Asap! 20 points! !

there are approximately 400 million trees currently growing in the amazon rainforest, which covers approximately 5.5 million square kilometers. the rainforest is being cleared at a rate of 20,000 square kilometers per year to make way for new farmland and to harvest wood for building supplies. before this year, 250,000 square kilometers had already been cleared. a preservation consortium is trying to mitigate the loss of rainforest by planting new trees. they have already planted 3,000 square kilometers of trees and plan to plant 100 square kilometers of trees each year.

how can you enter this into a graphing calculator?

what area will have been cleared due to deforestation after 1 year, 5 years, and 10 years in sq km?

400 million trees in 5.5 million square km

clearing rate: 20,000 square km per year.

250,000 square km has already been cleared. 

Already planted 3,000 square km

plant 100 square km of trees per year

Create an equation to represent the rainforest area deforested, AD, in thousands of square kilometers, after t years.

AD = 20,000km²(t) + 250,000km²

Create an equation to represent the rainforest area planted with new trees, AP, in thousands of square kilometers, after t years.

AP = 100km²(t) + 3,000 km²

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

is this part of a question or something
