Answer:
The coordinates of point X are (-11/2, 5/2)
Step-by-step explanation:
To find the coordinates of X , we shall apply the midpoint formula;
Mathematically, that would be;
(x , y) = (x1 + x2)/2 , (y1 + y2)/2
From the question
x1 = -3 , x2 = -8
y1 = 1 , y2 = 4
So substituting these values, we have;
(x ,y) = (-3-8)/2, (1 + 4)/2
(x ,y) = -11/2, 5/2
I got 36-2x, is x supposed to have a value?
Answer:
which of the following is the standard from of quadratic equation
Answer:Your left hand side evaluates to:
m+(−1)mn+(−1)m+(−1)mnp
and your right hand side evaluates to:
m+(−1)mn+(−1)m+np
After eliminating the common terms:
m+(−1)mn from both sides, we are left with showing:
(−1)m+(−1)mnp=(−1)m+np
If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:
(−1)(−1)mn=(−1)n.
It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:
(−1)(−1)mn=(−1)−n=1(−1)n
Multiplying both sides by (−1)n then yields:
1=(−1)2n=[(−1)n]2 which is always true, no matter what n is
Answer:
f=ab/a+b
Step-by-step explanation:
Let's solve for f.
1/f=1/a+1/b
