Answer:
-2y^2 + y +32
Step-by-step explanation:
The variable with the highest exponent is y^2
1) 10.25 x 10^9 in scientific notation is 1.025 x 10^10
2) Now you have to subtract 10.25x10^9 - 3.0x10^7
To make that you have to put both numbers with the same power of ten.
1025x10^7 - 3.0x10^7 = 1022x10^7 more pennies than half-dollars.
This is your answer x=4, y=2
