4.3     Solving    3x2+14x+16 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     3

                     B   =    14

                     C   =   16

Accordingly,  B2  -  4AC   =

                    196 - 192 =

                    4

Applying the quadratic formula :

              -14 ± √ 4

  x  =    —————

                   6

Can  √ 4 be simplified ?

Yes!   The prime factorization of  4   is

  2•2  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4   =  √ 2•2   =

               ±  2 • √ 1   =

               ±  2

So now we are looking at:

          x  =  ( -14 ± 2) / 6

Two real solutions:

x =(-14+√4)/6=(-7+)/3= -2.000

or:

x =(-14-√4)/6=(-7-)/3= -2.667

Answer:

If simplifying, then

x^3 -13x^2 -x -49

Step-by-step explanation:

To do this, I would start off with the left side (use PEMDAS)

Use FOIL (First, Outside, Inside, Last)

x^3 + -9x^2 + 6x + -54 - (4x^2 + 7x - 5)

Bring negatives inside parenthesis

x^3 -9x^2 +6x -54 -4x^2 -7x +5

Combine like-terms

x^3 -13x^2 -x -49

(x^2 +6)(x-9)-(4x^2 +7x-5)

x^2 + 6 * x - 9 - 4x^2 - 7x + 5

x^2 + 6x - 9 - 4x^2 - 7x + 5

(x^2 - 4x^2) +(6x - 7x)+(-9 + 5)

(-3x^2)+(-x)+(-4)

=-3x^2 -x - 4

Question:

Which description could be written as a linear function?

Answer:

Option a)

Explanation:

Let 2 numbers be x1 and x2.

For the first option:

Eight more than twice a number.

The graph would be y = 8 + 2x1 which is a linear function.

For the second option:

Three more than the product of two numbers.

The graph would be y = 3 + x1x2 which is a graph function.

For the third option:

Ten more than the square of a number.

The graph would be y = 9 + (x1)² which is a graph function.

For the fourth option:

Nine more than one divided by a number.

The graph would be y = 9 + 1/x1 which is a double-parabole function.

Hopefully this answer will help you.

Answer:

It's proved below

Step-by-step explanation:

We are given;

- K is the midpoint of JL

- M is the midpoint of LN

By definition of mid points, we can say that;

JK = KL and LM = MN

Now, we are given that JK = MN.

Thus, by substitution, we can deduce that; KL = LM

Thus is because JK can be replaced with KL and MN can be replaced with LM.

Thus, it is proved that KL = LM

Answer:

x = 20

Step-by-step explanation:

Let's look at the first parallel lines (the ones with one arrow).

Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.

So we have to make both of these expression equal to each other, and then solve:

3x + 2 = 4x - 18

-x = - 20

x = 20            < --- this is your answer

Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

unit price of something is price of 1 thing.

LEts suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

Given that Caleb paid $4.50 for 12 bagels.

Unit price = 4.50 / 12 = 0.375

A) $2.25 for 6 bagols

Unit price = 2.25 / 6 = 0.375

B) $13.50 for 10 bagels

Unit price = 13.50 / 10= 1.35

c) $3.30 for 6 bagols

Unit price = 3.30 / 6 = 0.55

D) $5.00 for 12 bagets

Unit price = 5.00 / 12 = 0.41

E) $8.10 for 18 bagels

Unit price = 8.10 / 18 = 0.45

Hence, Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.
