14-3 (2x+1)=5-4x One solution was found : x = 3 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 2x (1-3x)-1+3x=0 Two solutions were found : x = 1/3 = 0.333 x = 1/2 = 0.500 Step by step solution : Step 1 :Equation at the end of step 1 : (2x β€’ (1 - 3x) - 1) + 3x = 0 This is how the solution of the equation 2 x 2 βˆ’ 12 x + 18 = 0 goes: 2 x 2 βˆ’ 12 x + 18 = 0 x 2 βˆ’ 6 x + 9 = 0 Divide by 2. ( x βˆ’ 3) 2 = 0 Factor. ↓ x βˆ’ 3 = 0 x = 3. All terms originally had a common factor of 2 , so we divided all sides by 2 β€”the zero side remained zeroβ€”which made the factorization easier.
Identify the piece that describes the function at x = 5 x = 5. In this case, x = 5 x = 5 falls within the interval 3 < x < 7 3 < x < 7, therefore use 3x 3 x to evaluate f (5) f ( 5). f (x) = ⎧ ⎨⎩3βˆ’5x x ≀ 3 3x 3 < x < 7 5x+1 x β‰₯ 7 f ( x) = { 3 - 5 x x ≀ 3 3 x 3 < x < 7 5 x + 1 x β‰₯ 7. The function is equal to 3x 3 x at x = 5 x = 5
