Answer:
-10,000 / -2000, although 10,000/2000 gives the same answer.
Step-by-step explanation:
The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.
Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.
Answer:
2) -1
Step-by-step explanation:
it is easy
we have to first open the brackets, as it is ' - ' we have to change the sign to opposite of that of the number in the bracket and then solve it.
so the number 2 is having negative sign, we make it positive. this rule is applied only when there is a negative sign and a bracket is there.
-3-(-2)
-3+2
=-1
Answer:
Step-by-step explanation:
1) The domain is related to the behaviour of the x
the graph started when x is -11 and finish when x is 1
so
D : [-11 ; 1]
or -11 ≤x ≤ 1
the range is related to the behavior of y
the graph start when y is -7 and finish when y = 0
Range : [-7;0]
or -7≤ y ≤ 0
You get a common denominator. It's 36. Then multiply accordingly to get 16/36-3/36 = 13/36. Hope this helps.
