Answer:
(4,2/5) (−5,11/5)
Step-by-step explanation:
To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.
(7, - 2)
2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution
(- 5, - 4)
2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution
(4, )
2(4) + 10() = 8 + 4 = 12 → hence solution
(- 5, )
2(- 5) + 10( ) = - 10 + 22 = 12 → hence solution
Answer:
x
Step-by-step explanation:
Answer:
9+x = 2y+14
Step-by-step explanation:
It says 9 plus a number, so plug in x for 'a number', and it says 'is twice a number plus 14'. Plug in '=' for is another variable for 'a number', and last but not least, just put +14 for plus 14
