Answer:
110
Step-by-step explanation:
To find the constant of variation, divide the number of km by the number of hours:
165/1.5
= 110
This means that the speed of the train is 110 km per hour.
So, the constant of variation is 110.
Answer:
285,000
Step-by-step explanation:
First, you need to figure out how much was profit. Multiply 300k by .05, which should give you 15,000. Then, subtract 15,000 from 300k to get 285k. hope this helps

Multiply the first coefficient (3) and the last term (2) to get 3*2 = 6
We need to find two numbers that
a) multiply to 6
AND
b) add to -5 (middle coefficient)
Such two numbers are -3 and -2
-3 times -2 = 6
-3 plus -2 = -5
So we can break up the -5x into -3x-2x and then factor by grouping
--------------
3x^2-5x+2
3x^2-3x-2x+2
(3x^2-3x)+(-2x+2)
3x(x-1)+(-2x+2)
3x(x-1)-2(x-1)
(3x-2)(x-1)
So the two factors are (3x-2) and (x-1)
The answers are A and C
