The equation for slope is rise over run. Y is the rise and X is the run. The point equation is (y2-y1)/(x2-x-1) = slope.
Plugging in the numbers: (-4-1)/(-4-0) = 1.25
Answer:

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the amount of money, M, he has after he has done laundry “x” times?
A) M= 7.50x - 240
B) M= 240 - 7.50x
C) M= 7.50 - 240x
D) M= 240x - 7.50
Answers
Answer:
B
Step-by-step explanation:
x = the number of times he does laundry.
Let's say he does the laundry 5 times then x = 5.
Each time costs $7,50.
If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.
M stands for how much money he still has left from the 240 dollars.
If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'
Therefore, the correct answer is B (M = 240 - 7.50x).

Find the number of minutes Carla runs for each mile. Show your work using mathematics.
Answers
Answer:
Carla ran 0.1 miles per minute.
Step-by-step explanation:
To solve this, we need to use the distance formula.
The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.
d=rt
3=(r)(30)
Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.
3/30=(r)(30/30)
0.1=r
The rate is 0.1. Carla ran 0.1 miles per minute.
Marsha has $400 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have in total in 1 year?
Answers
The total amount in the account after 1 year will be $420
Based on the information given, the following can be deduced:
Principal = $400
Interest rate = 5%
Time = 1 year
Therefore, the simple Interest will be:
= PRT/100
= ($400 × 5 × 1)/100
= $2000/100
= $20
Therefore, the amount will then be:
= Principal + Interest
= $400 + $20
= $420
Therefore, the total amount is $420

Jon is training for a bike race and is attempting to improve his average speed. With his old trainer, Jon averaged a pace of 20 MPH. With his new trainer, he rode at an average speed of 22 MPH. By what percent did his average speed increase?
Answers
Answer:
Jon is now 10% faster.
Step-by-step explanation:
Since Jon's average speed was 20 MPH and his new average speed is now 22 MPH, we can see that his speed increased by 2 MPH. Now we know that, we would now do 2÷20 = .1
10% is the percent form of 0.1

Paul
y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
Answers
Answer:
Tim's with a y-intercept of $2,780
Step-by-step explanation:
To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.
Step 1. Get y by itself by adding 1,400 to both sides.
y-1400 + 1400 = y
56(x+26) + 1400 = 56(x+26) + 1400
New equation y = 56(x+26) + 1400
Step 2. Distribute 56(x+26)
56(x+26) = 56 * x + 56 * 26 = 56x + 1456
New equation y = 56x + 1456 + 1400
Step 3. Simplify.
y = 56x + 2856
Paul's y-intercept would be 2856 because when y=0 x=2856
To Find Tim's y-intercept, subtract 225 * 8 from 4580.
225 * 8 = 1800
4580 - 1800 = 2780

F(x)=
Answers
Considering the zeros, the graph for the sinusoidal function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.The sine function is given by:
[tex]F(x) = A\sin{Bx}[/tex]
In which:
The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].In this problem:
We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:[tex]\frac{2\pi}{B} = 14[/tex]
[tex]B = \frac{2\pi}{14}[/tex]
[tex]B = \frac{\pi}{7}[/tex]
Thus:
[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]
Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

Jeanette earn $33 in 8 hours. At the rate, how much would she earn in 5 hours?
Answers
Answer:
If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is

Write your answer as a whole number.
centimeters per minute upstream
Answers
Answer:
It would approximately be 3.73 m/h
Step-by-step explanation:
0.8 mins is 48 seconds
I then divided 8000 by 48 seconds to see how many cm it traveled per second.
It traveled 166.666666667 cm per second
I then converted cm to feet
so it was 5.468066491699474 feet per second
I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.
Then I multiplied it by 60 so it was 0.06213711922 miles per minute.
Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.
I rounded it to the nearest hundredth making it 3.73 m/h
