Answer:
point slope form y+4 = -3(x+1)
slope intercept form y = -3x-7
Step-by-step explanation:
We have a point and a slope, we can use the point slope form for the equation
y-y1 = m(x-x1)
y--4 = -3 (x--1)
y+4 = -3(x+1)
We can also manipulate the equation into slope intercept form
Distribute
y+4 = -3x -3
Subtract 4 from each side
y+4-4 =-3x-3-4
y = -3x-7
Answer:= -12+4x
Step-by-step explanation:
Distribute -4 through the parentheses
8+4x=20
Calculate the difference
-12+4x
You cant really make a graph online but yiu have to know how many weeks she is saving for how much money she needs to save and once you find that out you multiply 8 by the number of weeks she is saving for. or take the number of how much money she needs to save and divide it by 8
Answer:
Identity property of multiplication.
Step-by-step explanation:
1.
He fills 5/6 lb per bag.
If he fills up 6 bags, he will use 6 * 5/6 lb = 5 lb.
Since he gets peanuts in 2-lb bags, he'd use 2 1/2 2-lb bags.
If he fills double that amount, 10 5/6-lb bags, he will use 10 lb of peanuts which is exactly 5 2-lb bags.
Answer: He should buy 5 2-lb bags.
2.
Each board has length x.
He cuts 3/5 of the length.
Each leftover piece is 2/5 of the length, or 2/5 x.
When he puts together several of the leftover pieces, he has 4 times the length of the original board, or 4x.
4x/(2/5 x) = 4x * 5/2 x = 10x
He has cut 10 boards.
