Answer:

When (-1,-4) is substituted into the second equation, the equation  is true.

The ordered pair (-1,-4) is a solution to the system of linear  equations.

When (-1,-4) is substituted into the first equation, the equation is  true.

Step-by-step explanation:

Given

x - y = 3

7x - y = -3

Required

What is true about (x,y) = (-1,-4)

To do this, we substitute -1 for x and -4 for y in both equations;

For x - y = 3

-1 - (-4) = 3

-1 + 4 = 3

3 = 3

<em>Hence: </em>(-1,-4)<em> is true for </em>x - y = 3<em></em>

For 7x - y = -3

7(-1) - (-4) = -3

-7 +4 = -3

-3 = -3

<em>Hence: </em>(-1,-4)<em> is true for </em>7x - y = -3

3(2c-8) - 10c &gt; 0 can some one explain how to solve this ?​
Jet001 [13]

Answer:

c < - 6

Step-by-step explanation:

Given

3(2c - 8) - 10c > 0 ← distribute and simplify left side

6c - 24 - 10c > 0

- 4c - 24 > 0 ( add 24 to both sides )

- 4c > 24

Divide both sides by - 4, reversing the inequality symbol as a consequence of dividing by a negative quantity.

c < - 6
