Julio's Rental Cars charges $150 plus an additional $0.50 per mile
traveled. Identify the following:
Rate of change:
y-intercept:
Equation
Step-by-step explanation:
Given that Julio's Rental Cars charge $150, along with the additional $0.50 per mile traveled:
The equation that represents the given values is: y = 0.50x + 150
Where:
y = Total cost of renting a car
x = Number of miles traveled
$0.50 = Rate of change
$150 = Y-intercept
Rate of change (explanation):The $0.50 is the rate of change (or the slope of the equation), which represents the increase in total cost for every additional x number of miles driven.
Y-intercept (explanation):The $150 is the y-intercept, which is the initial amount or flat fee that the company charges given the x = 0 number of miles driven.

What is slope of the line?
Hello there!
To find the slope of a line, we need to know at least two points contained in the graph of the line.
The slope [tex]m[/tex] of a line passing through the points [tex](x_0,~y_0)[/tex] and [tex](x_1,~y_1)[/tex] is given by the formula: [tex]m=\dfrac{y_1-y_0}{x_1-x_0}[/tex].
As we can see on the graph, two points contained on the line are [tex](-2,~0)[/tex] and [tex](3,~4)[/tex].
Using the formula above, we get that:
[tex]m=\dfrac{4-0}{3-(-2)}[/tex]
Subtract the values on both numerator and denominator of the fraction
[tex]m=\dfrac{4}{5}~~\checkmark[/tex]
This is the slope of this line we were looking for.

In 5 - 7 complete sentences, answer all of the following question. •Use this image to respond to the following prompt: •Is the slope of this line positive or negative? How do you know? •What is the y-intercept of this line? How did you find it? •What is the slope of this line? How did you find it?
Answer:
positive slope
(0,3)
slope = 2
Step-by-step explanation:
Slope of the given line is positive If the line is sloping upward from left to right, so the slope is positive (+).or if the angle made by the line to the x axis is < 90 it's slope is positive.
y-intercept of the line is (0,3)The y intercept is the point where the line crosses the y axis. At this point x = 0.slope of the line is 2slope = (y2 - y1) / (x2 - x1)lines passing through points (1,5) (0,3)
slope = (3 - 5) / (0 - 1)
= -2 / -1 = 2
- The line is positive because it is going upwards from the bottom left to the top right
- The y-intercept is positive 3
- It can be found by seeing where the line intercepts the y-axis when x = 0
- Written as a coordinate point of (0, 3)
- The slope of the line is 2
- It can be found by using "rise over run" which is the change in y divided by the change in x

A jet travels 4680 miles against the wind in eight hours and 5720 miles in the wind in the same amount of time what is the rate of the jet in still air and what is the rate of the wind
9514 1404 393
Answer:
jet: 650 mphwind: 65 mphStep-by-step explanation:
The speed against the wind is ...
4680 mi/(8 h) = 585 mi/h
The speed with the wind is ...
5720 mi/(8 h) = 715 mi/h
The speed of the airplane in still air is the average of these speeds:
(585 +715)/2 = 650 mi/h . . . speed in still air
The speed of the wind is the difference between the airplane speed and the speed in the wind:
715 -650 = 65 mi/h . . . speed of the wind
_____
Additional comment
If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...
p + a = with
p - a = against
If we average these, we get ...
((p +a) +(p -a))/2 = (with + against)/2
p = (with + against)/2 . . . . . . . the formula we used above

In how many ways can you create a two-element set where each element in the set is an positive integer less than 85
If the order of the elements matters, we will see that there are 6,972 different possible sets, if the order does not matter, we will see that there are 3,486 possible sets.
The possible elements of the set are positive integers less than 85, then the possible elements are: 1, 2, ..., 84
So we will have a set:
{n, m}
And we know that both n and m are numbers in the interval [1, 84] (we assume that n ≠ m and that order matters.}.
For the first element, we have a total of 84 options to choose.
For the second element, we have a total of 83 options (because we selected one already).
The total number of combinations is just given by the product between the numbers of options, so we have:
C = 84*83= 6,972
There are 6,972 different possible sets.
If order does not matter, then n and m permutations are irrelevant, then the number of combinations is given by C/2:
C/2 = 6,972/2 = 3,486
In this case, there are 3,486 possible sets.

