Rad15
use the pythagorean theorem on both triangles to find x
y^2 + 6^2 = 10^2
y=8
7^2 + x^2 = 8^2
x=radical 15
The x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.
Answer:
Inverse functions Inverse Functions If f is a one-to-one function with domain A and range B, we can de ne an inverse function f 1 (with domain B ) by the rule f 1(y) = x if and only if f(x) = y: This is a sound de nition of a function, precisely because each value of y in the domain of f 1 has exactly one x in A associated to it by the rule y = f(x).
Step-by-step explanation:
Hope it helps
B because of the y to the zero? Anyone wanna back me up?
