I have no clue let me do the work and I’ll comment it under here
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
4th answer is the answer for theis question because they are equivalent
<u>Answer:</u>
Option C. The given system has two solutions.
<u>Solution:
</u>
The given equations are,
From the equation we can say,
We know that the quadratic formula to solve this,
x has two values which are
Here, a = (-1), b = 5 , c = -3
So,
Again
Hence, x has two solutions.
b)
|2x−3y| if x=0.5; y=−0.7
Substitute: |2(0.5)-3(-0.7)|
Simplify: |1+2.1|
Simplify: |3.1|
Since it is an absolute value, it will always be positive: 3.1
d)
|−3 |x| +2x−1| if x=−5
Substitute: |-3(|-5|)+2(-5)-1|
Absolute value is positive: |-3(5)+5(-5)-1|
Simplify: |-15-25-1|
Simplify: |-41|
Absolute value always positive: 41
