Answer:
AB=(-0.5 , 0)
Step-by-step explanation:
Given point
A = (-3,-5)
B = (2,5)
AB = {(x1+x2)/2 , (y1+y2)/2}
AB = {(-3+2)/2 , (-5+5)/2}
AB = (-0.5 , 0)
Answer:
Not possible.
Step-by-step explanation:
250 = 2 * 5 * 5 * 5
From this you write the square root as 5 * √10 so you would have to use a calculator to get any further.
Answer (b): There is a strong positive correlation between time studied and test scores.
Reason:
(1) it is upward, so it is positive.
(2) They are closely packed, so there is a strong correlation.
Answer:
14x + x^2
------------------
9x^2
Step-by-step explanation:
2x /x^2 + (x-4)/ 9x
Cancel the common factor of x in the first term
2 /x + (x-4)/ 9x
We need a common denominator of 9x
2 /x *9/9 + (x-4)/ 9x
18/9x + (x-4)/9x
Add the numerators
18+x-4
--------------
9x
14+x
----------
9x
Multiply the top and bottom by x to get it to match one of the answers
14x + x^2
------------------
9x^2
