Answer:ok
Step-by-step explanation:
y = - 2x + 7; slope m = -2
Parallel lines, slope is the same
So y = -2x + b
b = y + 2x
Passing thru (4 , 1)
Plug in
b = 1 + 2(4)
b = 9
Equation
y = - 2x + 9
If B lies along the positive x-axis, then the coordinate of B is (12, 0). Since the right angle is at B and BC is 5, it means that C is 5 units above B.
Therefore, the coordinate of C is (12, 5)
the surface area of the collar is 12.3
