Answer:
Step-by-step explanation:
Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.
that is known as the vertical line test
Answer:
Both proportions are equivalent.
Step-by-step explanation:
We have been given two proportions
and
. We are asked to find why the solutions to our given proportions are equal.
We can solve proportions by cross multiplying them.
After cross multiplying our both proportions we will get same equation that is:
![40*10=8*x](https://tex.z-dn.net/?f=40%2A10%3D8%2Ax)
![400=8x](https://tex.z-dn.net/?f=400%3D8x)
![8*x=40*10](https://tex.z-dn.net/?f=8%2Ax%3D40%2A10)
![8x=400](https://tex.z-dn.net/?f=8x%3D400)
Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.
Answer:
20
Step-by-step explanation: easy j is 16 years old and m is 4 years older so m is 20
55-30=25
So it is + 25 dimes
