440 = 1 x 2 x 2 x 2 x 5 x 11
(1): 1 x 440
(2): 2 x 220
(2 x 2): 4 x 110
(5): 5 x 88
(2x2x2): 8 x 55
(2 x 5): 10 x 44
(11): 11 x 40
(2x2x5): 20 x 22
No need to continue because the next number is 2 x 11 = 22 and we already have that on the right side, so we have found all of the multiplicative pairs of 440.
Answer:
27
Step-by-step explanation:
9 crew members complete a job in 3 months
Number of crew members is inversely proportion to construction time :
Let :
Crew members = m
Construction time = t
m α 1 /t
m = k/t
m = 9 ; t = 3
9 = k /3
k = 27
If t = 1 (one month)
m =?
m = k/t
m = 27 / 1
Hence;
m = 27 * 1
m = 27 workers
Because it the -x is ^2 the shape of this line will be a parabola.
Hopefully this helps.
Answer:
x=-1
Step-by-step explanation:
5x+3=-2
subtract 3 from both sides
5x=-2-3
Subtract 3 from -2 to get -5
5x=-5
Divide by 5 on both sides
x=-5/5
Divide -5 by 5 to get -1
x=-1
Using the point on the graph (4, 1) solve for a
1 = a(4-3)² - 1
2 = a
