Answer:

x = -4.

n = -2.

v = -5.

Step-by-step explanation:

18 = -4x + 2

18 - 2 = -4x

x = 16/-4

x = -4.

6 + 2n = 2

2n = 2 - 6 = -4

n = -2.

5v + 8 = -17

5v = -17 - 8

5v = -25

v = -5.

A line passes through (3, -2) and (6,2). Write an equation for the line in point-slope form.

snow_lady [41]

Answer:

4x - 3y -18 = 0 or y = 4x/3 - 6

Step-by-step explanation:

We will have to find the slope of the line first

The formula for slope:

$m =\frac{y_{2}- y_{1} }{x_{2} -x_{1} } \\m= \frac{-2-2}{3-6}\\ =\frac{-4}{-3}\\ =\frac{4}{3}$

The standard form of equation of a line is:

y = mx + b

We know m,

So the equation will be:

$y= \frac{4}{3}x+b$

We have to find the value of b, for that we will put any one of the point in the equation

So, putting (6,2)

2 = 4/3 * 6 + b

2 = 8 +b

b = -6

Putting the value of m and b in the standard form of equation of line,

$y = mx + b\\y = \frac{4}{3}x+(-6)\\y = \frac{4}{3} x - 6\\Multiplying\ both\ sides\ by\ 3\\3y = 4x - 18\\4x - 3y -18 = 0$ ..

A product is introduced into the market. Suppose a product's sales quantity per month q ( t ) is a function of time t in months

Oksanka [162]

Answer:

$r'(t) = 298t -850$

Step-by-step explanation:

Given

$q(t) = 1000t - 150t^2$

$p(t) = 150t - t^2$

Required

$r'(t)$

First, we calculate the revenue

$r(t) = p(t) - q(t)$

So, we have:

$r(t) = 150t - t^2 - (1000t - 150t^2)$

Open bracket

$r(t) = 150t - t^2 - 1000t + 150t^2$

Collect like terms

$r(t) = 150t^2 - t^2 + 150t - 1000t$

$r(t) = 149t^2 -850t$

Differentiate to get the revenue change with time

$r'(t) = 2 * 149t -850$

$r'(t) = 298t -850$
