If x=9 and y=−2, evaluate the following expression : 6x−8y

70

Step-by-step explanation:

x=9 and y=−2, evaluate the following expression : 6x−8y

plug in

6(9) - 8(-2)

= 54 + 16

= 70

The range of the function F ( x ) = | x | is:
{ y | y > 0 }
The lowest point of this function is : ( 0, 0 ). The lowest point of a new function, which is translated 6 units to the right and 2 units up is:
( 0 + 6 , 0 + 2 ) or: ( 6, 2 ).

C ) The range changes from { y | y > 0 } to { y | y > 2 } .
