Answer:

B

Step-by-step explanation:

A is wrong, it increases

C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.

D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )

What is 6/a-6 = 3/a-3 ?<br> help me please
Alenkasestr [34]

Answer:

a=1

Step-by-step explanation:

Multiply all terms by a and cancel:

6+−6a=3+−3a

−6a+6=−3a+3(Simplify both sides of the equation)

−6a+6+3a=−3a+3+3a(Add 3a to both sides)

−3a+6=3

−3a+6−6=3−6(Subtract 6 from both sides)

−3a=−3

−3a

−3

=

−3

−3

(Divide both sides by -3)

a=1
