quintic means degree of 5.

a negative quintic would be: f(x) = -x⁵ <u>+              </u>

an example with one real zero could be: -x⁵ + x³ + x + 3   (see attachment)

Well let's start with y = -x^5 and y = - x^5 +1

The graph looks like the one on the right for these two.  The red one is y = - x^5 and the blue one is y = - x^5 + 1

See below on the right

You can tell that these two are correct because there is only 1 x axis intercept for each of them.  That means there is only 1 real solution which is what you are calling for.

Another one could be something like

y = -(x - 5)(x^2 + 2)(x^2 + 3)

The graph of that is on the left.

Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they hav
diamong [38]

Answer:

15 hamburgers were sold and 30 hotdogs were sold.

The systems of equations are x + y = 45 and 4x + 5y = 195.

Step-by-step explanation:

Let's make two equations.

x + y = 45

This represents the total of hotdogs and hamburgers sold

4x + 5y = 195

This represents the amount of money made for each food.

These are systems of equations, when you use 2 equations to solve a problem. I will use the strategy, Elimination for the following systems of equations. Anyways the goal is to multiply a number to x + y = 45 to cancel out one of the variables in 4x + 5y = 195. In other words, when we add these equations, the sum of the xs or ys will equal 0.

Let's multiply -5 to both x and y.

Now we have -5x -5y = -225 + 4x + 5y= 195

We will end up with -x = -30. This means that x = 30.

Now that we know x = 30, we can plug in 30 as x in one of the equations. I will plug in 30 into x + y = 45. 30 + y = 45.

Solve for y in 30 + y = 45, so y=15.

This means 15 hamburgers were sold and 30 hotdogs were sold.

2(3x+2)=6x+4 linear equations
ladessa [460]

Answer:

0 or 6x+4=6x+4  (Technically no slope at all!!)

Step-by-step explanation:

You need to do distributive property and then solve for x!!

meaning the 2(3x+2) has to get distributive property process.

6x+4=6x+4

That shall be equal together!!! (You could stop here!!)


If continue:

6x-6x=4-4

0=0

Please solve!!!!!!!!!
Likurg_2 [28]

Answer:

A

Step-by-step explanation:

Plugging (t-2) in for x, you are left with:

f(t-2)=\sqrt{4(t-2)+1}=\\\sqrt{4t-8+1}=\\\sqrt{4t-7}or answer choice A. Hope this helps!
