Part A:
Yes this is a function of x. Specifically the function is f(x) = x^2
The inputs (x) are squared to get the outputs (y).
For example,
f(x) = x^2
f(-3) = (-3)^2 <<--- input is x = -3
f(-3) = 9 <<--- output is 9
The pair of values -3 and 9 are shown in the table (column on the very right side)
The fact that each input leads to exactly one output is what makes this a function. If we had an input lead to multiple outputs, then it wouldn't be a function.
=============================================================
Part B
Replace every x with 150 and then use the order of operations PEMDAS to simplify
f(x) = 20+3x
f(x) = 20+3*x
f(150) = 20+3*150 <<--- x has been replaced with 150
f(150) = 20+300
f(150) = 320
So the value of f(150) is 320
The input is 20
The output is 320
x is the number of hours
y or f(x) is the total cost
So this means f(150) = 320 represents the idea that 150 hours of renting the rowboat leads to a total cost of $320
The equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.
Given that Lexi packs 4 water bottles into each kit and total 120 water bottles are packed by Lexi.
We are required to find the equation which can be used to find the number of emergency kits that Lexi packs.
Equation is like a relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation and many more depending on the power of the variable that is present in that equation.
let the number of emergency kits that Lessi packs be x.
The equation which will shows the total number of bottles be:
=(Number of bottles in 1 kit)*x
Equation will be:
4x=120
Hence the equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.

Answer:
x=136.75
Step-by-step explanation:
Let's solve your equation step-by-step.
x+0.17x=160
Step 1: Simplify both sides of the equation.
x+0.17x=160
(x+0.17x)=160(Combine Like Terms)
1.17x=160
1.17x=160
Step 2: Divide both sides by 1.17
Answer:positive correlation
