Question

X3 + 5y when x = 4, y = -3

Answer 1

Answer:

49

Step-by-step explanation:

First, because of the order of operations, you would do 4^3 (or four to the power of three) first to get 64. 5×-3 is equal to -15, and a positive number plus a negative number is just that positive number minus a positive version of the negative number, if that even makes sense. Basically, 35 + -2 would be equal to 35-2. 64-15 is equal to 49, which is your answer!

I hope this helped you!

Answer 2

Answer:

49

Step-by-step explanation:

4^3=64

64+(-15)=49
