How many solutions are there to the following system of equations?. . 2x – y = 2. –x + 5y = 3. A. 1 B. 0 C. 2 D. infinitely many

krek1111 [17]

2 x - y = 2
- x + 5 y = 3 / *2
----------------------
2 x - y = 2
+
- 2 x + 10 y = 6
-----------------------
9 y = 8, y = 8/9
2 x - 8/9 = 2
2 x = 2 + 8 /9
2 x = 26/9
x = 13/9
( x, y ) = ( 13/9, 8/9 )
Answer: A ) 1 solution.

1. m+ 10< 16

sleet_krkn [62]

Answer:

$1.\ m$

Step-by-step explanation:

1. Subtract 10 from both sides. Then:

$m+ 10< 16\\ m+ 10-10< 16-10\\m$

2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:

$-2g\geq8\\\\\frac{-2g}{-2}\geq\frac{8}{-2}\\\\g\leq-4$

3. Add 22 to both sides. Then:

$y-22< 19\\ y-22+22$

4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:

$-7b>-28\\\\\frac{-7b}{-7}>\frac{-28}{-7}\\\\b$

5. Subtract 30 from both sides. Then:

$h+30$

6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:

$-5x$

7. Subtract 13 from both sides. Then:

$t+13>22\\ t+13-13>22-13\\t>9$

8. Add 12 to both sides. Then:

$w-12< 16\\ w-12+12$
