Answer: A. The slope is 
.
Step-by-step explanation:
The slope of a line helps to specify the direction of the line.
The slope of a line that passes through (a,b) and (c,d) is given by :-
Then the slope of a line passes through origin i.e. (0,0) and (-9,12) is given by :-
Hence, the slope is .
The measure of its complementary angle is 87 degrees. When two complimentary angles are added to each other they equal 90 degrees.
Answer:
f(-10) = 1,100
Step-by-step explanation:
f(-10) = (-10)^2 - (-10)^3
= 100 - (-1000)
= 1,100
