Choose the justification for the step below. 21+7x= 14
7x= -7
a) additive property of equality
b) multiplication/division property of equality
c) distribution
d) none of these

a) additive property of equality

Step-by-step explanation:

You canceled the addition of 21 to help simplify the equation.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
