Notice how points T and Z are vertically aligned, or vertically lined up. This is where the graph fails the vertical line test.
The input x = 2 leads to the outputs y = 3 and y = 5 (which are the y coordinates of points Z and T in that order).
A function is only possible when any given input leads to <u>exactly one</u> output only. It would be like saying "the conversion function from Celsius to Fahrenheit has 0 degrees C convert to both 32 degrees F and 50 degrees F at the same time". But such a statement makes no sense and it's not useful. So this is one example of why having one output makes sense for a function.
In short, we need one output for any given input. But the input x = 2 leads to more than one output. That's why we don't have a function.
Answer: Half of a apple pie
Step-by-step explanation:
1/2 is half
Answer: 4:20 but that simplified would be 1:5
Triangles to squares
Answer:
18 minutes
Step-by-step explanation:
5 mins = 10 pages
10 mins = 20 pages
15 mins = 30 pages
20 mins = 40 pages
Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.
2 is the amount of pages you read in 1 minute.
so 1 minute = 2 pages
Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.
then you start adding 1 minute until you get to 36 pages.
15 minutes = 30 pages
16 minutes = 32 pages
17 minutes = 34 pages
18 minutes = 36 pages
Therefore, it should take 18 minutes to read all 36 pages.
(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)
Percent problems can be solved by writing equations. An equation uses an equal sign (= ) to show that two mathematical expressions have the same value. Percents are fractions, and just like fractions, when finding a percent (or fraction, or portion) of another amount, you multiply. ... Percent of the Base is the Amount.
