Answer:
Graph has been shown in the attached file.
Step-by-step explanation:
We have been given the system of equations

Both the equation represents a straight lines. We can find the x and y intercepts of these lines to graph.
The intercept form of a line is given by

Here a is the x - intercept and b is the y-intercept.
Divide both sides of the equation (1) by 16

Hence, x-intercept = 4 and the point is (4,0)
y-intercept = 4 and the point is (0,4)
Similarly, for the second line
Divide both sides of the equation (2) by -6

x-intercept = -6 and the point is (-6,0)
y-intercept = -1 and the point is (0,-1)
We'll plot these points in the xy- plane and then join to get the graph of these lines.

Answer:
the original price of the cooker is £320 and David has been a deposit of 15% so find 15% of the original price and the deposit is £48
Answer:
Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank.
12/4=3
So if I added another 1/4 to the capacity:
It could hold 15 gallons.
All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.
15x2=30
30 bottles.
