<h3>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>- inequality
- solving inequality
- PEMDAS
5 ≤ - 3x- 3 ≤ 10
<h3>to solve:</h3>x
<h3>let's solve:</h3>few notes about inequality
the direction of the inequality doesn't change if you
- Add (or subtract) a number from both sides
- Multiply (or divide) both sides by a positive number
- Simplify a side
the direction of the inequality does change
if you
- Multiply (or divide) both sides by a negative number
- Swapping left and right hand sides
Answer:
x =
Step-by-step explanation:
given, 50 - x^2 = 0
add x^2 to both sides, 50 = x^2
square root both sides, =
simplify, 50 / 5 = 10 / 5 = 2
you have a pair of 5's, and a 2, = x
