B. Lines 1 and 2 are parallel.

C. Lines 1 and 4 are parallel.

D. Lines 2 and 3 are parallel.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
