Answer:
Input variable x: Number of classes he attends.
Output variable y: Monthly cost
Slope: Cost per class, of $2
y-intercept: Membership fee, of $25.
Function: 
Step-by-step explanation:
This situation can be represented by a function is the following format:
In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).
We have that:
There is a membership fee of $25 per month and a fee of $2 per workout class he attends.
This means that 
. So
Answer:
The answer is 1/9.
Step-by-step explanation:
When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.
First take the number and flip the reciprocal, in this case -9 turns into -1/9.
Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9
Therefore the answer is 1/9.
Im pretty sure it would be product
Answer:you go to negative (0,-3) on the y axis then u go down by 3 and then over by 1 and keep doing that to form ur line
Step-by-step explanation:
Answer:
2839.4 meters
Step-by-step explanation:
Given that:
Altitude = 1200 m
Using trigonometry :
The distance from point P to the airplane :
Using trigonometric relation :
Sin θ = opposite / hypotenus
Sin θ = altitude / x
Sin θ = 1200 m / x
Sin 25 = 1200 / x
0.4226182 = 1200 / x
x = 1200 / 0.4226182
x = 2839.4423
Distance from P to airplane = 2839.4 meters
