Answer:
x>1
Step-by-step explanation:
20 < 5x +15
20 - 15 < 5x
5 < 5x
1< x
x>1
In order to validate Tom's claim, we have to calculate if indeed there is a common ratio with the consecutive y-values in the given ordered pairs.
1st and 2nd: r = 6/4 = 1.5
2nd and 3rd: r = 9/6 = 1.5
3rd and 4th: r = 13.5 /9 = 1.5
We have validated the existence of a common ratio. However this does not conclude that the function is quadratic because the ratio between the values is in first order.
Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:
Four less than p.
Is that correct?
Answer:
3 hundredths.
Step-by-step explanation:
After the decimal point the unit becomes tenths, hundredths, thousandths and so on. The 3 is in the hundredths column.
