Answer:

x = 1 ± [tex]\sqrt{6}[/tex]

Step-by-step explanation:

Given

2x² - 4x = 10 ( divide through by 2 )

x² - 2x = 5

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 5 + 1

(x - 1)² = 6 ( take the square root of both sides )

x - 1 = ± [tex]\sqrt{6}[/tex] ( add 1 to both sides )

x = 1 ± [tex]\sqrt{6}[/tex] ← exact solutions

Answer:

[tex]x \pm\sqrt6 +1[/tex]

Step-by-step explanation:

Hello!

Standard form of a quadratic: ax² + bx + c

Solve:

2x² - 4x = 102x² - 4x - 10 = 02(x² - 2x - 5) = 0x² - 2x - 5 = 0

Now, complete the square:

Take the b-value in our equation (-2)Divide it by 2 (-1)Square it (1)

Add and subtract that in our equation:

x² - 2x - 5 = 0x² - 2x + 1 - 5 - 1 = 0

Factor the perfect square trinomial:

(x - 1)² - 6 = 0(x - 1)² = 6[tex]\sqrt{(x-1)^2} = \sqrt{6}[/tex]x - 1 = ±√6x = ±√6 + 1

The solutions are [tex]x \pm\sqrt6 +1[/tex]

Find the distance between the points A(10,-9) and B(8,7) round your answer to the nearest hundredth

Answers

Answer:

16.12 units

Step-by-step explanation:

These two points create a right triangle whose diagonal (hypotenuse) represents the desired distance.

Going from B(8, 7) to A(10, -9) involves two steps:  Moving 2 units to the right from B(8, 7) to A(10, -9), and moving 16 steps down from B(8, 7) to A(10, -9).

Thus, the horizontal side of the triangle in question has length 2 units and the vertical side 16 units.

The length of the diagonal (which is the desired distance) is then

|AB| = +√(2^2 + 16^2) = +√(4 + 256) = +√260

To the nearest hundredth, this is |AB| = 16.12 units

Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310

Answers

Answer:

[tex]60c + 85s \geqslant 310[/tex]

Step-by-step explanation:

He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.

The required inequality:

60x + 85y >= 310

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, a person gets paid $60 to detail a car and $85 to detail an SUV.

Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.

Then, the amount earned by detailing x cars and y SUVs can be expressed as:

60x + 85y

According to the problem statement, he wants to earn at least $310, so we can write the inequality:

60x + 85y >= 310

This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

Which statement describes the graph of this polynomial function?
f(x)= x4+ x3 - 2x2
The graph crosses the x-axis at x = 2 and x = -1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = 2 and x = -1 and crosses the x-axis at x = 0.
O The graph crosses the x-axis at x = -2 and x = 1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = -2 and x = 1 and crosses the x-axis at x = 0.

Answers

Answer:

Option (3)

Step-by-step explanation:

Given function is,

f(x) = x⁴ + x³ - 2x²

     = x²(x² + x - 2)

     = x²(x² + 2x - x - 2)

     = x²[x(x + 2) - 1(x + 2)]

     = x²(x + 2)(x - 1)

So the factored form of the polynomial function is,

f(x) = x²(x + 2)(x - 1)

For x - intercepts,

F(x) = x²(x + 2)(x - 1) = 0

x = -2, 1

This function has even multiplicity = 2 at x = 0.

Therefore, graph of the function will touch the x-axis at x = 0

And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.

Option (3) will be the correct option.

What we don't know:

How many 3/4-cup servings are there?

What we should do:

Divide 6 by 3/4.

6 / 3/4

This is the same as 6 times 4/3.
