You have to add 1 to  the -1 and you will get 0.What you have to do next is also add 1 to 15 because you want a variable on one side and a number on the other.So now you have 8k=16. So you divide 8 to 8k and you get nothing divide 8 and 16 and your answer for k =2 hope you get it right.trust mw it is very easy when you get use to it

In a theater, there are 4 long rows of chairs,each with an equal number of chairs There are 5 ahort rows of chairs,each with an
Hoochie [10]
<span>There are 4 long rows and 5 short rows in the theater. x represents the number of chairs in each long row and y represents the number of chairs in each short row.

So, total number of chairs in 4 long rows= 4x
Total number of chairs in 5 short rows = 5y
Total number of chairs in the theater on a normal day = 4x + 5y

When 2 chairs are added to each long row, the number of chairs will change to (x+2).
So, total number of chairs in 4 long rows will be = 4(x+2)

When 3 chairs are added to each short row, the number of chairs will change to (y+3)
So, total number of chairs in 5 short rows will be = 5(y+3)

Thus, total number of chairs in the theater in rush day = 4(x+2) + 5(y+3)
= 4x + 8 + 5y + 15
= 4x + 5y + 23

Thus we can say the number of chairs increase by 23 as compared to a normal day.

Through: (3, -5) and (0, -2) <br><br><br>please add the steps please.​
Vlad [161]
1: -5 = 3m + c
2: -2 = 0 + c

From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m

-5 = 3m - 2
m = -1

The equation of line is y = -x - 2

  • Starting point of arrow is -6.
  • The arrow is travelling to wards left.
  • I.e the arrow is decreasing and x is decreasing.

Hence the solution is

\\ \tt\hookrightarrow x\in (-\infty,-6]

  • x<=-6
