Question

Can you put a number for I can know which question you answered?

Answer 1

1.) y=2

2.) y=4

3.) y=4

4.) y=-2

Explanation:

1.) y=2x Multiply 1*2. y=2

2.) do the same thing. 2*2. y=4.

3.) plug in the x value and do order of operations. y= 2(-4)-4. y=4.

4.) plug in your values again. y= -2(-3)-4. y= -2.

hope this helps!!

Answer 2

The first one is y= 2

The second is y=4

The third one is y=4

The last one is y=2

Explanation:

The easiest way to solve these types of problems is to Subsititute.

1) Givens: x=1; y=2x

Substitute

y=2

2) givens: x=2 y=2x

Substitute

y=4

3) Givens: x=-4; y=-2x-4

Substitute

y=4

4) givens: x=-3; y-2x-4

Substitute

y=2

Hope this helped :)
