In the spring, you charge people $7 for going to their house to water flowers, then $4 for every hour you water. If you make $27 one day, how many hours did you spend watering?

5 hours

Step-by-step explanation:

If the total amount you made that day was $27 and there is a set cost of $7.00 you v=can subtract 7 from 27 then divide the remaining amount of money ($20) by the hourly wage ($4) and you get 5 hrs. Another way to look at it is 5 hrs times $4 or 5 times 4 = 20 +7 = $27

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
