Answer:
first one
Step-by-step explanation:
The picture shows the answer I got!
Also! For the future, I use a site called
math way and it is great for problems like these.
Step-by-step explanation:
Given that the initial charge/fee for the first 5 minutes is $6
and also the additional rate per minutes is $0.6
we can model the total charges after the equation of a straight
that y= mx+c
now using the required notation
C= 0.6t+ 6
comparing this with the equation of a straight line
the constant term c is $6 flat rate for the first 5 minutes
the gradient 0.6 is m
the dependent variable x is t
and the cost C is y
Answer:
a = 
Step-by-step explanation:
Using the rule of exponents
×
=
, then
x ×
=
=
=
, so
= 
Since the bases on both sides are x, then equate the exponents.
a =
