Answer:

(x - 7)(x - 2)

Step-by-step explanation:

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 7 and - 2, since

- 7 × - 2 = + 14 and - 7 - 2 = - 9, hence

x² - 9x + 14 = (x - 7)(x - 2) ← in factored form

$x^2-9x+14 =x^2-2x-7x+14=x(x-2)-7(x-2)=(x-7)(x-2)$

What is the inverse of the given relation? y = 4x - 8

Aleks [24]

Let y be x, and x be y.

x = 4y - 8

Rearrange to make y the subject.

x + 8 = 4y

Therefore

y = (x + 8) / 4

is the inverse.

What two numbers add to 10 and multiply to -192? How do you find it?

Levart [38]

There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative.
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum.
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this.

The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.

What is the slope of a line perpendicular to the line whose equation is 3x + y = -9.

Harrizon [31]

Considering the definition of perpendicular line, the slope of a line perpendicular to the line whose equation is 3x+y= -9 is $\frac{1}{3}$ .

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point.
m is the slope.
b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Perpendicular line</h3>

Perpendicular lines are lines that intersect at right angles or 90° angles.

Two nonvertical lines are perpendicular if the slope of one is the negative reciprocal of the slope of the other. In other words, if you multiply the slopes of two perpendicular lines, you get –1.

<h3>Equation of perpendicular line in this case</h3>

In this case, the line is 3x+y=-9. Expressed in the form y = mx + b, you get: y= -9 - 3x or, what is the same, y= -3x -9

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of -3. So:

(-3)× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (-3)

<u><em>slope perpendicular line= </em></u> $\frac{1}{3}$

Finally, the slope of a line perpendicular to the line whose equation is 3x+y= -9 is $\frac{1}{3}$ .
