Answer:
The answer is 85
Step-by-step explanation:
The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).
n in this case is 10 (the number of numbers in the series)
an is 22 (plug in 10 to the expression 3n-8)
and a1 is -5 (plug in 1 to the expression 3n-8)
so when you plug everything in to the final equation, you get
(10/2) * (-5 + 22)
5 * 17
85
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
Set the equation equal to y
y = 2x+3
Exchange x and y
x = 2y+3
Solve for y
Subtract 3 from each side
x-3 = 2y+3-3
x-3 = 2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x -3/2 =y
The inverse is 1/2x -3/2
Divide 8/5 by 5/6 and you will get 1 and 23/25 is greater than v
So v is less than
1 23/25
