1 and 4 will be the expression that makes the equatio. true for all values of x to prove i have done it in the picture attached in this message
Answer: it is a direct variation.
Justification:
In a direct variation the variables are related by a proportionality constant in this way:
y = k x
Tthan means that the value of y is always the product of a constant times the value of x.
The situation discribed for the coal may be written as:
number of tons of coal burned: c
number of hours: h
⇒ c = k × h
Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.
A. If there are only green and yellow M & M’s in the bag, what is the smallest number of
M & M’s possible? 7 M & M’s total
b. If there are 84 M & M’s in the bag all together, how many are green? 24 green ones
c. If red M & M’s were added to the bag in part b to get a total of 100, what is the ratio of green to yellow to red? 6: 15: 4
Answer: Because an equation is a simulation of a variety of numbers and due to the inevitability that all mathematical questions are designed to only have one answer,You can only get one solution
