Jonathan found that the correct equation -2|8-x|-6=-12 had two possible solutions: x=5 and x=-11. which explains whether his solutions are correct?
a) he is correct because both solutions satisfy the equation.
b) he is not correct because he made a sign error.
c) he is not correct because there are no solutions.
d) he is not correct because there is only one solution: x=5

D

Step-by-step explanation:

Check the solutions by substituting the values of x into the left side of the equation and if equal to the right side then they are a solution.

x = 5

- 2 | 8 - 5 | - 6 = - 2 | 3 | - 6 = (- 2 × 3) - 6 = - 6 - 6 = - 12 ← correct

x = - 11

- 2 | 8 + 11 | - 6 = - 2 | 19 | - 6 = (- 2 × 19) - 6 = - 38 - 6 = - 44 ≠ - 12

Thus x = 5 is a solution but x = - 11 is not → D

The solutions to the equation are in fact x = 5 and x = 11

Step-by-step explanation:

if you want to find the solutions here is a method:

-2|8-x|-6=-12

divid by -2 :

|8-x|+3=6

|8-x| = 3

8-x = 3 or 8-x=-3

x= 5 or x=11

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
