Answer:
The answer to your question is:
first piece 44/3
second piece 35/3
third piece 5/3
Step-by-step explanation:
First we define the variable, it will be "x", and will be for the second piece.
Second piece = x
First piece = x + 3 (from the problem)
Third piece = x - 10 (from the problem)
We sum all
x + 3 + x + x -10 = 28
3x - 7 = 28 simplify like terms
3x = 28 + 7
3x = 35
Second piece x = 35/3
First piece = x + 3 = 35/3 +3 = (35 + 9)/3 = 44/3
Third piece = 35/3 - 10 = (35-10)/3 = 5/3
Step-by-step explanation:
x² - 5x - 24 = (x - 8)(x + 3).
When x² - 5x - 24 = 0, (x - 8)(x + 3) = 0.
By Zero product rule, x - 8 = 0 or x + 3 = 0.
=> x = 8 or x = -3.
Answer:
Replacing x with 3 in 4x-5 tells us f(3) = 7
Step-by-step explanation:
to evaluate f (3), just replace all x in f(x) = 4x - 5 with 3 :
f(3) =4(3) - 5 = 12 - 5= 7
