Olivia bought a $1,874 sprinkler system with her credit card. Her credit card has an APR of 10. 31%, compounded monthly. She made no other purchases on the card until the sprinkler system was fully paid for, which took four years of identical monthly payments. Over the eight years that Olivia kept the sprinkler system, it used an average of $2. 11 in water per week. After eight years, what percentage of the total lifetime cost of the system did the original price make up? (Round all dollar values to the nearest cent. ) a. 81. 66% b. 59. 07% c. 38. 25% d. 72. 33%.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

answer: 414,377,008

step-by-step explanation:

just multiply it

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
