Answer:
a) (x/7)^1/9=y
Step-by-step explanation:
f(x) = 7x^9
x/7= 7y^9/7
(x/7)^1/9=(y^9)^1/9
(x/7)^1/9=y
f^-1(x) is a fuction because it passes the vl test
Answer:
x = -6
Step-by-step explanation:
-5x+1=31
- Subtract 1 from both sides of the equation.
-5x = 30
x = -6
Answer:
Step-by-step explanation:
Let angle ABZ be angle 1 and angle ZBC be angle 2.
Angle 1 = 85 degree
Angle 2 = 6x + 9
measure of angle ABC = 24x+4
Angle 2 = ABC - 85
6x + 9 = 24x + 4 - 85
6x - 24x = 4 - 85 - 9
-18x = -90
x = -90/-18 = 90/18 =
x = 5
Therefore the measure of angle 2 = 6*5 + 9 = 30+9 = 39 degree
Therefore the measure of angle ZBC = 39 degree

Answer:
Let x = the width of the smaller rectangle.
The length of the smaller rectangle is 2x - 1.
Area is A = lw
So the area of the smaller rectangle is A = (x)(2x - 1) = 2x^2 - x
