Answer:
The signup fee is $17
Step-by-step explanation:
we know that
The equation in point slope form is equal to

where 
m is the slope or unit rate of the linear equation
(x1,y1) is a ordered pair of the line
Let
x -----> the number of months
y -----> the total cost of a gym membership
In this problem we have
The slope of unit rate is equal to

The ordered pair is

substitute
 ----> equation in point slope form
 ----> equation in point slope form
Convert to slope intercept form
 
 
 
 
 ---> equation in slope intercept form
 ---> equation in slope intercept form
The y-intercept is the signup fee (value of y when the value of x is equal to zero)
therefore
The signup fee is $17
 
        
             
        
        
        
Answer:
a = -1 , b = 4 , c = 3 , d = 1
Step-by-step explanation:
The general rules of exponent:

===================================================
Given:

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z
Comparing the right hand side with the left hand side
∴ a = -1
∴ b = 4
∴ c = 3
∴ d = 1
