If f(x)=-2x-3 what is f(r+2) ?
fiasKO [112]

Answer:

f(x) =  - 2x - 3

when x is r + 2 :

f(r + 2) =  - 2(r + 2) - 3 \\  =  - 2r - 4 - 3 \\  =  - 2r - 7 \\  \\ { \boxed{ \boxed{f(r + 2) =  - 2r - 7}}}

Liam says - (5/12) is equivalent to 5/-12. Explain if Liam is correct by completing the statements below.
makkiz [27]

A positive number divided by a positive number results in a negative quotient, and it's opposite is always positive. The fraction 5/-12 can be described as a positive number divided by a negative number, which always results in a negative quotient. The fractions have different value, so Liam is not correct.