The height of a tree, y, varies directly with the length of its shadow, x, by the equation y = kx. If a tree's height is 24 feet and its shadow is 9 feet long, then k
Answer:
k = 8/3
Step-by-step explanation:
Hi there!
y = kx
We're given that the height of the tree is 24 feet and the length shadow is 9 feet. Plug these into the equation:
24 = k(9)
k = 24/9
k = 8/3
Therefore, k = 8/3.
I hope this helps!
Now, we will substitute the given values into the equation.
[tex]\large\rm{y = kz}[/tex][tex]\large\rm{24 = k(9)}[/tex][tex]\large\rm{k = \frac{24}{9}}[/tex][tex]\large\rm{k = \frac{24÷3}{9÷3}}[/tex][tex]\large\rm\red{k = \frac{8}{3}}[/tex]Hence, k is 8/3.

Find the unknown value.
Answer:
30
Step-by-step explanation:
A simple way to find an unknown value in an equality with fractions is to cross-multiply:
How to cross-multiply:
1. Multiply the first numerator by the second denominator (or vise versa).
2. Multiply the second numerator by the first denominator(or vise versa).
3. Put these values into an equation, making them equal to one another.
4. Find the unknown value by solving the equation.
Now, using your problem, I will take you through the steps of cross-multiplying:
(The unknown value will be written as a variable x.)
(1.) 15 × 10 = 150
(2.) 5 × x = 5x
(3.) 5x = 150
Divide both sides of the equation by 5 to find the exact value of x.
[tex]\frac{5x}{5}[/tex] = [tex]\frac{150}{5}[/tex]
After dividing, the equation will show x = 30, which is the unknown value.

[tex] \frac{15}{ \boxed{}} = \frac{5}{10} [/tex]
[tex] \frac{15}{x} = \frac{5}{10} [/tex]

Sally can paint a room in 5 hours while it takes Steve 8 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer:
Sally does 1/5 of a room per hour.
Steve does 1/7 of a room per hour.
Together --> 1/5 + 1/7 = 12/35 rooms per hour.
The inverse is hours per room = 35/12
--------------
Parallel work is similar to parallel flow and parallel resistors.
----
PS 5*7/(5+7) = 35/12
Step-by-step explanation:
Answer: about 3 hours and 5 minutes
Step-by-step explanation:
Sally can paint [tex]\frac{1}{5}[/tex] of the room in an hour while Steve is able to paint [tex]\frac{1}{8}[/tex] in an hour.
To find how long it would take to paint the room together you add the two fractions together:
[tex]\frac{1}{5} + \frac{1}{8}[/tex]
To add or subtract fractions we find a common denominator and add the numenators:
[tex]\frac{1}{5} = \frac{8}{40}[/tex] [tex]\frac{1}{8} = \frac{5}{40}[/tex]
[tex]\frac{5}{40} + \frac{8}{40} = \frac{13}{40}[/tex]
The inverse of the fraction is hours per room = [tex]\frac{40}{13}[/tex]
[tex]\frac{40}{13}[/tex] = 3.077 = about 3 hours and 5 minutes.

Answer: 36 Pieces In The Entire Cake
Step-by-step explanation: Memo had 1/4 pieces of the total cake, so that means that there were four times the value of what Memo ate in the cake, plus what Molly ate. 12 - 4 = 8, 8 times 4 is 32, and 32 plus 4 (what Molly ate) is 36. Hope that helped!

Select the correct answer from the drop-down menu. Vectors u and v are perpendicular. ||u||=5sqrt2 units, and ||v||=6sqrt2 units. ||u + v|| ≈ units
Recall that ||x||² = x • x for any vector x, so
||u + v||² = (u + v) • (u + v)
||u + v||² = (u • u) + (u • v) + (v • u) + (v • v)
||u + v||² = ||u||² + 0 + 0 + ||v||²
||u + v||² = ||u||² + ||v||²
where u • v = v • u = 0 since u and v are perpendicular.
Then
||u + v||² = (5√2)² + (6√2)²
||u + v||² = 25•2 + 36•2
||u + v||² = 122
||u + v|| = √122

Find the equation of the line containing the points (-5, 6) and (2, 1).
Step-by-step explanation:
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 6)/(1 - 6) = (x + 5)/(2 + 5)
(y - 6)/-5 = (x + 5)/7
7(y - 6) = -5(x + 5)
7y - 42 = -5x - 25
5x + 7y = -25 + 42
5x + 7y = 17
