So, Using your conversion chart(if you have one) you'd see 1 liter makes 1000 milliliters. So, if you have half of a liter(0.5), then you have 500 milliliters. If he adds 300 more, then you get 800 milliliters total, which is also equal to 0.8 liters. Hope this helps!
Step-by-step explanation:

If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.
Your answer is A.
Answer:

Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5

Subtract x from both sides


Divide both sides by 3


The slope of the line is the coefficient of x
Slope = 
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of 
Having calculated the slope, next is to calculate the equation of the line using the following formula;

Where m is the slope; m =
; 
Substitute these values in the formula above; the formula becomes


Cross Multiply

Open brackets

Add x to both sides


Add 6 to both sides


Multipby both sides by -3




Comparing the above to Ax + By = 3
