Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4
den301095 [7]

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

<u>Explanation</u>:-

Given equation is  –1 – 6 x = x – 15

<em>By addition property of equality </em>

<em>                        ⇒     - 1 - 6 x + 15 = x - 15 +15</em>

                      ⇒      - 6 x + 14  = x

subtracting 'x' on both sides ,we get

                       ⇒      - 6 x -x +14 =0

                        ⇒      - 7 x +14 =0

                         ⇒      -7 x = - 14

   Dividing '-7'  on both sides , we get

                                 x  = 2

<em>The solution of given equation is    x  = 2</em>

Is (5, 10), (-8, 3), (-1, 7), (-5, 10) A Function ?
ankoles [38]

Answer:

Step-by-step explanation:

Notice that the inputs {5, -8, -1, -5} are all different.  So we can immediately conclude that this is a function.

If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.
