Which best describes your ability to write a linear equation in standard point slope and slope intercept form

Answer:

There are many ways to describe a linear equation:

standard form: Ax + By = C, where x-intercept point is C/A and y-intercept point is C/B

point slope form: y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line

slope intercept form: y = mx + b, where m is the slope and b is the y-intercept

All of them can describe any linear equation,  which is best depends on what data you have. For example if you have the interceptions with the axis, use the standard form; if you have any two points (x2, y2) and (x3, y3), compute the slope as: m = (y3 -y2)/(x3 - x2) and use the point slope form. And always you can transform one form into another one; continuing with the last example, if you have the point slope form, you can isolate y as: y = mx - mx1 + y1, to get  the slope intercept form (b = - mx1 + y1).

Round your answer to the nearest hundredth AC=
KatRina [158]

Answer:

AC ≈ 2.96

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos65° = \frac{adjacent}{hypotenuse} = \frac{AC}{AB} = \frac{AC}{7}

Multiply both sides by 7

7 × cos65° = AC , thus

AC ≈ 2.96 ( to the nearest hundredth )

Is y=10.2x a proportional relationship?​
BabaBlast [244]

Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2

A store has been selling 300 Blu-ray disc players a week at $600 each. A market survey indicates that for each $40 rebate offere
timurjin [86]

Answer:

75 $

Step-by-step explanation:

According to problem statement p(300) = 600

And we know that with a rebate of 40 $, numbers of units sold will increase by 80 then if x is number of units sold, the increase in units is

(  x  - 300 )  , and the price decrease

(1/80)*40  =  0,5

Then the demand function is:

D(x)  =  600  - 0,5* ( x - 300 )  (1)

And revenue function is:

R(x) =  x * (D(x)   ⇒   R(x) =  x* [  600  - 0,5* ( x - 300 )]

R(x) = 600*x  - 0,5*x * ( x - 300 )

R(x) = 600*x - 0,5*x² - 150*x

R(x) = 450*x  - (1/2)*x²

Now taking derivatives on both sides of the equation we get

R´(x) =  450  - x

R´(x) =  0       ⇒   450  - x = 0

x = 450 units

We can observe that for   0 < x  < 450  R(x) > 0 then R(x) has a maximum for x = 450

Plugging this value in demand equation, we get the rebate for maximize revenue

D(450)  =  600  - 0,5* ( x - 300 )

D(450)  =  600 - 225 + 150

D(450)  =

D(450)  =  600 - 0,5*( 150)

D(450)  =  600 - 75

D(450)  = 525

And the rebate must be

600 - 525  = 75 $
