Answer:
x = - 2
Step-by-step explanation:
Givens
(2,5)
(x,3)
m = 1/2
Formula
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = 5
x2 = x
x1 = 2
1/2 = (3 - 5)/(x - 2) Cross multiply
1*(x - 2) = 2 (-2) Combine and remove the brackets.
x - 2 = - 4 Add 2 to both sides
x = - 4 + 2
x = - 2
Answer:
4n^3-n^2-5n
Step-by-step explanation:
n(2n+4n2−5−3n)
=(n)(2n+4n2+−5+−3n)
=(n)(2n)+(n)(4n2)+(n)(−5)+(n)(−3n)
=2n2+4n3−5n−3n2
=4n3−n2−5n
