Answer:
wait whats the question-
Step-by-step explanation:
Answer:
The slope is -2 full equation is y = -2x -2
Answer:
Part 1) The inequality that represent this situation is
or ![5x^{2}+70x+245 \geq1,050](https://tex.z-dn.net/?f=5x%5E%7B2%7D%2B70x%2B245%20%5Cgeq1%2C050)
Part 2) Yes, 8 inches is a reasonable width for his tablet
Step-by-step explanation:
Part 1)
Let
L -----> the length of the screen television
W ----> the width of the screen television
x ----> the width of Andrew's tablet
we know that
------> equation A
----> equation B
The area of the television is
-----> equation C
Substitute equation A and equation B in equation C
![A=5(x+7)^{2}](https://tex.z-dn.net/?f=A%3D5%28x%2B7%29%5E%7B2%7D)
------> inequality that represent this situation
Part 2) Determine if 8 inches is a reasonable width for his tablet
For x=8 in
Substitute in the inequality
![5(8+7)^{2} \geq1,050](https://tex.z-dn.net/?f=5%288%2B7%29%5E%7B2%7D%20%5Cgeq1%2C050)
![5(15)^{2} \geq1,050](https://tex.z-dn.net/?f=5%2815%29%5E%7B2%7D%20%5Cgeq1%2C050)
-----> is true
therefore
Yes, 8 inches is a reasonable width for his tablet
10 miles=52800 feet (I know for sure)
