For this item, complete the choice matrix by clicking the appropriate answer in each row. A customer buys an item that originally costs x dollars from a retail store and uses a $10.00 off coupon. The store clerk uses the function C(x)=1.06(x−10) to calculate the final cost of the customer’s item.

Determine whether each statement about C(30) is true or false.

True

False

The value of C(30) is 20.

True – The value of C ( 30 ) is 20 .

False – The value of C ( 30 ) is 20 .

The value of C(30) is 21.2.

True – The value of C ( 30 ) is 21.2 .

False – The value of C ( 30 ) is 21.2 .

The value of C(30) represents the final cost of an item with an original cost of $30.

True – The value of C ( 30 ) represents the final cost of an item with an original cost of $ 30 .

False – The value of C ( 30 ) represents the final cost of an item with an original cost of $

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

0.038
