Answer:
x = 0.3333333333
Step-by-step explanation:
Simplifying
42x = 14
Solving
42x = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '42'.
x = 0.3333333333
Simplifying
x = 0.3333333333
Answer:
y = 6x - 4
Step-by-step explanation:
Slope formula: y = mx + b
m = slope, found by figuring out the change in y over the change in x. A fancy way to say find the simplest rate of how far up it goes over how far right it goes. In this case, the line goes up 6 for every time it goes right one; 6/1. This can be simplified as 6.
b = y-intercept, meaning where the line crosses the y line. In this line, you can see that it crosses at -4.
Hope this helps!
90 divided by 4 is 22.5
22.5 multiplied by 22.5 is (506.25)
Look at their diameter and radius. if they are the same the circles are the same.
Step-by-step explanation:
Set the equation
![(x - 4) {}^{2}](https://tex.z-dn.net/?f=%28x%20%20-%204%29%20%7B%7D%5E%7B2%7D%20)
swap y and x
![(y - 4) {}^{2} = x](https://tex.z-dn.net/?f=%28y%20-%204%29%20%7B%7D%5E%7B2%7D%20%20%3D%20x)
![y - 4 = {x}^{2}](https://tex.z-dn.net/?f=y%20-%204%20%3D%20%20%7Bx%7D%5E%7B2%7D%20)
![y = {x}^{2} + 4](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%204)
So the inverse is
![{x}^{2} + 4](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%204)
The domain is [4, infinity)
The range is [0,infinity)
The domain of the inverse is [0, infinity)
The range is [4, infinity)
