This is a fraction. So it's y over x. So -12 over 9 equals y over -4. After you put those in fractions, you cross multiply. So -12(-4) is 48, and 9y. Then you set them equal to each other, so 48=9y. You divide 9 on both sides and your answer should be y=5.3
her mistake was that she was counting all the fourths as a whole sandwich when she really wraped up four sandwiches in total because 16 divided by 4 which is how many she cut it up into is 4 whole sandwiches
Answer:
If Discriminant,
Then it has Two Real Solutions.
Step-by-step explanation:
To Find:
If discriminant (b^2 -4ac>0) how many real solutions
Solution:
Consider a Quadratic Equation in General Form as

then,
is called as Discriminant.
So,
If Discriminant,
Then it has Two Real Solutions.
If Discriminant,
Then it has Two Imaginary Solutions.
If Discriminant,
Then it has Two Equal and Real Solutions.
5, 20, 80, 320, 1280, 5120, 20480, 81920, 327680, 1310720, 5242880, 20971520
The 12th term would be 20,971,520
Everything is being multiplied by 4 each time
