Answer:
Step-by-step explanation:
The answer is 34 because if you look closely at the number in the x column they are all decreasing by 4. So if you were to put the number 34 in the missing slot it would make the relationship proportional.
P = 2*(L + W) = 2*(51.125 +38.25)
P = 178.75 . . . ft . . . . . selection A

Step-by-step explanation:
5 1/6, 5 13/30, 5 68/90
Step-by-step explanation:
To find the equation you must first find the gradient and also look for the points on the graph.
I see point ( 0, 2) and point (4, 1)
Hence first find the gradient before equation
the gradient = y2-y1/x2-x1
y2 = 1
y1 = 2
x2 = 4
X1 =0
if you put in the values it will look like
1-2/4-0
-1/4
the gradient = -1/4
So for the equation the formula is
remember m is the gradient
y - y1 = m ( x - x1 )
so put in the value from only one point so you can choose either (0,2 ) or (4,1 )
I will go with (4, 1)
y - y1 = m ( x - x1 )
y - 1 = m ( x - 4 )
y -1 = -1/4 ( x - 4)
4 ( y-1) = -1(x-4)
4y- 4 = -1x +4
4y - 4 -4 = -1x
4y -8= -1x
4y + 1x -8 = 0
this is the equation.
thanks and good luck.
