Answer:
25
Step-by-step explanation:
Well, if i rember correctly, all triangle have a total of 180 degrees, so 120 plus 35 = 155.
Then do 180 - 155 to get 25, which woud be your answer
Answer:
71
Step-by-step explanation:
Divide 71 by 7 and you get 10 and 1 leftover. Divide 71 by 4 and you get 17 with 3 leftover.
Hi there!
![\large\boxed{f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} } }](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bf%5E%7B-1%7D%28x%29%20%3D%20%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%2B4%7D%7B9%7D%20%7D%20%7D)
Find the inverse by replacing f(x) with y and swapping the x and y variables:
Isolate y by adding 4 to both sides:
Divide both sides by 9:
Take the cube root of both sides:
![y = \sqrt[3]{\frac{x+4}{9} }\\\\f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} }](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%2B4%7D%7B9%7D%20%7D%5C%5C%5C%5Cf%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%2B4%7D%7B9%7D%20%7D)
Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3
NO. They are not.
We can prove this by turning those numbers into fractions:
16 / 14 = 1.1428 ; 64 / 60 = 1.0667
Or simply:
64 / 16 = 4
60 / 14 = 4.29
To get the equivalent of 16 to 14; we must multiply both numbers by 4.
16 * 4 = 64
14 * 4 = 56
The equivalent of 16 to 14 is 64 to 56.
