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:
The balance after 37 years is $3869.99
Step-by-step explanation:
<u>Given:</u>
- Principal (P) = $2,520
- Rate of Interest (R) = 1.16%
- Time (t) = 37 years
- Compounds Interest Monthly (n) = 12
The Amount (A),
A = P (1 + <em> if compound n times per year</em>
Amount (A) at 37 years,
A = ($2,520) (1 +
A = ($2,520) (1 +
A = ($2,520) (1.00096667
A = ($2,520) (1.5357)
A = $3869.9944

Answer:
A)cosx(4sinx-1)=0
Step-by-step explanation:
The given equation is
We equate everything to zero to get:
Use the double angle property, to get:
This implies that:
The correct answer is A
By process of elimination. 3y and -3y get eliminated. Giving you
3x=18
Divide by 3 on each side
Giving you x=6
Plugging it into equation 2 you get
(6)-3y=3
Taking out the parenthesis you have
6-3y=3
Subtract by 6 on each side giving you
-3y=-3
Divide by -3 on each side giving you
y=1
So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)
