revenue and expenses of the business, make budgets for the month or year, and measure distances.
Given
total roses = 49
divided equally in 7 friends
number of roses for each friend = 49 ÷ 7
number of roses for each friend = 7
roses combined by 3 friends = 7 + 7 + 7
roses combined by 3 friends = 21
Therefore, roses in bouquet is 21.

Bryson is jogged at a constant rate of constant speed he starts a timer when he is 20 feet from his starting position. after 5 seconds, Bryson is 80 feet from his starting position. write a linear equation in slope-intercept form to find the distance d of bryson from his starting position after t second
Answer:
d = 4t + 60
Step-by-step explanation:
If Bryson jogged at a constant rate of constant speed and he starts a timer when he is 20 feet from his starting position. after 5 seconds, his speed will represent the slope of the required equation:
Speed = distance/time
Speed = 20 feet/ 5 secs
Speed = 4ft/s
Hence the slope of the equation is 4ft/s
Next is to get the intercept c
Standard equation that represents the expression is:
d = mt+c
d is the distance of bryson from his starting position
To get the intercept c, substitute d = 80, m = 4 and t = 5 into the equation as shown:
80 = 4(5) + c
80 = 20 +c
c = 80 - 20
c = 60
Get the equation:
Substitute m = 4 and c = 60 into the original equation
d = mt + c
d = 4t + 60
Hence a linear equation in slope-intercept form to find the distance d of bryson from his starting position after t second is d = 4t + 60

Sarah is cutting ribbons for a pep rally. The length of each ribbon needs to be 3.29 inches. If she needs 1,00 ribbons, what is the length of ribbon Sarah needs?
Answer:
3,290 inches of Ribbon
Step-by-step explanation:
Assuming that Sarah needs a total of 1,000 Ribbons we would simply need to multiply this total amount by the size of each individual Ribbon, which according to Sarah is 3.29 inches. This is because this would be like adding the size of each individual ribbon to get the total length. Like so...
1,000 * 3.29 = 3,290inches
Therefore, Sarah would need a total of 3,290 inches or
3,290 / 12 = 274.16ft of ribbon

A video game store sold 135 copies of a new release game in June. In July, they sold 108 copies of the same game. What is the percent decrease in the sales of this game from June to July?
percent decrease: decrease/old price * 100%
Subtract:
135 - 108 = 27
Fill into formula,
= 27/135 * 100%
= 1/5 * 100%
= 0.20 * 100%
= 20%
therefore, the percent decrease is 20%!

Mr joseph bought 9 pounds of fertilizer for his lawn he uses 2 2/3 pounds for his backyard and 1 2/9 pounds fo rdd hi front yard how much fert I'll lizer is left
Answer:
5 pounds
Step-by-step explanation:
Total pounds of fertilizer purchased purchased for lawn = 9 pounds
Amount used for backyard = 2 2/3 pounds
Amount used for front yard = 1 2/9
Amount of fertilizer left :
Total amount purchased - total. Amount used
Total amount used :
(amount used for backyard + amount used for front yard)
(2 2/3 + 1 2/9) = (8/3 + 11/9) = (24 + 11) / 9
= 36 / 9
= 4 pounds
Amount of fertilizer left :
Total amount purchased - total. Amount used
9 pounds - 4 pounds
= 5 pounds
Answer:
5 pounds
