Explain how you would factor the following equation: f(x) = xy - 5y - 2x + 10
Levart [38]

xy - 5y - 2x + 10 \\ y(x - 5) - 2(x - 5) \\  (x - 5)(y - 2)

So, F(X) = ( X - 5 ) ( Y - 2 )

When you wanna factor out some equation, try to spot things that are similar. Factoring is always a process of trial and error, but as you get more experience it will just get easier.

For example, in your question when you see y appear in many terms try to factor it out, and then produce what goes inside parenthesis.

(7x2 + 4x + 10) - (3x2 + 2x - 6)
Vedmedyk [2.9K]

Answer:

4x^2 +2x +16

Step-by-step explanation:

7x2 + 4x + 10) - (3x2 + 2x - 6)

Distribute the minus sign

7x2 + 4x + 10) - 3x2 - 2x + 6

Combine like terms

7x2 + 4x + 10)

- 3x2 - 2x + 6

-------------------------

4x^2 +2x +16

Write the equation of a sine or cosine function to describe the graph.
juin [17]

Step-by-step explanation:

The equation of a trigonometric function is

y = a  \sin(bx + c) + d

or

y = a \: cos(bx + c)  + d

Let define some variables,

D is the midline, this refers to the midpoint of the highest y value and lowest y value. Some textbooks call it the vertical translations but it is the same thing.

A is the amplitude. The amplitude is the distance from the midline to the highest y value. Some distance is non negative, the formula for the amplitude is

|a|

The period is how often the wave repeats itself on a interval.

Period can't be negative so the formula for period is

\frac{2 \pi}{ |b| }

To find the period, look at the extreme points.

The phase shift tells us if the sinusoid have been shifted to the right or left. The formula for the phase shift

bx + c = 0

Solving for x gives us

x =  \frac{  - c}{b}

If our x is negative, we have a phase shift to the right

If our x is Positve, we have a phase shift to the left.

Let solve this equation, Let use Sine since sin(0)=0,

The smallest y value here is 0, and the highest is 2, so the amplitude is 1.

d = 1

Next, the distance from the max to the midline is 1, as well the min to the midline is also 1.

So

a = 1

We have minimum at 0, and 8, so our period is 8.

\frac{2\pi}{b}  = 8

Solve for b,

\frac{\pi}{4}  = b

Plug this in the equation.

1 \sin( \frac{\pi}{4} x)  +

y =  \sin( \frac{\pi}{4} x)  + 1

The graph passes through (4,2) so let see if that holds true for our equation

2 =  \sin( \frac{\pi}{4} (4))  + 1

2 =  \sin(\pi)  + 1

2 = 0 + 1

2 = 1

This doesn't hold true, so we must have a phase shift

Notice that

\sin( \frac{\pi}{2} )  = 1

So if we shift this pi/2 to the right, we can get our equation to be true.

y =  \sin( \frac{\pi}{4} x -  \frac{\pi}{2} )  + 1

This equation works so our equation is

y =  \sin( \frac{\pi}{4} x -  \frac{\pi}{2} )  + 1
