Solve the system of equations by using subtraction. Y=2x+3 X-y=-2

Mathematics
1 answer:
Firlakuza [10]3 years ago
3 0

Answer:

y = 2x + 3 .... 1

x - y = -2 ...... 2

substitute the value of y in equation 2

x - (2x +3) = -2

x - 2x -3 = -2

-x = - 2 + 3

-x = 1

divide by -1 on both sides

x = -1

substitute the value of x in equation 1

y = 2 (-1) + 3

y = -2 + 3

y = 1

(x ; y)

(-1 ; 1)

Rachel has tossed a fair coin ten times. It landed heads up every time. Is this LIKELY?<br> Explain
serious [3.7K]

Answer: No

Step-by-step explanation:

Rachael getting a head every time she tosses a coin ten times is unlikely.

Theoretically, there will be some head and tails during the toss of the coin. Theoretically, there should be 5 heads after ten tosses of the coin.

To get exactly 10 heads during the tosses of coin, Rachel would need a larger trial to get a more accurate data.

Step-by-step explanation:

<em>The question is mixed up with another (See comment for correct question)</em>

Given

Length = 799in

Width = 245in

Required

The perimeter of the deck (this is what the question implies)

The perimeter (P) is:

P =  2 * (Length + Width)

P =  2 * (799 + 245)

P =  2 * 1044

P =  2088

Answer:

<h2>v=(13,-3)</h2>

solution,

- 2 =  \frac{x - 17}{2}  \:  \\  - 2 \times 2 = x - 17 \\  - 4 = x - 17 \\  - x =  - 17 + 4 \\  - x =  - 13 \\ x = 13 \\  \\ 7 =  \frac{y + 17}{2}  \\ 14 = y + 17 \\  - y = 17 - 14 \\  - y = 3 \\ y =  - 3

Therefore,

V=(13,-3)

Hope this helps...

Good luck on your assignment..
