A = 3 1/2 closest to friday
B = 3 closest to saturday
C = 6 1/2 just add 3 + 3 1/2 = 6 1/2
To find the inverse function, swap x x and y y , and solve the resulting equation for x x . If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables:
y=−x2−36 y = − x 2 − 36
becomes
x=−y2−36 x = − y 2 − 36 .
Now, solve the equation
x=−y2−36 x = − y 2 − 36 for y y .
y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36y=−x−36‾‾‾‾‾‾‾‾√ y = − − x − 36
ANSWER y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36 y=−−x−36‾‾‾‾‾‾‾‾√
3/10 + 2/6
use their lowest common multiple — which is 30 so:
3/10 -> 9/30 (multiply by 3)
2/6 -> 10/30 (multiply by 5)
then we can get the new equation of:
9/30 + 10/30 = 19/30
15(6 - g)
Simplify.
(15 × 6) + (15 × -g)
Simplify.
90 + (-15g)
Get rid of the parenthesis.
-15g + 90
