For the graph of the equation you wrote in Item 3, what does the y-intercept represent? A. Hours left to complete
B. Total hours of service
C. Hours completed each day
D. Days it takes to complete 30 hours

days it takes to finish the book

Step-by-step explanation:

y=450-39x

450= pages in book

-30= pages read each day

y= days it takes to finish the book

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
