Answer:
See example below.
Step-by-step explanation:
If the function has the table:
x f(x)
-3 -6
-2 -4
-1 -2
0 0
Step 1 : Looking at the table, find a pattern. This table f(x) deceases by 2 each time. This is a constant rate of change called slope.
Step 2: Recognize the pattern. Since it is decreasing by 2 each time, this is a linear function. Its equation can be written using y = mx+b.
Step 3: Use the form, y =mx + b and substitute m and b.
Step 4: The slope is m . The slope is -2. m = -2.
Step 5: Find the y-intercept. b is the y-intercept or starting point where x = 0. When x=0, the table shows y=0. So b=0.
This means the rule is y = -2x.
3y = 2x - 3
y = 2/3x - 1
the answer is C

It said my answer has to be 20 characters long but all you have to do is subtract so the answer would be 568
We know that there are 3,000 gallons in the swimming pool and that one hose filled it in x minutes (or hours, doesn't matter), while the second hose filled it 4x minutes. Together we have 5x (five parts that hoses have filled), so all we need to do is to divide 3,000 by 5:
3,000 ÷ 5 = 600
Now we can see that one hose filled <u>600 gallons</u>, while the other one filled 4 * 600 = 2,400 gallons.
