The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=200−0.4x is
amid [387]

Answer:

maximum revenue is 25000

Step-by-step explanation:

The revenue function for a bicycle shop is given by R(x)=x⋅p(x)

Given p(x)= 200-0.4x

R(x)=x \cdot p(x)

Plug in p(x) in R(x)

R(x)=x \cdot 200-0.4x

R(x)=200x-0.4x^2

Now find out the vertex using formula x=-b/2a

a= -0.4, b=200

x=\frac{-b}{2a} =\frac{-200}{2(-.4)} =250

Plug in 250 for x  in R(x)

R(x)=200x-0.4x^2

R(x)=200(250)-0.4(250)^2=25000

So maximum revenue is 25000

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
Sav [38]

Answer:

y=4x+31

your answer will have a line that

3 is your y-intercept located at your y-axis

and 4x your slope.

we start from our point on the y-axis 31

and rise/run

rise over run = 4/1

rise 4

run 1

so move up 4

and to the right 1

Step-by-step explanation:

Since there is no image for me to tell you which line it is you can easily find out by chancing this expression to y=mx+b form. also known as slope intercept form.

y-3=4(x+7)

we want to do order of operations. pemdas

so first we do Parenthesis to do so we need to distribute the 4.

after we do so we get...

y-3=4x+28

now we need to move -3 to isolate y

to do so we need add 3

y=4x+31

Can someone help me out with this? I’m not sure what I’m doing wrong.
Nadusha1986 [10]

Answer:


Step-by-step explanation:

This is a system of inequalities such that:

\left \{ {{2x+3y\geq 2} \atop {3x-4y\leq 3}} \right.

Let's start by solving for y for both equations:

Equation 1:

2x+3y\geq  2\\\\3y\geq -2x+2\\\\y \geq \frac{-2x+2}{3}

Equation 2:

3x-4y\leq 3\\\\-4y\leq -3x+3\\\\y\geq -\frac{(-3x+3)}{4}


Now if we substitute the 2nd y into the first equation we obtain:

2x+3(\frac{3x-3}{4}) \geq  2\\\\2x+\frac{9x-9}{4}\geq 2\\\\\frac{8x+9x-9}{4}\geq 2\\\\17x-9\geq 8\\\\17x\geq 17\\\\x\geq 1


Now we will solve for the second equation using the first result of y and we obtain:

3x-4(\frac{-2x+2}{3}\leq 3\\\\3x+\frac{8x-8}{3}\leq 3\\\\\frac{9x+8x-8}{3}\leq 3\\\\17x-8\leq 9\\\\17x\leq 17\\\\x\leq 1

And so our solution for the system of equations is:

x \leq 1\\and \\y\geq \frac{-2x+2}{3}

As well as:

x>1\\and\\y\geq \frac{3x-3}{4}
