Yes, that is correct but what is your question???
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
solve for P
The answer would be x= 4,-4
Answer:
27
Step-by-step explanation:
30% of 90 can be written as 30% × 90
= 30/100 × 90
= 27
Answer:
y = 
Step-by-step explanation:
Standard equation in point slope form is :
y-y_0 = m(x-x_0) +c
where m = slope = -1/2
(x_0,y_0) is the point from which the lines passes through = (5,-3)
We get the equation as,
y-(-3) = -1/2(x-5)
y+3 =
(x-5)
y = 
y = 
Hence, m= -1/2 and c = -1/2
Required equations is:
y =
