The coordinates of B and C are solutions to the system of inequalities because both are true to the two inequalities. A is not a solution to the system of inequalities because it is only true to “y is less than or equal to 2x”.
Answer:
The required amount of interest is $5538.
Step-by-step explanation:
Given : $1,500 invested for 20 days at 6.75%, compounded daily.
To find : The amount of interest ?
Solution :
Applying compound interest formula,
Where, A is the amount
P is the principal P=$1500
r is the interest rate r=6.75%=0.0675 compounded daily
t is the time t=20 days
Substitute the value in the formula,
Therefore, The required amount of interest is $5538.
First the answer is 7 but how you get it is
refine 4x+1+5x: 9x+1 and that turns into 9x+1=64
then 9x+1-1=64-1
next you do 9x/63 and that gives you 7
This one works the same way the last one did.
If -8 is x-2, then x = -6. The corresponding point is (-6, -5).
