Answer:
The function is non-proportional.
Step-by-step explanation:
If the function was proportional, when the number of hours spent riding the bicycle is equal to 0, the total cost of renting the bicycle would also be 0. In other words, the function would be proportional if y=0 when x=0. However, this is not the case.
[tex]y=15x+10[/tex]
Plug 0 into the equation as x
[tex]y=15(0)+10\\y=10[/tex]
When 1 bicycle has been rented for 0 hours, the customer still has to pay 10 dollars just for renting it. When x=0, y=10. This means that the function is non-proportional.
I hope this helps!

What are the slope, m, and the y-intercept, B, of a line that pases through the points (-2,1)and (8,-5)?
A. m=-5/3 and b=-7/3
B. m=-3/5 and b=-1/5
C. m=-3/5 and b=11/5
D. m=5/3 and b=13/3
Answer:
B. m= -3/5 and b= -1/5Step-by-step explanation:
Given points:
(-2, 1) and (8, -5)Slope is:
m = (y2 - y1)/(x2 - x1)m = (-5 - 1)/(8 - (-2)) = -6/10 = -3/5m = -3/5Use formula y = mx + b, substitute x = -2, y = 1, m = -3/5, find y-intercept b:
1 = (-3/5)*(-2) + b1 = 6/5 + bb = 1 - 6/5b = - 1/5Correct option is B.

Tyson brought a bag of coins into the bank to be counted. The bag contained only nickels and
dimes. There were a total of 220 coins and the total value of those coins was $15.50.
Use what you have learned about systems of linear equations to determine how many of the coin
were nickels and how many were dimes. Then, fill in the blanks below with your answer.
number of nickels is
number of dimes is
There will be 130 nickels and 90 dimes. 100 nickels is 5 dollars. 90 dimes are 9 dollars. And then there will be 30 left. 30 dimes isn’t 1.50$ bur 30 nickels is 1.50$ so you add the 30 to the nickels and it’ll be exactly 15.50$.

— 2y – Зу +8 = 8 — 5у – 12
Answer:
No Solution.
Step-by-step explanation:
Equality equation:
— 2y – Зу +8 = 8 — 5у – 12 (Given)
-5y + 8 = -4 - 5y (distributive property of equality)
-5y = -12 - 5y (subtraction property of equality)
= -12 (addition property of equality)
when you add 5y on both sides it cancels the 5y out, it's no solution.

how do i graph
y=-3/4x-1
Answer:
Start at -1 and go down 3 right 4,repeat. Then up 3 left 4 from -1, repeat.
Step-by-step explanation:
Answer:
So start at the y intercept which is -1 in this case becuase the point slope formula goes like
y=mx+b
m= slope
b= y-intercept
Y= Ranodm Y coordinate
X= Random X coordinate
You don’t have to worry so much about the x and Y, the main focus while graphing is the slope (m) and the y-intercept (y)
So -1 is the y-intercept so you go to -1 on the graph on the Y axis, it should be right below 0.
Now to make the points, the slope is -3/4
So a slope is written rise/run
Rise is going up and run is going right
-3 is the rise
4 is the run
Since the slope is negative (due to having a negative on 1 side)
We just do the opposite for the rise
Go down 3 and go to the right 4.
There you have it

p+ 9 = 2p-3
Answer:
One Solution
Step-by-step explanation:
p+9=2p-3
subtract 9 from both sides
p+9=2p-3
-9 -9
simplify
p=2p-12
subtract 2p from both sides
p=2p-12
-2 -2
simplify
-p= -12
divide both sides by -1
p=1

The length of a rectangle is 2 feet more than twice the width. The perimeter is 34 feet. What are the dimensions of the rectangle?
Answer:
5 feet
Step-by-step explanation:
5(2) + 2 = 12
12 x 2 = 24
5 x 2 = 10
10 + 24 = 34.

The dimensions of a rectangle are;
Length = 32 feet
Width = 15 feet
Here,
The length of a rectangle is 2 feet more than twice the width.
The perimeter of a rectangle is 34 feet.
What are the dimensions of the rectangle?
The two main dimensions of a rectangle are length (L) and width (W).
Now,
Let width of the rectangle is x
Then, length of rectangle is 2x + 2
The perimeter of a rectangle is 34 feet.
⇒ x + x + (2x + 2) +( 2x + 2) = 34
⇒ 6x + 4 = 34
⇒ 6x = 30
⇒x = 5
Hence, The dimensions of a rectangle are;
Length = 2x + 2 = 32 feet
Width = x = 15 feet

At the instant when the radius of a cone is 3 inches, the volume of
the cone is increasing at the rate of 9 pi cubic inches per minute. If
the height is always 3 times the radius, find the rate of change of the
radius at that instant.
Answer:
The rate of change of the radius of the cone when the radius is 3 inches is 0.[tex]\overline 3[/tex] inch/minute
Step-by-step explanation:
The given parameters are;
The radius of the cone = 3 inches
dV/dt = 9·π in.³/min
The height, h = 3 × Radius, r
The formula for the volume of a cone, V is V = 1/3×π×r²×h = 1/3×π×r²×3×r = π·r³
Therefore, we have;
dV/dt = dV/dr × dr/dt
dV/dr =3·π·r²
∴ dr/dt = dV/dt/(dV/dr) = 9·π/(3·π·r²) = 3/r²
When r = 3 inches, we have;
dr/dt = 3/r² = 3/(3²) = 1/3 inch/minute
The rate of change of the radius of the cone when the radius is 3 inches = 0.[tex]\overline 3[/tex] inch/minute

Step-by-step explanation:
a). Let the number of spoons = x
And number of forks = y
Total number of spoons and forks bought by Perry = 10
x + y = 10 --------(1)
Cost of one spoon = $5
Cost of one fork = $3
Therefore, total cost of x spoons and y forks = $(5x + 3y)
5x + 3y = 42 -------(2)
b). Now we can convert these equations into the slope-intercept form.
x + y = 10 ⇒ y = -x + 10
Table for input output values,
x 2 4 6
y 8 6 4
5x + 3y = 42

It will cost $215 for 2 guests to rent a cabin.
Step-by-step explanation:
$175+20(2)=$215
The total for both 2 guests are $390. Each time someone rents a cabin they have to add $20 more. $175+$20+$195. So $195 will the cost for a cabin for a guest. But we need 2 cabins which means to multiply $195 with 2 which gives you $390. So both 2 guests needs $390 to rent 2 cabin.
A department store buys 100 shirts at a cost of $700 and sells them at a selling price of $10 each. Find the percent markup
Answer:
30%
Step-by-step explanation:
The price for each shirt to buy is: $ 700/100 = $ 7 / each
Selling price is: $ 10 / each
So the difference between the selling and buying prices is: $ 10 - $ 7 = $ 3
So 100 each, the interest is: $ 3 X100 = $ 300 => 30%

Part B: Explain your answer in words. (2 points)
9514 1404 393
Answer:
a) b = (1/2)/(2/3); b = 3/4
b) it takes 3/4 bucket to fill a barrel
Step-by-step explanation:
a) Apparently, the number of buckets and the number of barrels is proportional, so we can write an equation for b, the number of buckets to fill a barrel, as ...
buckets/barrels = b/1 = (1/2)/(2/3) . . . . the equation
Of course, b/1 = b, so we simply need to simplify the compound fraction to find the solution.
b = (3/6)/(4/6)
b = 3/4 . . . . the solution to the equation
__
b) The solution to the equation is the answer to the question. It takes 3/4 bucket of nuts to fill the barrel.
