Step-by-step explanation:

Bobby sells 20 glasses of lemonade for $0.20 per cup.

Amount earned = $20\times0.20=4$ dollars

The average total cost is $0.17.

So, difference in selling amount and average = $0.20-0.17=0.03$ dollars

How do you solve: 81 X 9^(-2b-2)=27

Dominik [7]

Did you mean

81* 9∧(-2b-2)=27 => First divide whole equation with 81 and get

(3∧2)∧(-2b-2)=1/3 => 3∧(-4b-4)=3∧(-1) => -4b-4=-1 => -4b= -1+4 => -4b=3 =>

we will multiply whole equation with (-1) and get 4b=-3 => b=-(3/4)

If the start item is correct.

Good luck!!!

HELP HELP HELP HELP <br><br> What is the equation of the trend line in the scatter plot ?

Firlakuza [10]

Answer:

y = (4/7)x + 3

Step-by-step explanation:

rise = 7 - 3 = 4

run = 7 - 0 = 7

slope = rise/run = 4/7

y-intercept = 3

---------------------

Slope intercept form is

y = mx + b

m is the slope = 4/7

b is the y-intercept = 3

the equation is

y = (4/7)x + 3
