Q:
For which of the following is x=-5 a solution. Select all that apply1. X+10=-52. -x^2+50=253. |2X|=104. X=O5. 2x<10
Accepted Solution
A:
Answer/step-by-step explanation:Number 1:x + 10 = -5x = -15No.Number 2:[tex]-x^{2} + 50 = 25[/tex] [tex]-x^{2} = -25[/tex] [tex]x^{2} = 25[/tex] [tex]x = -5,5[/tex] Yes.Number 3:[tex]|2x| = 10[/tex] [tex]2x = 10[/tex] [tex]x = 5[/tex] [tex]2x = -10[/tex] [tex]x = -5[/tex] Yes.Number 4:[tex]x < 0[/tex][tex]-5 < 0[/tex]Yes.Number 5:[tex]2x < 10[/tex] [tex]x < 5[/tex] [tex]-5 < 5[/tex] Yes.
