Consider the diagram.

planes m and n intersect at line d. lines a, b, and e are on plane m. line a is vertical and forms a right angle with line d. line b is diagonal and goes up and to the right. line e is at the top of the plane and is close to being horizontal. line c is on plane n and is goes slightly up and to the right.

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 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 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2
