Answer:
D
Step-by-step explanation:
D cannot be solved using the quadratic formula since it lack a
Answer:
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
(-1, 0)(−1,0) is a x-intercept, because
For x=-1x=−1 the value of the function is equal to zero
(-6, 0)(−6,0) is a x-intercept, because
For x=-6x=−6 the value of the function is equal to zero
therefore
the answer is
the continuous function in the table has two x-intercepts
(-1, 0)(−1,0)
(-6, 0)(−6,0)
Answer:
, 
Step-by-step explanation:
Given
A motorboat takes 5 hours to travel 200 miles upstream and 4 hours to go downstream
Suppose the speed of motorboat in still water and rate of current be x and y respectively.
during upstream

During downstream

Add (i) and (ii) we get


Thus, the speed of boat in still water is
and rate of current is 
The answer has a mixed reaction is 1 1/2 but as an improper fraction is it 3/2!
