Patrick completes 13 questions every 52 minutes.
We're trying to find the time for Patrick to complete 1 packet.
Let's set these up as a fraction equation.
13/52 = 1/x, x being the variable that substitutes the time we're looking for.
13/52 can be simplified, though.
Divide both numbers by 13.
13 / 13 = 1
52 / 13 = 4
We now have:
1/4 = 1/x.
Well, this makes it easier. The numerators match, so the denominators must match as well.
x = 4.
It will take Patrick 4 minutes to complete 1 homework question.
I hope this helps!
Answer:
0
Step-by-step explanation:
![\text{If } g(x)=f^{-1}(x);$ and:$\\g(-15)=0,$ g(0)=3, g(3)=9, g(9)=20](https://tex.z-dn.net/?f=%5Ctext%7BIf%20%7D%20g%28x%29%3Df%5E%7B-1%7D%28x%29%3B%24%20and%3A%24%5C%5Cg%28-15%29%3D0%2C%24%20%20g%280%29%3D3%2C%20%20g%283%29%3D9%2C%20%20g%289%29%3D20)
We are to determine the value of ![f(f(9)).](https://tex.z-dn.net/?f=f%28f%289%29%29.)
Now:
![g(0)=f^{-1}(0)=3\\g(3)=f^{-1}(3)=9](https://tex.z-dn.net/?f=g%280%29%3Df%5E%7B-1%7D%280%29%3D3%5C%5Cg%283%29%3Df%5E%7B-1%7D%283%29%3D9)
From:
![g(3)=f^{-1}(3)=9\\f(9)=3](https://tex.z-dn.net/?f=g%283%29%3Df%5E%7B-1%7D%283%29%3D9%5C%5Cf%289%29%3D3)
From:
![g(0)=f^{-1}(0)=3\\f(3)=0](https://tex.z-dn.net/?f=g%280%29%3Df%5E%7B-1%7D%280%29%3D3%5C%5Cf%283%29%3D0)
Therefore:
![f(f(9))=f(3)=0](https://tex.z-dn.net/?f=f%28f%289%29%29%3Df%283%29%3D0)
Answer:
107
Step-by-step explanation:
the angle left of the 57 is 180-57 = 123
Sum of angles in quadilateral is 360, so
x = 360 - 60 - 70 - 123 = 107
Answer:
Step-by-step explanation:
If the ratio of the interior angle to the exterior angle for a regular polygon is 5:1, find:a. the size of each exterior angle, b. the number of sides of the polygon, c. the sum of the interior angles

Answer:
Slope-intercept form is y=mx+b (m = gradient, b = y-intercept)
So we want to make y the subject.
3x + 4y =-24
4y = -3x - 24
y = (-3/4)x - 6
