Emeline can type at a constant rate of 1/4 pages/minute.
a. what is the ratio of the number of pages to the number of minutes?
b. emeline has to type a 5-page article but only has 18 minutes until she reaches the deadline. does emeline have enough time to type the article? why or why not?
c. emeline has to type a 7-page article. how much time will it take her?

a. 1/4

b. No, she does not have enough time

c. 28 minutes

Step-by-step explanation:

Emeline can type at a constant rate of 1/4 pages/minute.

a.the ratio of the number of pages to the number of minutes = 1/4 that she types 1 page every 4 minutes.

b. For a five page article she will take 5×4 minutes = 20 minutes( as she took 4 minutes for 1 page ). She won,t be able to complete task  before the dead line as she has got only 18 days.

c. Emeline has to type a 7-page article. so, she will take 7×4 minutes = 28 minutes to complete the task.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
