Answer:
See Below
Step-by-step explanation:
We are given 3 equations.
3x + 8
5x - 20
and
5x + 4y
First lets solve for x using the first two
3x + 8 = 5x -20
Move the variables to one side
3x + 8 = 5x -20
-3x -3x
8 = 2x -20
+20 +20
28 =2x
28/2 =2x /2
14 = x
Now we have x = 14
Lets plug this into the second equation to solve for the angle
3(14) + 8
42 + 8 = 50
5(14) - 20
70 - 20 =50
Now, lets plug the x and the angle into the third equation to find y
5 (14) +4y = 50
70 + 4y = 50
-70 -70
4y = -20
4y/4 = -20/4
y = -5
So now we have:
x = 14
y = -5
and the angle = 50
Hope this helps!
Answer:
Cost for 13 rides: $92
Cost for r rides: I am guessing it would be 40+4r
Step-by-step explanation:
If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
General vertex form:
![y = m(x − a)² + b \: with \: vertex \: at \: (a, b)](https://tex.z-dn.net/?f=y%20%3D%20m%28x%20%E2%88%92%20a%29%C2%B2%20%2B%20b%20%20%5C%3A%20with%20%20%5C%3A%20vertex%20%5C%3A%20%20at%20%5C%3A%20%20%28a%2C%20b%29)
Given :
![y = 2x² + 5x - 3](https://tex.z-dn.net/?f=y%20%3D%202x%C2%B2%20%2B%205x%20%20-%203)
Extract "spread factor" m
![y = 2( x² + \frac{5}{2} x) - 3](https://tex.z-dn.net/?f=y%20%3D%202%28%20x%C2%B2%20%2B%20%20%5Cfrac%7B5%7D%7B2%7D%20x%29%20-%203)
Complete the square
![y = 2(x² + \frac{5}{2}x + ( \frac{5}{4})²) - 3](https://tex.z-dn.net/?f=y%20%3D%202%28x%C2%B2%20%20%2B%20%20%5Cfrac%7B5%7D%7B2%7Dx%20%2B%20%28%20%5Cfrac%7B5%7D%7B4%7D%29%C2%B2%29%20-%203)
![- 2( \frac{5}{4})²](https://tex.z-dn.net/?f=%20-%202%28%20%5Cfrac%7B5%7D%7B4%7D%29%C2%B2)
Write as a squared binomial and simplify the constant
![y = 2(x + \frac{5}{4})² - 6 \frac{1}{8}](https://tex.z-dn.net/?f=y%20%3D%202%28x%20%2B%20%20%5Cfrac%7B5%7D%7B4%7D%29%C2%B2%20-%206%20%5Cfrac%7B1%7D%7B8%7D%20)
Re-write to match signs of standard general form:
![y = 2(x - ( - \frac{5}{4}))² \: + ( - 6 \frac{1}{8})](https://tex.z-dn.net/?f=y%20%3D%202%28x%20-%20%28%20-%20%20%5Cfrac%7B5%7D%7B4%7D%29%29%C2%B2%20%5C%3A%20%20%2B%20%28%20-%206%20%5Cfrac%7B1%7D%7B8%7D%29)
