Answer:
C) x/2 +2y = 4
Step-by-step explanation:
Of the equations offered, only equation C has the given point as a possible solution.
___
Since the graph is not given, we don't know if the given point is on the graphed equation.
Somewhere in the text, it must say that x = 2 and y = -1 or else, the values just seem made up out of thin air.
Answer:
15.3 dollars
Step-by-step explanation:
13.50 + (.09 x 20 = 1.8)
13.50 + 1.8
Let width of the floor be x feet, them area is
x(x+2) = 168
x^2 + 2x - 168 = 0
(x - 12)(x + 14) - 0
so x = 12
the floor is 12 ft by 10 ft
the width of the rug should be 10 - 2(2) = 6 feet
