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

The first one is y= 2

The second is y=4

The third one is y=4

The last one is y=2

Step-by-step 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 :)

1.) y=2

2.) y=4

3.) y=4

4.) y=-2

Step-by-step 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!!

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
