Answer 1

Step-by-step explanation:

Explanation:

First, simplify the equation so the absolute value is all that remains on the left side of the equation:

|2x – 25| = 10

Now create two equalities, one for 10 and one for –10.

2x – 25 = 10 and 2x – 25 = –10

2x = 35 and 2x = 15

x = 17.5 and x = 7.5

The two solutions are 7.5 and 17.5. 17.5 + 7.5 = 2

hope it helps uh ☺❤

Answer 2

Given inequality:

$\sf{\sqrt{6+x} ≥ 6-x}$

Squaring on both sides:

6 + x ≥ (6 - x)²

» 6 + x ≥ 36 + x² - 12x

» x² - 13x + 30 ≤ 0

» x² - 3x - 10x + 30 ≤ 0

» x(x - 3) - 10(x - 3) ≤ 0

» (x - 10)(x - 3) ≤ 0

Critical Points: 3, 10

By wavy curve method:

$\sf{ x \in [3,10] }$

Thus, Option D. None Of These ✓
