First you do parenthesis, then you add and divide to get those variables by themselves, soon you will have the answer to your problem Hope this helped :) and I hope it wasn't a fishy answer>)))'>:(
Answer:
4
Step-by-step explanation:
She can use a dime and a quarter to buy one package. With 3 dimes and more than 3 quarters, she can buy 3 packages this way.
She can use 2 nickels and a quarter to buy one package. With 2 nickels and the 2 remaining quarters, she can buy 1 package this way.
Mae-Ying can buy 4 packages, and will have 1 quarter left over.
_____
You can add up her money and divide by 35¢ to find the number of packages. Doing that, you get ...
5·0.25 +3·0.10 +2·0.05 = 1.25 +0.30 +0.10 = 1.65
Then 1.65/0.35 ≈ 4.71, so Mae-Ying can buy 4 packages with the money she has.
1) We can determine by the table of values whether a function is a quadratic one by considering this example:
x | y 1st difference 2nd difference
0 0 3 -0 = 3 7-3 = 4
1 3 10 -3 = 7 11 -7 = 4
2 10 21 -10 =11 15 -11 = 4
3 21 36-21 = 15 19-5 = 4
4 36 55-36= 19
5 55
2) Let's subtract the values of y this way:
3 -0 = 3
10 -3 = 7
21 -10 = 11
36 -21 = 15
55 -36 = 19
Now let's subtract the differences we've just found:
7 -3 = 4
11-7 = 4
15-11 = 4
19-15 = 4
So, if the "second difference" is constant (same result) then it means we have a quadratic function just by analyzing the table.
3) Hence, we can determine if this is a quadratic relation calculating the second difference of the y-values if the second difference yields the same value. The graph must be a parabola and the highest coefficient must be 2
