If you go on my profile you will see a similar problem that I already answered today.
Lets start by using a formula (don't remember the name)
(y-y1)=M(x-x1)
M is slope and y is first y value and y1 is second y value same applies to X.
Substitute in the values.
(5-q) = 10(-6-(-7))
5-q = 10*(1)
5-q = 10
-q = 5
q = -5
Check:
Substitute in the value of "q" and use the formula to find slope:
(y1-y)/(x1-x)
Substitute
(-5-5)/(-7-(-6))
-10/-1
10
Your Answer:
The value of "q" is -5
-4 has a solid dot, so -4 is included in the answer.
3 also has a solid dot, so 3 is also included in the answer.
All points between the two blue dots are also part of the solution.
Answer: Choice A.
Yes,
Every 2 minutes = 3 inches of water, so that means every minute = 1.5 inches of water.
So in 10 minutes:
10*(1.5) = 15 inches of water.
So in 10 minutes the tub will fill an additional 15 inches of water which is exactly how much you need to fill up the remaining tub (3+15 = 18)
7/21 math problems division = 0.333333333333.
0.333333333333 to 2 decimal places= 0.33
7/21 divided by 2 » (7/21) ÷ 2 » 0.333333333333 ÷ 2 = 0.166666666667 in long division
