Answer:
Step-by-step explanation:
common difference d=3-1=2
first term a=1
an=a+(n-1)d
2n-1=1+(l-1)2
2n-1=1+2l-2
2n-1=2l-1
l=n
(i used l for number of terms)
number of terms=n
Answer:
Step-by-step explanation:
The demand function is expressed as
D(p )=1150-50p
The supply function is expressed as S(p)=−200 + 40p
Where
p represents the price
A) The equilibrium price is the price at which the quantity supplied and the quantity demanded would be equal. Therefore
1150 - 50p = - 200 + 40p
40p + 50p = 1150 + 200
90p = 1350
p = 1350/90
p = 15
The equilibrium price is $15
b) For quantity demanded to be greater than quantity supplied, the price would be
1150 - 50p > - 200 + 40p
40p + 50p > 1150 + 200
90p > 1350
p > 1350/90
p > 15
The price would be greater than 15
c) if the quantity demanded is greater than the quantity supplied, the prices of the T shirt would increase.
Average speed: distance traveled/elapsed time
= 75/30
= 2.5 meters per second.

2,8 is the Awnser if you can see it on the graph it goes 2 up 8 right
Answer:
.
Step-by-step explanation:
3x - y = 17 .......A
10 × [x/5 + y/2] = 10 × 0
2x + 5y = 0 .......B
......A× 5 both 2 sides of equation
15x - 5y = 85 .....C
......B + ........C
2x + 15x = 0 + 85
17x = 85
x = 85/17
x = 5
put x value in ........A or .......B or ......C
you will receive y = -2
