Leona [35]2 years ago

Answer:

\sf C)  \  x = -1\dfrac{2}{5}  , \  y =  \ 1\dfrac{3}{5}

Given equations:

  • a) -3x + 3y = 9
  • b) 2x - 7y = -14

<u>Make x the subject in equation 1</u>:

  • -3x + 3y = 9
  • -3x = 9 - 3y
  • x = y - 3

<u>Substitute this into equation 2</u>:

2(y - 3) - 7y = -14

2y - 7y = -14 + 6

-5y = -8

  y = -8/-5

  y = 1.6

Then x = y - 3

           = 1.6 - 3

           = -1.4

Solution: (x, y) ⇒ (-1.4, 1.6)

PLEASEEEE HELP AND DONT GUESS
Alja [10]

Answer:

Step-by-step explanation:

√12

Try putting it in your calculator. What digit comes next? Any number you pick from 0 to 9 is a guess. That's one of the ways you can tell if a number is irrational or not. You could get the answer from the calculator that came with windows. It gives the answer to 18 digits, but you'd still be guessing the 19th one.

The others are all well behaved in comparison.
