Because they are the same equation, just rewritten in a different way.

s = 4p

divide both sides by 4 to get the other equation:
(1/4)s = p

The point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = y minus 1 equals 1/4 left-p

Marianna [84]

The equation in point slope form is y-1 = 1/4(x - 12)

<h3>Equation of a line</h3>

The formula for calculating the equation of a line is expressed as;

y = mx + b

m is the slope

b is the intercept

Slope = 1+3/12+4

Slope = 4/16

Slope = 1/4

For the intercept

1 = 1/4(12) + b

b = 1 - 3

b = -2

Hence the equation in point slope form is y-1 = 1/4(x - 12)

What is the quotient of

ololo11 [35]

Answer:

The answer is $-2x^{9}$

Step-by-step explanation:

the quotient of -8 ÷ 4 = -2

To find the quotient of x^6 ÷ x^(-3) subtract their power

x^(6 - -3) = x^9

$\frac{-8x^{6} }{4x^{-3} }=\frac{-8}{4}(x^{6})(x^{3})=-2x^{6+3}$

$=-2x^{9}$

Minimum list price $ (10,800-14,000-11,600-6800)

3241004551 [841]

9514 1404 393

Answer:

minimum $11,600
maximum: $14,000

Step-by-step explanation:

The graph shows price decreases with age, so the minimum price will be associated with cars that are 3 years old. We read from the graph that the price of a 3-year-old car is about $11,600. (This is slightly more than halfway between the $11,000 and $12,000 grid lines.)

The maximum will be associated with a 2-year-old car. We can read the graph to find the price of a 2-year-old car is $14,000. That value is on the grid line, so no guessing is necessary.

Then we have ...

minimum: $11,600

maximum: $14,000

_____

<em>Additional comments</em>

We'd like to check our guess of the minimum using the given price equation. Filling in x=3 in the equation, we get ...

2400·3 +6800 = 7200 +6800 = 14,000 . . . . matches the maximum, not the minimum

We observe that the equation has a positive coefficient for x, so will be the equation of a rising line, not the falling one shown on the graph.

For "fun", we can check to see what the equation gives for x=2:

2400·2 +6800 = 4800 +6800 = 11,600 . . . . matches the minimum, not the maximum

This gives us some confidence that our choice of numbers is correct, but makes it clear that the equation is incorrectly written.

The problem needs to be reported, so it can be fixed.

Determine where the function is increasing, decreasing, and constant.

Rama09 [41]

Answer:

Step-by-step explanation:

How does y change as x increases over a range?

As x increases from -6 to -4, y decreases from 0 to -7

It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant

As x increases from -4 to 0, y increases from -7 to 4

It is an increasing function in this range.

For x increasing from zero, y becomes less and less

It is a decreasing function in the range larger than x = 0
