QUESTION 1 Karabo owns a gold coin shop where he buys and sells Kruger rand coins. He bought one ounce gold coin for R14 960 at 10-15 on a particular day and soit for R18 700 after 4.45 hours. 1.1 Write down the exact time of selling the gold coin. 1.1.2 Determine the profit the shop would make.​

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
