Answer:
<em>1) 6%</em>
<em>2) $1,689.35</em>
Step-by-step explanation:
1) Given the following
Sales tax = $64.80
Price of the computer = $1080
Required
rate of sales tax
Using the expression
x% of 1080 = 64.80
x/100 * 1080 = 64.80
10.80x = 64.80
x = 64.80/10.80
x = 6%
<em>Hence the rate of sales tax is 6%</em>
<em></em>
2) Given the following
Price of the car = $25,990
Tax rate = 6.5%
Sales tax charged = 6.5% of $25,990
Sales tax charged = 6.5/100 * 25,990
Sales tax charged = 6.5 * 259.9
Sales tax charged = $1,689.35
<em>hence the sales tax being charged is $1,689.35</em>
The graph is a function. When drawing a vertical line, there will be two circumstances:
- The line intersects only one point on a graph.
- The line intersects more than one point on a graph ( POI > 1 )
For the first circumstance, the graph that has only one intersect with a line - it is a function. For the second circumstance, the graph cannot be a function as it gives more than one y-value for a single x-value.
The conclusion is that if a line only has one intersect on a graph then it is a function. Otherwise, not a function but a relation instead. All functions are relations, but not all relations can be functions.
Answer
- The graph passes the vertical line test and is a function.
