Answer:
9:72
Step-by-step explanation:
Let's use apples and oranges to define the ratio. A ratio of 1:8 would mean for every 1 apple there are 8 oranges. If we have 9 apples then we would have 9*8 oranges.
So...
1:8
9:72
Do you mean scientific notation?
If so,
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
In order to write a number in scientific notation, I suggest you place the tip of your pencil right after the last digit in the number.
Then go backwards, counting each jump to the next number (this will be your exponent number).
You will go backwards until you reach your first NON-ZERO digit, which is where you will place the decimal point.
Multiply the decimal you now have by 10 (multiplying by 10 applies every time!) and then to the power of however many spaces you went back.
Answer:
x-int = (1,0)
y-int = (0,4)
Step-by-step explanation:
For the x-intercept, you see that there is a dot indicating that x = 1. So, since the dot is on the line, the y-axis is 0, (1,0).
Then for the y-intercept, you see that there is a dot on the y-axis which means y = 4. So, since the dot is on the line, the x-axis is 0 instead of the y-axis, (0,4).
Hope this helped you and you get it right. I really care about your understanding of it ^^
