Can someone me out with my algebra one

y = (-1)*2^(x + 1)

Step-by-step explanation:

This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.

First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.

So there is an extra power somehow.

Try

y = 2^(x + 1) That looks promising

x = 1

y = 2^(1 + 1)

y = 2^2

y = 4

Try another one

x = 2

y = 2^(2 + 1)

y = 2^3

y = 8

I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.

What about that minus.

y = (-1)*2^(x + 1) should give a minus y value for any term.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
