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. Then you back-solve for the first variable.

Answer:
p = 121
Step-by-step explanation:
inveresly proportional
pq² = k
find k the constant of proportionality
p is 16 when q is 11,
16 * 11² = k
k = 1,936
----------------------------
pq² = 1,936
determine p when q is equal to 4.
p * 4² = 1,936
16p = 1,936
p = 1,936/16
p = 121

Answer:
B
Step-by-step explanation:
(4π)/3 is a 3rd-quadrant angle with a reference angle of π/3 = 60°. This means both coordinates of the terminal point are negative, and the x-coordinate has the smaller magnitude. The only applicable choice is ...
B. (-1/2, -√3/2)
Answer: You can send or receive a maximum of 21 text messages per month.
Step-by-step explanation:
First, you need to take out the number the phone bill costs (24.99)
29 - 24.99 = 4.01
Then, you need to find out how many 0.19 fit into 4.01.
21 * 0.19 = 3.99. Any more than that and it would go over.
