Answer:

x = -2, y = -2

Step-by-step explanation:

Your goal is to try and cancel out a variable. I want to get rid of y so i subtracted the first equation from the second one.

After that I solve for x and got x=-2.

I used x=-2 and plugged it back into either of the equation to solve for y.

Evaluate4-2x to the third power when x=3
iren [92.7K]
The answer to your problem would be -8

I got this because if you take 4 - 2x to the third power, it would look like this:
(4 - 2x)^3

All you have to do it plug in 3, solve for the equation in the parentheses, and then take that number to the third power. In this case, you get -2, and if you take that to the third power, you get -8.

Hope this helps!

when three different numbers are chosen from the set {-3,-2,-1,4,5) and multiplies the greatest possible product is
larisa86 [58]
1. We cannot pick both of the positive numbers 4 and 5 because the third one would be negative, and the overall product negative.

2. So we pick 5, the largest of (4, 5) and 2 negative numbers

3. Since the multiplication of the 2 negative numbers is positive, we pick the ones with larger absolute value, so -3 and -2

Answer: 5*(-3)*(-2)=5*6=30
