Answer:
dC/dt = 2 mg*cm³/s
Step-by-step explanation:
Given
C(t)= (1/2)*(4t+ 4)- (1/2)
we apply dC/dt as follows
dC/dt = d((1/2)*(4t+ 4)- (1/2))/dt = (1/2)*(4) = 2
⇒ dC/dt = 2 mg*cm³/s
so hmmm on average on the last 7 test, you get 82, so hmmm we could say that on each of the 7 tests you got 82, so you got 82, 7 times.
now, let's say in the 8th test, you get a grade of "g", now, if we were to get an average of all 8 tests, that means the average will simply be (82*7) + "g", and we know that's 84, so

I can help you with something else ??
<span>For each one . . .
=> solve the
equation for 'y'. That means massage it around until it's
in the form
of <em> y</em> = (thing1) <em>x</em> + (thing2).
=> When you do that, then 'thing1'
is the slope of the line on the graph,
and 'thing2' is the number
where the line crosses the y-axis.
=> When you have those two
numbers, drawing the line on the graph
is a piece-o-cake.</span>
