Answer:
R(s)
,
Step-by-step explanation:
The function R(s) = 20s
She needs to sell at least 100 subscriptions, so the least amount she wants to have is: 20*100 = $2000
Hence, is the domain of R(s) in this context
R(s)
Hope it will find you well
Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
Answer:
4.2
Step-by-step explanation:
Because RM and ML are the same, that makes KL and KR congruent. Hope his helps. :)
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
