The unknown is the interest rate.
The givens are the principal=$4800, time=8.5 years and amount=$8000(to find the interest, subtract the principal from the amount,$8000-$4800=$3200)so interest is $3200
The formula for finding rate is R=I*100/PT where R is rate, I is interest and P is principal and T is time.the 100 is there because R is a percentage.
R=$3200*100/$4800*8.5=7.8%(rounded to nearest tenth)
Therefore the interest rate is about 7.8%

The unknown is the interest rate.

The givens are the principal=$4800, time=8.5 years and amount=$8000(to find the interest, subtract the principal from the amount,$8000-$4800=$3200)so interest is $3200

The formula for finding rate is R=I*100/PT where R is rate, I is interest and P is principal and T is time.the 100 is there because R is a percentage.

R=$3200*100/$4800*8.5=7.8%(rounded to nearest tenth)

Therefore the interest rate is about 7.8%

Answer from: Quest

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
