Value of the expression for x = 3 1/3 is 29.
Step-by-step explanation:
- Step 1: Simplify the expression 3(2x+6)−(3x+1)
⇒ 3(2x+6)−(3x+1) = 6x + 18 - 3x + 1 = 3x + 19
- Step 2: Find the value of the expression for x=3 1/3
⇒ x = 3 1/3 = 10/3
⇒ 3x + 19 = 3 × 10/3 + 19 = 29
Subtract 16 to get
x^2 -25 = 0
Factor this as
(x -5)(x +5) = 0
The zero product property tells you the product will be zero when one of the factors is zero.
For x-5 = 0
x = 5
For x+5 = 0
x = -5
The appropriate choice is
3) x=-5 or x=5
Changing the slope from negative to positive
