andrew wants to purchase a new television with a screen length that is five times its width.  the width of the television screen is  7 inches  more than the width of his tablet.  andrew also wants the area of the new television screen to be at least  1,050 square inches.
if  x  is the width of andrew's tablet, determine which inequality could represent this situation.  then, determine if  8 inches  is a reasonable width for his tablet.

Part 1) The inequality that represent this situation is  or  

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

------> 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

-----> is true

therefore

Yes, 8 inches is a reasonable width for his tablet

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
