Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
3/2 + (-k) + (-2) =
= 3/2 + [-(-5/2)] - 2
= 3/2 + 5/2 - 2
= 8/2 - 2
= 4 - 2
= 2
300 milliliters in each container because 2.1 liters is 2100 milliliters and 2100/7 is 300
Use exp/log functions to rewrite y as
One of the properties of logarithms lets us bring down the exponent, so
Now take the derivative of both sides with respect to x. By the chain and quotient rules,
Simplify:
9: 0.8
10: 16.8
11: 0.6
12: 2.
13: 0.4
