f(2) is x = 2

<u>Step 2: Solve</u>

  1. Substitute:                          f(2) = -2(2)² + 4(2) - 6
  2. Exponents:                         f(2) = -2(4) + 4(2) - 6
  3. Multiply:                              f(2) = -8 + 8 - 6

27. A 35 foot long tube is cut into two pieces with ratio 4:5 Find the length of the shorter piece.
polet [3.4K]

Answer:

x= 16 ft.

Step-by-step explanation:

Let 'x' and 'y' are the lengths of the two pieces then:

1.) x + y = 36

2.) x : y = 4 : 5 cross multiply

3.) 5x = 4y

by solving the system of equations

x + y = 36

5x = 4y

we find

x = 16 ft

y = 20 ft
