f(x) = -x + 2
f(-1) This means that they want you to find the value of f(x) or y when x = -1.
f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1
f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)
f(-1) = 1 + 2
f(-1) = 3

Here's your answer to the first problem
Answer:
V = a³/8
Step-by-step explanation:
The volume of the original cube is the cube of the side length:
V = a³
When the side length is reduced to half its former value, the new volume is ...
V = (a/2)³ = a³/2³
V = a³/8 . . . . volume of the new cube
Answer: 119
Step-by-step explanation:
Let the acre of wheat to be cultivated be x.
Since the farm must grow three times as many acres of corn as wheat, therefore, corn = 3x
The information given can be used to form a equation as:
42(3x) + 30x = 18564
126x + 30x = 18564
156x = 18564
x = 18564/156
x = 119 acres of wheat
