You started with 40 baseball cards.
To find the answer to this problem, you need to work backward. 39(your current amount) - 19(the amount you added) = 20. And if 20 is only half of what you started with, you'd need to multiply 20 by 2, which is 40. So you started with 40.
Answer:
Jessica cut 3/8 of a yard
Step-by-step explanation:
9/10 x 5/12 =
45/120 =
3/8
Ok, so you got the parent function y = x^2 and it changed to y = x^2 -8
#'s inside the parenthesis would move it left or right and #'s outside the parenthesis would move it up or down. Since there are no parenthesis the x coordinate is 0, hence it doesn't move left or right. Because of this we know that the graph will be moved up or down. Now we look to see is the # negative or positive. If negative, we move it down. If positive, we move it up. Looking at this problem, we see that it will move it down. Next look at the #. This will indicate how <em>much</em> you will move the graph. In this problem, we will move the graph down 8.
Therefore,
When you change the graph y = x^2 to y = x^2 -8, you are moving the graph down 8.
$450,636.8878 is total amount(including initial amount) in 9 months.
$36,996.8878 is the amount of interest she earned(not including initial amount)<span />
No, it is equal to the decimal -.3333... 1/3^-1 however, would be equal to three since the negative exponent could be brought to the top and made positive, maybe that's what you were thinking of?
