Answer:
x = 20.75
Step-by-step explanation:
<u>Step 1: Solve for x</u>
4x + (-9) = 74
4x - 9 + 9 = 74 + 9
4x / 4 = 83 / 4
x = 20.75
Answer: x = 20.75
Answer:
d)9991.15
Step-by-step explanation:
We have a sum of money ($6000) compounded daily at an annual interest rate of 8.5% for 6 years.
If the interest is compound daily, and we take a m=365 days a year (or 365 subperiods m), the daily nominal interest rate is:
Then, we can express the final valueo of $6000 compounded daily at an annual interest rate of 8.5% for 6 years as:

Exponents allow for shorter, more concise answers. Say you needed to state the number 88,209. 9^5 is a much shorter number, and still gets the point across.
Answer:
X = -7 and y = -7.5
Step-by-step explanation:
Use substitution. Let’s try to get x by itself in the second question since it seems easier.
-4x + 4y = -2
-4x = -2 -4y
x = 1/2 + y
Subsitute that into the other equation for y.
4x -2y = -13
4(1/2 + y) - 2y = -13
2 + 4y -2y = -13 # Use the distributive property
2y = -15 # put together like terms
y = -7.5
Then plug it into the x formula
x = .5 -7.5
x = -7
