How do I factor the following equation in the link? It has been factored, but I need to know the steps.
Vlad [161]

Given

2x^2-x-3=0

How to factor

Solution

Step 1

Multiply the first and last costant

-3\times2x^2=-6x^2

Step 2

Write out all the pair factors of -6x^2

\begin{gathered} -6x^2=-6x\text{ and x} \\ -6x^2=-x\text{ and 6x} \\ -6x^2=\text{ -3x and 2x} \\ -6x^2=\text{ -2x and 3x} \end{gathered}

Step 3

Check for the pair, such that when you add you will get -x

\begin{gathered} it\text{ is } \\ -3x+2x=-x \\ \therefore-3x,\text{ 2x} \end{gathered}

Step 4

Replace -x with -3x+2x in the equation

2x^2-3x+2x-3=0

Step 5

Put them into brackets Since + is at the center no stress.

(2x^2-3x)+(2x-3)=0

Step 6

Factor out what is common in the bracket

x(2x^{}-3)+1(2x-3)=0

Step 7

What is in the bracket are the same, pick one

\therefore(2x-3)(x+1)=0_{}

A plane leaves the airport at 9:15pm and travels at a speed of 560km/h. how far will it be at midnight?
lidiya [134]

A plane leaves the airport at 9:15pm and travels at speed 560km/h then at midnight plane will be at 1540 km far away.

As given,

Plane leaves the airport at 9:15 pm

Plane travels at speed of 560 km /h

Total time = 2hour+ 45minutes

               = 2hour+ (45/60)hour

               = (11 /4) hour

We have

1 hour = 560 km

⇒ (11 /4)hour = (560 ×11)/4 km

                     = 1540 km

Therefore, a plane leaves the airport at 9:15pm and travels at  speed 560km/h then at midnight plane will be at 1540 km far away.

Issouf claims that the scale factor is 1/2. which statement about his claim is correct?
love history [14]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

CB'=C'B'=2

B'B=6

CB=CB'+B'B=2+4=6

The scale factor of a figure is

k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}

k=\frac{C'B'}{CB}

k=\frac{2}{6}

k=\frac{1}{3}

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.
