A light bulb consumes 1800 watt-hours per day. How long does it take to consume 8100 watt-hours?

Answer:

y = 2x - 1

Step-by-step explanation:

4x - 2y = 2

So I'm assuming that your goal is to solve for the value of y in terms of x

First: the whole equation can be divided by 2

2x - y = 1

Second: subtract 2x from both sides

-y = -2x + 1

Third: divide each side by -1

y = 2x - 1

Done! I would appreciate Brainliest but no worries.

Answer:

So do you need to know the answer for x? know one knows what the question your asking is.

Step-by-step explanation:

Answer:

x=20 y=34

Step-by-step explanation:

x+14=2x-6

x=20

(20)+14=y

y=34

The x variable is for the number of books she buys to read so when x is 0!the cost would be what she paid for the reader.

The answer is B. The cost of the reader

Step-by-step explanation:

Median= n+1/2 ( if n is even )

So,

10+1/2=11/2=5.5

Therefore,

Answer:

chickens = 11

pigs = 7

Step-by-step explanation:

this would be solved using simultaneous equation

let c = chicken .

p = pigs

A normal pig and chicken both have 1 head. thus :

c + p = 18 equation 1

A normal pig has 4 legs and a normal chicken has 2 legs. Thus

2c + 4p = 50  equation 2

multiply equation 1 by 2

2c + 2p = 36 equation 3

subtract equation 3 from 2

2p = 14

p = 7

substitute for p in equation 1

c + 7 = 18

c = 11

I would say 12 and 14 because if you were to evaluate that square root, you would get −13.0384048104 and that would lie between 12 and 14.

If I'm wrong, sorry.

Answer:

y = 4x + 1

Step-by-step explanation:

Given the equation y = 4x - 2, we need to find the equation parallel to this line. Note that for two equations to be parallel to each other, the must have the same slope

Standard form of an equation is y = mx + b

Compare;

mx = 4x

m = 4

Since the slope of the given equation is 4, the required equation must also have a slope of 4

Since we are not given an option, we can assume any equation with a slope of 4

y = 4x + 1 will be parallel to the given equation since they both have the same slope

Note that the equation can be different so far they have the slope of 4

Answer:

(-1, 1)

Step-by-step explanation:

um i kinda feel like i got it wrong buuuuuuut yea

y=x²+2x+2

First, we should try to change the last number in a way so we can factor the entire thing

y=x² + 2 x + 1

tooo make it look like y=(x + 1 )²

the only difference between the original y=x² + 2x + 2

and the factor-able y=x² + 2x + 1 is simply changing the

2 to a 1 (Since we can't randomly change the 2 to a 1, we can add 1 and subtract a 1 to the equation at the same time to keep it balanced.)
