How do I write a slope intercept form from a graph
Answer:
Depending on your question
Step-by-step explanation:
For example if its (4,-2) you go 4 up because it's positive and 2 down because its negative. After, you connect those two coordinates and get your FINAL answer after.

Answer:
lol, u can still ask the question
Step-by-step explanation:
The equation 125 + 37.52x = y models the amount of money in your wallet Y is the total amount of dollars and x is the number of weeks from today.
Is the equation in slope intercept form? Explain
If you graphed this situation what would the slope represent? Explain
If you graphed this situation what would the y intercept be and what would it represent?
What units make sense for the slope?
The given equation is 125+37.52x=y, where y is the total amount of dollars and x is the number of weeks
This equation can be re-write as y=37.52x+125
Yes, this equation is in slope-intercept form y=mx+c having a slope, m=37.52 and the intercept, c=125.
Now, check the units,
In equation y=mx+c, units of all the three terms, i.e y, mx and c, are same.
As given that unit of y is dollar, so the unit of c is dollar and unit of [tex]mx[/tex] is also dollar.
As the unit of [tex]mx[/tex] is dollar, so the unit of m is dollar/unit of x.
As given that the unit of x is week, so the unit of m is dollar/week.
Therefore, the y-intercept, c= 125 dollars, and m=37.52 dollar/week.
The unit of the slope is dollars/week, so, the slope of the equation represents the rate of change of money in the wallet per week.
From the graph of the equation, y-intercept, c=125 dollars, is the value of y at x=0 which is the initial amount of money in the wallet.

solve the following equation 5a-4>2a+8
Answer:
4
Step-by-step explanation:
Simplifying
5a + -4 = 2a + 8
Reorder the terms:
-4 + 5a = 2a + 8
Reorder the terms:
-4 + 5a = 8 + 2a
Solving
-4 + 5a = 8 + 2a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
-4 + 5a + -2a = 8 + 2a + -2a
Combine like terms: 5a + -2a = 3a
-4 + 3a = 8 + 2a + -2a
Combine like terms: 2a + -2a = 0
-4 + 3a = 8 + 0
-4 + 3a = 8
Add '4' to each side of the equation.
-4 + 4 + 3a = 8 + 4
Combine like terms: -4 + 4 = 0
0 + 3a = 8 + 4
3a = 8 + 4
Combine like terms: 8 + 4 = 12
3a = 12
Divide each side by '3'.
a = 4
Simplifying
a = 4

~AnonymousHelper1807. Write the exponential function modeling an initial population of 67,000 and a relative growth rate of 1.7% per year. What population does your function project at the end of 37 years?
Answer:
In 37 years the population will be 125,012
Step-by-step explanation:
Giving the following information:
Initial population (PV)= 67,000
Growth rate (g)= 1.7%= 0.017
Number of years (n)= 37
First, we will establish the future value (FV) formula:
FV= PV*(1+i)^n
FV= 67,000*(1.017^n)
Now, for 37 years:
FV= 67,000*(1.017^37)
FV= 125,012
In 37 years the population will be 125,012
A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can't quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon. If he has $42.80 in his wallet, which equation represents the amount of money he may have after he sees Rita? |x – 42.80| = 12
Answer:
|x - 42.80| = 12
Step-by-step explanation:
The absolute value |x - a| = b means either x - a = b or x - a = -b
Let x represent the amount of money in the afternoon after he has either paid her back or she has paid him.
Given that he has $42.80 in his wallet and he either borrowed $12 from his friend Rita or she borrowed $12 from him. Therefore:
x = 42.80 + 12; or x = 42.80 - 12
Hence:
x - 42.80 = 12; or x - 42.80 = -12
|x - 42.80| = 12

A farmer has 300 feet of fence available to
enclose a 4500 square foot region in the
shape of adjoining squares, with sides of
length x and y. The big square has sides of
length x and the small square has sides of
length y. Find x and y.
UUUULTTUUL
x= ? feet
y = ? feet
Given :
A farmer has 300 feet of fence available to enclose a 4500 square foot region in the shape of adjoining squares, with sides of length x and y.
The big square has sides of length x and the small square has sides of length y.
To Find :
The value of x and y.
Solution :
From attached figure perimeter is given by :
x + x + x + y + y + y + ( x-y ) = 300 ft
4x + 2y = 300
2x + y = 150 ...1)
Now, area is given by :
A = x² + y²
x² + y² = 4500 ...2)
Putting value of y in equation 2), we get :
[tex]x^2 + ( 150 - 2x)^2 =4500\\\\x^2 + 4x^2 + 22500-600x =4500\\\\5x^2 -600x + 18000=0\\\\x^2 - 120x +3600=0\\\\x^2-2\times x\times 60 + 60^2 =0\\\\(x-60)^2 =0\\\\x = 60\ ft[/tex]
y = 150 - ( 2× 60 )
y = 30 ft
Therefore, the value of x and y is 60 ft and 30 ft respectively.
2x^2+15x=8
factor or solve as indicated, show all work.
please and thank u!
Answer: x= -8 or x = 1/2
Step-by-step explanation:
2x^2 + 15x = 8 Subtract 8 from both sides to let the whole equation equal 0
- 8 -8
2x^2 + 15x - 8 = 0 Now find two numbers that if you multiply them, their product will be -16 and their sum will be 15. An example is the numbers 16 and -1. 16 times -1 is -16 and 16 plus -1 is 15.
Rewrite the whole equation in this form,
2x^2 +16x - 1x - 8 = 0 Factor on the left side
2x ( x + 8) -1 (x + 8) = 0 Now factor out x + 8
(x + 8) (2x -1) = 0 Set each expression equal zero, because for the whole expression to equation to 0, either one of them or all of them have to equation zero.
x + 8 = 0 or 2x - 1 = 0
-8 -8 +1 +1
x = - 8 2x = 1
x = 1/2

Find the greatest common factor of 27 and 33.
Answer:
3
Step-by-step explanation:
26 and 33 both divisible by 3
The greatest common factor of 27 and 33 is 3.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to find the greatest common factor of 27 and 33.
GCF of twenty seven and seventy three.
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.
The factors of 27 are 1, 3, 9 and 27.
One , three , nine and twenty seven because 27 is divisible by the numbers.
The factors of 33 are 1, 3, 11 and 33.
One, three, eleven and thirty three because 33 is divisible by these numbers.
The highest common factor 27 and 33 is 3
Hence, the greatest common factor of 27 and 33 is 3.

If the mass of an object on Earth is 18kg what would the mass of the same object be on the Moon?
A. 18kg
B. 6kg
C. 108kg
D. 3kg
Answer: 18kg
Step-by-step explanation:
Mass is the amount of matter that a particular object has. First and foremost, we should note that a mass is not thesame as weight and that a mass is thesame everywhere.
In this scenario, since the mass of the object on Earth is 18kg, the mass of the same object on the Moon will slow be 18kg. The mass will not change.
