Answer:
X=4
Step-by-step explanation:
Move the variable to the left side
13-4x+x=1
Subtract 13 on both sides
13-4x+x=1
-13 -13
Collect the like terms
-3x= -12
Divide both side4s by -3
-3x/-3= -12/-3
Answer:
X=4
Answer:
A) 25/75

Step-by-step explanation:
He started out with 75 planners, and has 25 planners left, meaning he have 25/75 (or 1/3) of the planners left.
25/75 = 1/3 = 0.333333(repeated decimal)

Answer:
+- square root of x+36
Step-by-step explanation:
f(x) = x^2 -36
y = x^2 -36
Exchange x and y
x = y^2 -36
Solve for y
Add 36 to each side
x+36 = y^2 -36+36
x+36 = y^2
Take the square root of each side
±sqrt(x+36) = y
±sqrt(x+36) = f^-1(x)
