Answer: y - 4x = 9 <em>in standard form is</em> -y + 4x = -9
Answer:
It is -4 :)
Step-by-step explanation:
I just did this lol
Answer: -89
Step-by-step explanation:
So your equation is
- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)
You know that (a) (b) and (c) = -1
You also know that (x) and (y) = 7
So, when you put this into the equation, it will look like this:
- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)
When you work that out you will get left with your answer, which is -89.
HOPE THIS HELPS!!!
For this case we have an equation of the form:

Where,
A: initial amount
b: growth rate
t: time in years.
Substituting values we have:

By the time the population is triple we have:

Rewriting we have:

Clearing t we have:
Answer:
It will take for the population to triple about:
t = 73 years
Answer:
measure of two unknown angles are 35.7° and 75.4°
measure of one unknown side is 16.6 inches
Step-by-step explanation:
i used law of sines to find the angle opposite 10 inch side
sin 68.9/16 = sinФ/10
Ф = 35.7°
then is added 35.7 and 68.9 and subtracted the sum from 180° to get the measure of the third angle, 75.4°
i used law of sines again to find the measure of the third side
sin 68.9/16 = sin 75.4/x
x = 16.59
