An airplane's altitude in feet during its descent can be found using the equation y=-200x + 20,000. After new government
regulations become law the descent is now modeled by the
equation y= -200x + 20,500. Which statement describes this
change?
a) The airplane starts its descent from an altitude 500 feet
higher
b) The airplane starts its descent from an altitude 500 feet
lower
c) The airplane descends 500 feet per horizontal mile faster.
d) The airplane descends 500 feet per horizontal mile slower.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

step-by-step explanation:

the true ones are a b and d

answer: 0.1,0.85

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
