Which description is represented by a discrete graph? a. kiley bought a platter for $19 and several matching bowls that were $8 each. what is the total cost before tax? b. the temperature at 9 a. m. was 83° f and is heating up at an average rate of 6°f per hour. what is the temperature x hours later? c. juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. what is the total amount of calories he consumed? d. a bottle contained 2,000 ml of liquid and is being poured out at an average rate of 300 ml per second. how much liquid is left in the bottle after x seconds?

B

Step-by-step explanation:

it is b because it has the letter X

Option A is represented by a discrete graph.

Step-by-step explanation:

A discrete graph is a sequence of unconnected points or like scatter plots.

A. Kiley bought a platter for $19 and several matching bowls that were $8 each. What is the total cost before tax?

This is discrete because here we can see that the price for different bowls are fixed. We can count the number of bowls. This tells that the situation is not continuous.

Therefore, this situation gives a discrete graph.

Option B is a continuous graph as the temperature will change gradually.

Options C and D are not discrete as well.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
