Walter is to make cookies for a basketball tournament. he's made 15 cookies so far. his coach asked him to make at least 20 cookies but no more than 55. solve the inequality and interpret the solution. 20 ≤ x + 15 ≤ 55 5 ≤ x ≤ 40; walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40; walter needs to make less than 5 more cookies or more than 40. 35 ≤ x ≤ 70; walter needs to make at least 35 more cookies but no more than 70. 35 ≥ x ≥ 70; walter needs to make less than 35 more cookies or more than 70.

First Option

Walter needs to make at least 5 more cookies but no more than 40

Step-by-step explanation:

If we call x the number of cookies that Walter needs to make, then we know that the amount of cookies will be:

Then this amount must be greater than or equal to 20 and must be less than or equal to 55 then.

and

This is:

We solve the inequality for x.

Then the amount of cookies that Walter must make must be greater than or equal to 5 and less than or equal to 40

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
