Answer:
The value of r to be out in the given formula is r = 0.048.
Step-by-step explanation:
The rate is given as 4.8%.
Now to put the value of interest in the given formula,
We need the value of r.
r = 
Hence, the value of r to be out in the given formula is r = 0.048.
Answer:
x=3, y=8; (3,8)
Step-by-step explanation:
To use the substitution method, first solve for a variable.
2x+y=14
2x+y(-2x)=14(-2x)
y=14-2x
Now substitute y in the other equation with 14-2x
5x-2(14-2x)= - 1
Simplify by multiplying inside the parenthesis.
5x-28+4x= - 1
Combine the x values
9x-28= - 1
9x=27
x=3
Now substitute the x value in to solve for y
2(3)+y=14
6+y=14
y=8
Y=9/4x-5 is the standard form.
