Answer:
41
Step-by-step explanation:
y = (4*5) + 21
y = 20 + 21
y = 41
Answer:
The y-intercept is (0,0)

There is a website u can use for graph problems. Look up graphing calculator and it is the first thing there. Hope this helps!
Answer: it would take 22 hours before you pay the same amount for both Garages.
Step-by-step explanation:
Let x represent the number of hours that you park at either Garage A or Garage B
Let y represent the total amount paid for x hours at Garage A
Let z represent the total amount paid for x hours at Garage B
Garage A charges $11 for the first 2 hours of parking there and then $3 per hour after the first 2 hours. This means that the total amount for x hours would be
y = 2 × 11 + 3x
y = 22 + 3x
Garage B charges $4 per hours. This means that the total amount for x hours would be
z = 4x
To determine the number of hours before the amount for both Garages becomes the same, we would equate y to z. It becomes
22 + 3x = 4x
4x - 3x = 22
x = 22
It would help to have the question. But I'll guess
![\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}} = ((x^{\frac 3 5})^{\frac 1 4}) }{ x} = x^{\frac 3{20}} x = x \sqrt[20]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E%7B%5Cfrac%203%205%7D%7D%7B%5Csqrt%7Bx%5E2%7D%7D%20%3D%20%28%28x%5E%7B%5Cfrac%203%205%7D%29%5E%7B%5Cfrac%201%204%7D%29%20%7D%7B%20x%7D%20%3D%20x%5E%7B%5Cfrac%203%7B20%7D%7D%20x%20%20%3D%20x%20%5Csqrt%5B20%5D%7Bx%5E3%7D)
2nd choice.
I forgot the explanation because I was so glad to have puzzled out the question.
The fourth root is the same as the 1/4 th power.
If we know x is positive
![\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E%7B%5Cfrac%203%205%7D%7D%7B%5Csqrt%7Bx%5E2%7D%7D)
We multiply the powers:
The one-twentieth power is the twentieth root. We bring the additional factor of x to the front.
![= x \sqrt[20]{x^3}](https://tex.z-dn.net/?f=%3D%20x%20%5Csqrt%5B20%5D%7Bx%5E3%7D)
Answer:
180 because fifty is half of a whole so 90*2=180
