since the difference of the first and third value is ten, each value is five more than the previous value
Answer:
4 weeks and 2 days
Step-by-step explanation:
There are 7 days in one week.
To convert 30 days into weeks and days, divide 30 by 7.
The biggest number you can divide it by is 4 [without going over 30]
7 x 4 = 28.
30 - 28 = 2.
So 30 days = 4 weeks and 2 days.

Answer:
Step-by-step explanation:
So to graph an inverse of the function given we have to switch the x and y values of the function:
So Ill do some points and the rest of the points the same process is applicable.
So our first point is (-1,1)
So our inverse point would be (1,-1)
The second point is (-2,2)
So our inverse point would be (2,-2)
The third point is (-3,3)
So our inverse point would be (3,-3)
Hope this helps!
Answer:
1. y=2x+15
2. 45.5 min
Step-by-step explanation:
1. You find 2x by looking at the give rate of gallons (2) a min (x). This information is given in the word problem. This gives the equation of y=2x. But you already have 15 gallons in the pool, so you need to add the +15 at the end of the equation giving you y=2x+15.
2. Y is the total gallons. This is 106 gallons (given in the word problem). We are trying to solve for x (# of minutes to fill the pool). 106=2x+15. subtract 15 from both sides giving 91=2x. Divide both sides by 2 giving x=45.5. It will take 45.5 minutes to fill up the pool.
