Hello from MrBillDoesMath!

Discussion:

Area of a circle of radius "r" is given by the formula

just olya [345]

Answer: 15 1/3 months

Step-by-step explanation:

Daniella has $210 in the bank, and her balance grows at a rate of $3 each month. This can be written as:

b = 3m + 210 ...... equation i

Lori has $187 in the bank and her balance grows at a rate of $4.50 each month. This can be written as:

b = 4.5m + 187 ....... equation ii

Combine both equations

b = 3m + 210

b = 4.5m + 187

3m + 210 = 4.5m + 187

4.5m - 3m = 210 - 187

1.5m = 23

m = 23/1.5

m = 15 1/3 months

in a round robin tennis tournament involving 7 players, each player will play every other player twice. How many total matches w
baherus [9]
Total number of ways to make a pair:

The first player can be any one of 7 .  For each of those . . .
The opponent can be any one of the remaining 6 .

Total ways to make a pair  =  7 x 6 = 42 ways .

BUT ... every pair can be made in two ways ...  A vs B  or  B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.

If every pair plays 2 matches, then  (21 x 2) = <em><u>42 total matches</u></em> will be played.


Now, is that an elegant solution or what !

Verify if f and g are inverse functions.
Andrej [43]
They are not, because inverse means multiply by -1, therefore, there should be a positive sign in front of 2 and a negative in front of x for G(x) = x - 2
