Find the value of the expression 2x^2y if x=-1 and y=3

12

Step-by-step explanation:

This value would be 2(-1)^2*2(3).  I have enclosed the given values of x and y for clarity.

This works out to 2(1)*2(3) = 12.

i would say c is the best answer, hope it's right!

good luck! =)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
