Answer:
6.3 inches
Step-by-step explanation:
5/9 = 3.5/x
5x = 31.5
x = 6.3
9 chairs because 2 to 4 is equal to 1/2 and half of 18 chairs is 9
check attached file it has the answers
3x =-18
X= -12
Step-by-step explanation:
The coefficient of the x term repesents the slope of the graph.
So we have y = 2x +- ( ).
We have to find our number term, so let's substitute x = 4 and y = 3.
(3) = 2(4) +- ( )
3 = 8 +- ( )
To make this right, the number term must be -5.
3 = 8 - 5
So the equation is y = 2x - 5.
