Answer:
m=3/19
Step-by-step explanation:
Find the slope between 2 points:
(x1,y1)=(-14,-7)
(x2,y2)=(5,-4)
First you would use the slope Formula:
m= y2,-y1/x2,-x1

You have $20 and earn $0.75 for each cup of orange juice you sell. Write an equation that represents the total amount A (in dollars) you have after selling j cups of orange juice.
Answer:
A= 20 + 0.75*j
Step-by-step explanation:
Giving the following information:
You have $20 and earn $0.75 for each cup of orange juice you sell.
To calculate the total amount of dollars (A), we need to use the following formula:
A= 20 + 0.75*j
j= number of cups
For example, for 15 cups:
A= 20 + 0.75*15
A= $31.25
Add a grocery store bananas cost $.90 each and oranges cost $.80 each Ava has $15 to spend if Ava wants to buy an equal amount of bananas and oranges at most how many of each can't you buy
Answer:
9
Step-by-step explanation:
We are given that
Cost of each banana=$0.90
Cost of each orange=$0.80
Ava have total money=$15
We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.
Let x be the number of each.
According to question
[tex]0.9x+0.8x=15[/tex]
[tex]1.7x=15[/tex]
[tex]x=\frac{15}{1.7}[/tex]
[tex]x=8.8\approx 9[/tex]
[tex]x=9(approximately)[/tex]
Hence, number of banana bought=9
Number of oranges bought=9

A room has an area of 1824 square feet. How many people could fit if they were spaced 14 feet apart?
Answer:
260 people would fit if they were spaced apart

There are 16 people on the bus. Some adults and some are children. There are more adults than children. Write down different ratios of adults to children that might be on the bus.
Answer:
11 : 59 : 713 : 3Step-by-step explanation:
There are more adults than children so the ratios made have to depict this.
These ratios should add up to 16.
Three different ratios:
11 adults : 5 children
9 adults : 7 children
13 adults : 3 children
The above will all add up to 16 and show more adults than children.
The different ratios of adults to children that might be on the bus is;
14 : 2, 13 : 3, 12 : 4, 11 : 5, 10 : 6, 9 : 7
We are given;
Number of people on the bus = 16The people on the bus consist of adults and children.
We are told that;
There are more adults than children.Thus, the different possibilities for ratio between
adults and children will be 2 numbers that add up to 16 which must not be equal. Thus, we have;
14 : 2
13 : 3
12 : 4
11 : 5
10 : 6
9 : 7

mr. Murphy's Megan graph to show his class the amount of water person consumes from food and beverages over time.
a person consumes 12 gallon of water each day (i already answerd this part)
(this part is the one im asking about )
complete the equation to show the relationship between X the number of days and Y the amount of water consumed
Y = ? X
Answer:
y = 12x
Step-by-step explanation:
From the question, we are told that a person consumes 12 gallons of water each day
Now, we want to complete an equation
From the question, x is the number of days and y is the amount of water consumed
Thus, mathematically, we have the equation as;
y = 12x
since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on
So the amount of water depends on rate number of days
Answer:
12

how do i figure out prime numbers
Answer:
You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

Solve for c.
40 + 2 < 10
A
AL
s
Answer:
c < 2
Step-by-step explanation:
We have an inequality and are asked to solve for the variable "c."
4c + 2 < 10
To solve for c, we need to get it by itself, isolate it in every way possible.
4c + 2 < 10
Subtract 2 from both sides :
4c < 8
Now before we move on, take this into consideration, sometimes the inequality sign can be switched but under one condition. And that is when you divide both sides by a negative, since we are not dividing by a negative, no switch of the sign is needed.
Divide 4 from both sides to get c alone :
c < 2

When a number is increased by 5.5%, the result is 60. What is the original number to the nearest tenth?
Answer: 56.9
Step-by-step explanation:
Let the original number be denoted by x.
We are informed that when the number is increased by 5.5%, the result is 60. This can be represented by:
x + (5.5% of x) = 60
x + (0.055 × x) = 60
x + 0.055x = 60
1.055x = 60
x = 60/1.055
x = 56.9
The original number is 56.9

Use y=mx+b and m=y2-y1/x2-x1 to find formula
m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6
y=6x+b
9=6(5)+b
