Question

If x=4 and y=-2, the value of 1/2xy^2 is

a. 32
b. 8
c. -4
d. -8​

Answer 1

I think the answer is 8 bc 0.5 x 4 is 2 and -2 x -2 is 4 and 4x2 is 8

Answer 2

b. 8

Explanation:

To solve, we need to plug in the x and y values since we already have the values given to us

1/2(4)(2^2)

We should do the exponents first, 2^2 is 4

Now we are left with 1/2(4)(4)

4 times 4 is 16

16 times 1/2 is the same as 16/2

16/2=8

b. 8
