She should bring $320. 120+45+65+30x2+30=320. 120 is on hotels. 45 is about gas for the car. 65 is on food. The ticket price a day is $30, and if Rachel is going twice, then it is 30x2, or 30+30.
Answer:
-12
Step-by-step explanation:
Since we want to find g(9), we will use the function g(x):
Substitute:
Multiply:
Add:
So, our answer is -12 :)
<span>3x+4=y+5, then y+5=3x+4
It is called: reflexive property

<span>x = y and y = 10, then x = 10
It is called: equality substitution property

Answer: Yes, y does vary directly with x.
Constant of variation = 1/4
The function rule is y = (1/4)x
=========================================================
Explanation:
Let's assume that y does vary directly with x.
If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.
Solving for k gets us k = y/x
For each row, divide the y value over the x value
- row one: k = y/x = 14/56 = 0.25
- row two: k = y/x = 20/80 = 0.25
- row three: k = y/x = 22/88 = 0.25
Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.
So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x
For the Unit Test the answer is A.
