Write the equation of a line that is perpendicular to y=-2/7x + 9 and that passes through the point (-4,6) [FP]​
siniylev [52]

Answer:

$y=(7/2)x+20$

Step-by-step explanation:

SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.

Therefore by the point slope formula the line that we are looking for is

$y-6=(7/2)(x+4)$

$y=(7/2)x + 20$

The demand function Q and cost function C(Q) of a commodity are given by the equations \[ Q = 20 - 0{,}01P\]
BartSMP [9]

The total revenue of the function is the product of the quantity and the price

The total revenue in terms of P is TR = 20P - 0.01P^2

<h3>How to determine the total revenue?</h3>

The demand and the cost functions are given as:

Quantity function, Q = 20 - 0.01P

Cost function, C(Q)=60+6Q

The total revenue is calculated as:

TR = Q * P

Substitute Q = 20 - 0.01P in the above equation

TR = P * [20 - 0.01P]

Evaluate the product

TR = 20P - 0.01P^2

Hence, the total revenue in terms of P is TR = 20P - 0.01P^2

A customer borrowed $2000 and then a further $1000 both repayble in 12 months. What would he have saved if he had taken out one
RSB [31]

A customer borrowed $2000 and then a further $1000 both repayble in 12 months. What would he have saved if he had taken out one loan for $3000 repayable in 12 months?

He took two different loans, it charged him loan processing fee twice, two-time documentation process, and of course, extra time spent for second loan. Instead, he could take single loan of $3000 with one-time processing fee, one-time documentation process, and time-saving also.

The slope-intercept equation is y=mx+b.

The slope formula is \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes \frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, y=\frac{6}{5}x-1. When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we gety=\frac{6}{5}x-1.
