One of your friends gives you $10 for a charity walkathon. Another friend gives you an amount per mile. After 5 miles, you have raised $13.50 total. Write an equation in slope-intercept form that represents the amount y of money you have raised after x miles.
y=
Answer:
y = 0.70x- 10.00
Step-by-step explanation:
-- Since one friend gave you 10.00 ,subtractthis from the 13.50 to give you the amount earned by walking the 5 miles
-- 13.5-10.00 = $3.50
-- Since you walked 5 miles, divide by 5 to give you 0.70 per mile earned.
So, an equation that represents the amount of money earned is:
y = 0.70x- 10.00 . This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile and the intercept is $10.00 and represents the initial amount of money that you were given.

Which graph represents the function -2x - 5y = -10?
Please explain!!
Answer:
Graph J represents the function -2x-5y=-10
Step-by-step explanation
To find the answer you have to find the y and x-intercepts first. To find the x and y-intercept I came up with two equations; -5y=-10 and -2x=-10. I came up with these equations because I'm finding the intercepts, so I know I have to substitute x and y with 0 one at a time. To solve the first equation I just divided -5 from both sides and got y=2, so my first intercept is (0, 2). I solved the second equation by dividing -2 from both sides and got x=5 which means my second intercept is (5, 0). Now I graph the two points on a graph and connect the dots, which turns out to be graph J on your image.

Step-by-step explanation:
To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:
38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)

What is the answer to this fast smart people
Answer:
m<R = 106°
Step-by-step explanation:
Given,
m<R = (6x+10)°
m<S = (2x+5)°
m<T = (3x-11)°
Now,
6x+10°+2x+5°+3x-11° = 180°{the sum of angles of triangle is 180°}
or, 11x+4° = 180°
or, 11x = 180°-4
or, x = 176°/11
or, x = 16°
therefore, x = 16°
m<R = (6x+10)°
= 6×16°+10°
= 96°+10°
= 106°

How does the minimum or maximum value of a parabola relate to the vertex of the same parabola?
Answer:
The graph of a quadratic function is a U-shaped curve called a parabola. ... If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.
Step-by-step explanation:
please mark me brainlist
The relationship between the vertex and the minimum or maximum value of the parabola is given below.
What is a parabola?A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.
Let the vertex be any parabola is (x, y).
When the graph of the parabola opens up,
then the y-value of the vertex is the minimum value.
And when the graph of the parabola opens down,
then the y-value of the vertex is the maximum value.
Therefore, the explanation is given above.

(HELP! I HAVE NO TIME) At 2pm, a store had sold 15 packs of toilet paper. By 5pm, the store had sold 57 packs of toilet paper. What is the average rate of change?
[tex]\mathrm {Hey, there!}[/tex]
Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the percent rate of change.
Here is how we will do this problem:
First, Set up a ratio:
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
Next, we will divide. the ratio.
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
Convert the fraction to a decimal.
Fraction - 42/15
Decimal - 2.8
Make the decimal to a percent.
Decimal - 2.8
Percent - 28%
Add a zero to the 28.
Our answer is 280%
Answer:
14 packs per hourStep-by-step explanation:
2pm ⇒ sold 15 packs 5pm ⇒ sold 57 packsAverage rate of change = change in sale/ change in time
(57 - 15) / (5 - 2) = 42/3 = 14 packs per hourValerie bought a guitar at a sale price of S = 0.8g, where g represents the original cost of the guitar. Which expression shows the sale price in a way that emphasizes the percent discount that she received? A S = (1 + 0.8). B S= (1 +0.2) g C S= (1 - 0.8). D S = (1 – 0.2) g
Answer:
D S = (1 - 0.2)g
Step-by-step explanation:
The original price of the guitar was g.
She paid 0.8g.
0.8g = 0.80g = 80% of g
If she paid 80% of the price, that means the discount was 20%.
100% - 20% = 1 - 0.2
Subtracting 20% form the whole 100% of the price is the same as subtracting 0.2 from the whole price of 1.
Answer: D S = (1 - 0.2)g
