Which is the graph of g(x) = ⌈x + 3⌉?
koban [17]

Answer:

I can not tell what the graphs are but you would set up a table and plug it into the x value to calculate the y value

Step-by-step explanation:

____x_________y_______

3                  !

2                  !

1

0

-1

-2

-3

this is assuming that your brackets would be a straight lines which would be an absolute value  

if this is the case, then no matter what the answer for y is . . .Y would always be a positive number with the exception of the 3 or the negative three that would result in a 0 value

I hope this helps

A rectangle has a length of 5 yards and e width if 3 yards what is the perimeter explain your answer
Naddika [18.5K]
Since the question is asking for the perimeter, you have to find the length of the sides of the rectangle.

If one of the sides has a length of 5 yards, then the side parallel to that side also has a length of 5 yards.

So you have to multiply 5 with 2

5×2=10

If the other side has a length of 3 yards, then the side parallel to that side also a length of 3 yards

So you have to multiply 3 with 2

3×2=6

Then you add the two answers

10+6=16

So you get 16 yards


Hope this helps!
