Answer:
Not a function.
Does not pass vertical line test.
B.
Step-by-step explanation:
Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.
We say if it passes then it is a function.
It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.
If a single vertical line that you draw touches more than once, then it isn't a function.
When I say draw, I don't mean you should physically do it, but more so imagine it.
Now this particular relation is not a function because I can find a vertical line that touches more than once. Take the vertical line x=5 for example.
It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.
Answer:
<em>14850 inches</em>
Step-by-step explanation:
The complete question is...
A scale drawing of a living room is shown below:
A rectangle is shown. The length of the rectangle is labeled 5.5 inches. The width of the rectangle is labeled 3 inches. The scale is 1 to 30.
What is the area of the actual living room in square feet? Round your answer to the nearest whole number.
The ratio of the scale = 1:30
This means that the dimensions of the drawing has been reduced to 1/30 of the actual building's dimensions.
We first scale up the drawing to 30 times to get the dimensions of the actual building.
The length on the drawing = 5.5 inches
The real length of the actual building = 5.5 x 30 = 165 inches
The width of the drawing = 3 inches
The width of the actual building = 3 x 30 = 90 inches
The area of the actual building = length x width
==> 165 x 90 = <em>14850 inches</em>
Don't let fractions fool you.
of a tank in
an hour is equal to:
1/12 of a tank in 20 minutes.
Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).
3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.
Our answer is that it takes 4 hours to fill a tank.
Using the Quadratic formula
your answer would be A and C
X = 3
y = -3
You will see this using any graphing tool at your disposal.
