see below
Step-by-step explanation:
Equilibrium quantity means the quantity supplied at a given price is equal to the quantity demanded at that price. To find it, look for the line in the table where quantities are equal. That line tells you the equilibrium price as well as quantity.
_____
On a graph, it is the point where supply and demand curves intersect (quantities are the same at the corresponding price).
Answer:
n = 3
Step-by-step explanation:
start by combining 'like' terms on each side of equation to get:
7n - 9 = -3n + 21
add 3n to each side to get:
10n - 9 = 21
add 9 to each side to get:
10n = 30
n = 30/10 or n = 3
Check:
7(3) - 9 = -3(3) + 21
21 - 9 = -9 + 21
12 = 12
One number is x
second number is x+1
x²+(x+1)²=85
x²+x²+2x+1=85
2x²+2x-84=0
x²+x-42=0
(x+7)(x-6)=0
x=-7, x=6
we need positive number, so we take 6
x=6
x+1=7
