Mateo has already swum Four-fifths of the 2,000 meters he is swimming today. If he continues swimming at a pace of Three-fourths of a meter per second, which expression shows the amount of time it will take him to swim the remaining distance? A. 2000 times four-fifths times three-fourths B. 2000 times four-fifths divided by three-fourths C. 2000 times one-fifth times three-fourths D. 2000 times one-fifth divided by three-fourths

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

1/4 is the asnwer cuz 5/20 is the faction
