Answer:

-x^2+10x+7

Step-by-step explanation:

3x^2+8x+7-(4x^2-2x). find the difference of the polynomials

First remove the parenthesis by multiplying minus inside the parenthesis.

3x^2+8x+7-4x^2+2x

Now we combine like terms. the terms with same variables and same exponents are like terms.

3x^2-4x^2= -1x^2

8x +2x= 10x

3x^2+8x+7-(4x^2-2x)=-x^2+10x+7

Find the inverse function
Alex

The inverse of this function is f(x) = \frac{3x + 15}{4}


To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.


f(x) = \frac{-15 + 4x}{3} ----> Switch the x and f(x)


x = \frac{-15 + 4f(x)}{3} ----> Muliply both sides by 3


3x = -15 + 4f(x) ----> Add 15 to both sides


3x + 15 = 4f(x) ----> Divide both sides by 4.


f(x) = \frac{3x + 15}{4}

A roped-off area of width x is created around a 30- by 10-foot rectangular museum display of Native American artifacts. The comb
Monica [59]

Answer: 4x^{2}+80x-500=0

Step-by-step explanation:

1. You know that:

-  The roped-off area whose width is represented with <em>x,</em> it is created around  a rectangular museum.

- The dimensions of the rectangular museum are: 30 ft by 10 ft.

- The combined area of the display and the roped-off area is 800 ft².

2. The area of the rectangular museum can be calculated with:

A=l*w

Where l is the lenght and w is the width.

You have that the lenght and the width in feet are:

l=30\\w=10

3. Let's call x the width of the roped-off area. Then, the combined area is:

A_c=l_c*w_c

Where

A_c=800

l_c=l+x+x=30+2x

w_c=w+x+x=10+2x

4. Substitute values and simplify. Then:

 800=(30+2x)(10+2x)

800=300+60x+20x+4x^{2}\\4x^{2}+80x-500=0

Lindsay and menonhave 1,240 stickers.menon has 4 times as many stickers as Lindsay.menon decides to have 6 stickers on each page
Lemur [1.5K]

a) Menon has 992 stickers. We can find this by writing an algebraic expression for the number of stickers, with x being the number that Lindsay has. This gives us:

x + 4x = 1240

5x = 1240

x = 248

Now we multiply 248 by 4 to get 992.

b) There are 2 stickers left over. First we have to divide 992 by 6, which gives us 165 as a whole number, but then a remainder of 2. That means that there are two stickers left.

c) Menon needs 4 more stickers, as 6 - 2 = 4, and there are 6 stickers per page.

I hope this helps! Let me know if you have any questions :)
