Answer:
n = -3
Step-by-step explanation:
The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.
I'm going to call the number "n."
n² - 24 = 5n subtract 5n from both sides to get the equation equal to zero
- 5n -5n
n² - 5n - 24 = 0 factor the trinomial into the multiplicatin of two binomials
we need factors (numbers that multiply) to -24 that add up to
-5. The only factors for -24 that will add up to -5 are -8 and 3.
(n-8)(n+3) = 0 set each binomial equal to zero and solve for n
n-8 = 0 or n+3 = 0
+8 +8 -3 -3
n = 8 or n = -3 n = -3 is the negative solution

Answer:
(-5,-6)
Step-by-step explanation:
Let(-3,-9)=(x1,y1)
(-7,-3)=(x2,y2)
Using midpoint formula,
Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)
=((-3+(-7))/2,(-9+(-3))/2))
=((-3-7)/2),(-9-3)/2))
=((-10/2),(-12/2))
=(-5,-6)
Thus midpoint(x,y)=(-5,-6)
