5x+y= -5 , i hope I help you
P/9 = 90
Multiply 9 to 90 to isolate the variable.
P = 9 x 90
P = 810
25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
Answer:
y = mx+b is the equation for slope-intercept form
Step-by-step explanation:
m=slope
x=independent variable
y= y-intercept
We are not given tables, so will just use the amortization formula.

where
P=amount to be deposited today, to be found
A=amount withdrawn each year=18000
i=Annual interest=9%
n=number of years = 20
Substituting values,

=164313.82 to the nearest cent
