Any in my opinion I don't really know
Answer:
Last Graph (4th one)
Step-by-step explanation:
The equation given is
Since we want increase of 25%, the value of b would be 1.25, so we have:
The graph should be increasing so we can immediately eliminate 2nd and 3rd graphs since they are clearly decreasing. We now have to choose between 1st graph and 4th graph.
<u>1st graph:</u>
Let's take the point (-20,30)
<u>2nd graph:</u>
Let's take the point (-20,4.5)
hence, this makes sense. So the correct graph is 4th one.
Answer:
A
Step-by-step explanation:
Rational numbers are anything that can be expressed in the form a/b (that is, as a fraction aka a ratio). Pi is a value that goes on forever, so you can't set that up as a ratio; it's a famous irrational number. The square root of 34 is not even. If you put it in a calculator it gives you an ugly decimal, and if you try to convert it to a fraction, you can't. The same can be said for the square root of 40. The square root of 49, if you evaluate it, however, does give you a result you can work with: positive or negative 7. Both of these can be expressed as a ratio like 7/1 or -7/1.
Answer:
One tip I can give is to always line up your decimals when adding or subtracting.
Step-by-step explanation:
If you don't then you will get it wrong.
