Answer:

Step-by-step explanation:

(-2 , 3) & (-8 , 1)

Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{1-3}{-8-[-2]}=\dfrac{1-3}{-8+2}\\\\=\dfrac{-2}{-6}\\\\=\dfrac{1}{3}

m1 = 1/3

Slope of the perpendicular line to the given line = -1/m1 = -1 ÷ \frac{1}{3} = -1*\frac{3}{1}=-3

Equation of the perpendicular line: y =mx +b

y = -3x + b

Plugin x = -5 & y =1

1 = -3*(-5) + b

1 = 15 + b

1 - 15 = b

b = -14

Equation of the line :  y = -3x - 14

Jim sells used drones for 70% of the original manufacturer's purchase price of a new drone. Jim also sells new drones for 15% mo
adell [148]

The function for the amount saved if they purchase a used drone rather than a new drone from Jim's store is f(x) = 0.45x

He sells used drones at 70% of the price (x).

So, the selling price of a used drone is:

\mathbf{Used = 70\% \times x}

Express percentage as decimal

\mathbf{Used = 0.7 \times x}

\mathbf{Used = 0.7x}

Also, he sells new drones at 15% more of the price (x).

So, the selling price of a new drone is:

\mathbf{New= (1 + 15\%) \times x}

Express percentage as decimal

\mathbf{New= (1 + 0.15) \times x}

\mathbf{New= 1.15 \times x}

\mathbf{New= 1.15x}

The amount saved is the difference between the prices of the drones.

So, we have:

\mathbf{Saved =New - Old}

This gives

\mathbf{Saved =1.15x- 0.7x}

Subtract

\mathbf{Saved =0.45x}

Express as a function

\mathbf{f(x) = 0.45x}

Hence, the function for the amount saved is f(x) = 0.45x
