Answer:
y = 5.5x - 17
Step-by-step explanation:
(4,5)(2,-6)
- M = ∆y/∆x
- -6-5/2-4
- -11/-2 this is the gradient
- chose any of the point then introduce another point
- (4,5) (x,y) the gradient is -11/-2
- M =∆y/∆x
- y-5/x-4 = -11/-2
- -2(y-5) = -11 ( x -4)
- -2Y + 10 = -11x + 44
- -2Y = -11x + 44 -10
- -2Y = -11x + 34
- divide the while equation by -2
- y = 5.5x + - 17
- y= 5.5x - 17
Well assuming that the riders get off so that others may get on it'll get pretty busy, just take the 3hrs. and convert them into min so that would be 180 min. then you divide the 180 min by 25 min. This will give you 7.2. You then multiply this 7.2 to the 35 people to get 252 people.
True. A relation just pairs two sets. An object in the first set can relate to more than one in the second.
Answer:
see below
Step-by-step explanation:
1st: x
2nd: 5x + 8
x(5x + 8) = 36
5x² + 8x = 36
5x² + 8x - 36 = 0
(x - 2)(5x + 18) = 0
(x - 2) = 0
x - 2 = 0
x = 2
1st: x = 2
2nd: 5x + 8 = 5(2) + 8 = 18
(5x + 18) = 0
5x + 18 = 0
5x = -18
x = -3.6
1st: x = -3.6
2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
Answer: Unit rate = 4/35 of a gallon per hour
=============================================
Work Shown:
3 & 1/2 = 3 + 1/2
3 & 1/2 = 6/2 + 1/2
3 & 1/2 = (6+1)/2
3 & 1/2 = 7/2
The faucet drips 2/5 of a gallon in 7/2 hours
2/5 gallon : 7/2 hours
2*(2/5 gallon) : 2*(7/2 hours) ..... multiply both sides by 2
4/5 gallon : 7 hours
(1/7)*(4/5 gallon) : (1/7)*(7 hours) ... multiply both sides by 1/7
4/35 gallon : 1 hour
The unit rate is 4/35 of a gallon per hour.
"Per hour" means "every 1 hour".
