0, 3
- 10, 15
= -10, -12
therefore, the slope is 6/5, and the intercept (c) is as supplied, 3.
the equation, y=mx+c or y = a + bx, can be applied here where m or b = 6/5, and a or c = 3.
therefore the equation is y=6/5x+3.
To test this, you can put in y = 10(6/5)+3, which spits out y = 15. This way we know it *should* work.
B.
For all 3 to work together, they can paint 1 room per hour.
C.
John can paint a room at 1/4 of a room per hour.
Rick can paint a room at 1/5 of a room per hour.
Together they can paint a room at a rate of 9/20 of rooms per hour.
D.
1 = 1/4j + 1/5r + 11/20m (john, rick, molli)
E.
The least common denominator is 20
F.
1 = 1/4(0) + 1/5(0) + 11/20x
1 = 0 + 0 + 11/20x
1 = 11/20x
x = 1/(11/20)
x = 1 9/11
It will take Molli 1 hour and 49 minutes (60 x 9/11) to paint the room alone.
The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
Answer:
1) p≥2
2) e-9=13
3) f<5
Step-by-step explanation:
1) If there are at least two slices left, there could be more, so use p≥2, meaning p is greater than or equal to 2.
2) e is your starting amount, so put that first, then it says it decreases by 9, so it is e-9=13.
3) If there are fewer than 5, it can not be 5 so you use <.
f<5 or gallons is less than 5.
