Answer:
for every 3 packages, she uses 1/2 a roll of wrapping paper
if she uses 2 1/2 rolls.....
(2 1/2) / (1/2) ....* 3
(5/2) / (1/2).....* 3
(5/2 * 2) * 3
5 * 3 =
15 packages <===
Step-by-step explanation:
For y = -25, there is a slope of 0, as the line is a horizontal line situated at y = -25. Y = -25 is the correct y equation
Step-by-step explanation:
the answer is in the above image
Answer:
y = -3/2x + 13
Step-by-step explanation:
(6,4) and (2,10)
Slope:
m=(y2-y1)/(x2-x1)
m=(10-4)/(2-6)
m=6/(-4)
m = -3/2
Point-slope intercept:
y - y1 = m(x - x1)
y - 4 = -3/2(x - 6)
y - 4 = -3/2x + 9
y = -3/2x + 13
L = 2w + 3
The perimeter equation is:
2L + 2W = 78
Put what L equals in to find w:
2(2w + 3) + 2w = 78
6w + 6 = 78 ( I did a short cut)
6w = 72
6w/6 = 72/6
W = 12
At this point, put width back into the first equation to find the length
L = 2(12) + 3
L = 27
