Pounds will be represented by x and the cost will be represented by y. The equation is Y=3x. For the graph just use substition for x and then calculate the outcome and graph it.
So you need to find the $ for one hour of work
if 16=135
1 hour= $8.50
$8.50*24= $204
answer=$204
hope this helps :)
Answer: The triangles are reflected across the line y = x
Step-by-step explanation:
I used wolfram to calculate it for me. I used the bottom right point of the triangle.
Well it simplifies to -23x-3 so i would say 4 is ur answer
'y' is NOT the number of chairs in each row and column. It's the TOTAL number of
chairs, so it's the product of (chairs in each row) times (chairs in each column).
The problem says that those numbers are equal. So we would expect the TOTAL
to be a perfect square, and the number in each row and each column to be the
square root of the total. Since the total is 81, the number in each row and column
could be either +9 or -9 . Both answers are mathematically correct, but -9
doesn't make sense in the real world. So we know that +9 is the real answer.
