Answer:
Yes, She is correct.
Step-by-step explanation:
Pythagorean theorem:
base² + altitude² = hypotenuse²
k² + k² = j²
Add the like terms. Like terms have same variable with same power.
2k² = j²
Answer:
1/x+2
Step-by-step explanation:
To find the inverse of the function, try switching the x value with the y value or function value
something like: x=1/g(x)-2
then, just manipulate the equation so that g(x) is by itself again, but this time, since it is an inverse, it's denoted as g-1(x)
x=1/g-1(x)-2
x+2=1/g-1(x)
(g-1(x))(x+2)=1
g-1(x)=1/(x+2)
