First, combine 20c and 10c because they are like terms then combine 8d and -5d.
It would look like this:
20c+8d+10c-5d
30c+3d
Hope that helps
Answer:
y-intercept: (0,-3)
Step-by-step explanation:
- Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:
- Therefore, the point is (0,-3).
hey, I'm not sure about this answer, but I think it's true, sorry
m(2g+5mk)
Answer:
62
Step-by-step explanation:
Plug in the value of a in the equation:
12(4) - 6 + 7(4) - 2(4)
Solve 12(4) - 6:
12(4) - 6 = 48 - 6 = 42
Solve 7(4) - 2(4):
7(4) - 2(4) = 28 - 8 = 20
Combine both answers (42+20):
42+20 = 62
Complete answer:
12(4) - 6 + 7(4) - 2(4) = 62
For this case we have the following function:
n (t) = 2400 * (5) ^ t
For n (t) = 60000 we have:
60000 = 2400 * (5) ^ t
We clear the value of t.
For this we use the logarithm:
(5) ^ t = 60000/2400
log5 ((5) ^ t) = log5 (60000/2400)
t = log5 (60000/2400)
t = 2 days
Answer:
the number of bacteria in the culture will be 60 comma 000 after:
t = 2 days
