Answer:
(a) x - y + 1 = 0
Step-by-step explanation:
One way to address multiple-choice questions is to try the answers to see what works.
For the lower left point (1, 2), the answer choices shown give ...
x -y +1 = 1 -2 +1 = 0 . . . . . equation works
-x -y +1 = -1 -2 +1 = -2 . . . doesn't work
y -x +1 = 2 -1 +1 = 2 . . . . . doesn't work
The appropriate choice is ...
x - y + 1 = 0

Answer:
The width is: 
The length is 
Step-by-step explanation:
The given rectangle has area given algebraically by the function:

The width of the rectangle is the greatest common factor of
,
and 
That is the width is: 
We now divide the area by the width to obtain the length of the rectangle:

This simplifies to:


The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function , which is

When the grasshopper land on the ground,

that is,

Multiplying whole equation by 12 to get rid of denominators 3 and 4


And time cant be negative, so the correct option is

Correct option is C .
A 3x + 2
Step-by-step explanation:
3x+2 is a polynomial.
If the variable in a term of polynomial is multiplied by a number, then this number is called the "coefficient"
It contains a first degree term as highest degree term and one constant term.
coefficient=3
constant=2
variable=x(first degree term)
