Answer:
A. 4
Step-by-step explanation:
1. Use the SLOPE FORMULA: M= rise/run= y2-y1/x2-x1
2. Plug in the two coordinates that were plotted on the equation: (1,1) & (3,9)
3. Label the coordinates
( 1 , 1 ) = ( x1, y1 )& ( 3, 9 ) = ( x2, y2 )
4. SOLVE & PLUG IN
m = 9 - 1 / 3 - 1 = 8 / 2
5. Simplify 8/2 (Divide by 2)
6. answer: 4/1 = 4
Answer:
C(x) = 
Step-by-step explanation:
Data provided in the question:
Area of the field = 3600 square feet
Fencing charges = $3.50 per foot
Let the side along the river be 'x' feet and the other side of the 'B'
now,
Area of rectangle = Bx = 3600 square feet
or
B =
feet
and total length to be fenced = x + 2B
therefore,
Total cost of fencing = Fencing charges × total length to be fenced
or
Total cost of fencing = $3.50 × ( x + 2B )
substituting the value of B from (1)
Total cost of fencing, C(x) = 
or
C(x) = 
1
