Answer:
x = 704/39 ( <----Fraction)
Step-by-step explanation:
28 squared minus 39x minus 80 equals 0
784-39x-80=0 evaluate the power
704-39x=0 Subtract the numbers
-39x=-704 move the constant to the right hand side and change it's sign
Divide on both side to get x = 704/39
Answer:
![g^{-1}(x) = \sqrt[3]{\frac{x - 5}{4}}](https://tex.z-dn.net/?f=g%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%20-%205%7D%7B4%7D%7D)
Step-by-step explanation:
To find the inverse of a function, you can switch the "x" and "y" variables, then isolate "y", then change it back to function notation with the superscript ⁻¹.
You can't see "y" in the given function, but y = g(x). g(x) is the way you write "y" in function notation. The inverse function notation is g⁻¹(x).
Change "g(x)" to "y"
Switch the "x" and "y" variables
Subtract 5 from both sides to start isolating "y"
5 - 5 cancels out on right side
Divide both sides by 4
4y³/4 cancels out the 4 on the right side
Cube root both sides
∛y³ cancels out the ³ on the right side
Variable on left side is standard formatting
Change the inverse function notation g⁻¹(x)
The inverse of g(x) = 4x³ + 5 is g⁻¹(x) = ∛[(x-5)/4].
Given the equation I wouldn't think it would
The answer is B / the second option
K(x,y)>K’(-x,y-7)
Answer: D
Step-by-step explanation:
(5z + 15) - (11z + 2)
= (5z-11z) +(15-2)
= -6z+13
