Tell how you know when you have found the prime factorization of a number
sweet-ann [11.9K]
When you end up with prime numbers for example
If you factored out 12 you could say 3x4. Now 3 is a prime number so it cant be broken down any more. You can break down 4 into 2x2. 2 is a prime number so cant be broken down any further. When 12 is factored out it is 2x2x3

The functions f (x) = 1/2x-3 and g(x) = -2x+ 2 intersect<br> at x = -2. True or false?
Norma-Jean [14]

9514 1404 393

Answer:

  False

Step-by-step explanation:

f(-2) = (1/2)(-2) -3 = -1 -3 = -4

g(-2) = -2(-2) +2 = 4 +2 = 6

The function values are not the same at x=-2, so the graphs do not intersect there.

__

The graphs intersect at x=2.

A bus and a train leave the same station at the same time and travel in the same direction along parallel routes. The train runs
MrMuchimi

Answer:

Smallest rate for the train is 50 mph and largest is 60 mph.

For the bus it is 25 and 30 mph.

Step-by-step explanation:

If the speed of the train is 2x then speed of the bus is x mph, and the train travels twice as far as the bus in a given time.

Distance = speed * time

For the largest rate:

d =  2x * 0.5   for the train

x = d

0.5d  =  x       for the bus

d - 0.5d = 15

0.5d = 15

d = 30

So the rate for the train =  30 / 0.5 = 60 mph.

In a similar fashion we can show that the smallest rate for the train is

25/ 0.5 = 50 mph.
