Answer:
The width is 8
Step-by-step explanation:
if the ratio of length to width is 9 to 4. and we know the length is 18, 18 is 2 times as much as 9, so 4*2=8.                   9*2=18,4*2=8

The standard form of a line:

We have the equation of a line in the slope-point form:
 use distributive property
      use distributive property
 add 3 to both sides
       add 3 to both sides
 multiply both sides by 2
        multiply both sides by 2
 subtract x from both sides
       subtract x from both sides
 change the signs
      change the signs

 
        
             
        
        
        
Answer:
Here's a possible example:
Step-by-step explanation:

Each piece is linear, so the pieces are continuous by themselves.
We need consider only the point at which the pieces meet (x = 3).

The left-hand limit does not equal ƒ(x), so there is a jump discontinuity at x =3.
