Problem would be easier to do if you'd write one function above the other:
<span>3x-2y=3; 6x-4y=1 should be:
</span><span>3x-2y=3
</span><span>6x-4y=1
------------
Please note that if you mult. the first equation by 2, you get 6x-4y= 6, which is almost but not quite the same as the second equation.
It should be obvious that 6x-4 in the first equation are the same expression as 6x-4 in the second equation. 6x-4 cannot = 6 and also =1 at the same time, so this system has NO solution. The 2 lines never intersect.

An expression which is represented by the diagram (see attachment) is: A. -6 - (-1).
<h3>What is an expression?</h3>
An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
By critically observing the diagram (see attachment), we can logically deduce the following information:
- There are a total of 6 negative tiles.
- Among the 6 negative tiles, 1 tile is crossed out.
In this context, we can the diagram (see attachment) by using the following expression:
-6 - (-1)

The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.
