The range is the y values that can be gotten from inserting the domain
we will assume the domain to be all real numbers

when x approahces infinity, y approaches inifnity
when x approaches negative inifnity, y appraoches negative infinity

no holes
range is all real numbers

What is the equation, in slope-intercept form, of the line that is perpendicular to the line

NeTakaya

Answer:

y = -x - 4

Step-by-step explanation:

First find the slope

y - 4 = (x - 6)

y - 4 = x - 6

y = x - 6 + 4

y = x - 2 (y = mx + C)

Slope m = 1

It is said that the line is perpendicular to a point ( -2, -2)

If two lines are perpendicular, their slope will be negative reciprocal

The negative reciprocal of slope = 1 is -1

Using a slope intercept form as requested by the question

y = mx + C

Inserting the values given

(-2, -2)

We are using point slope form

y - y_1 = m ( x - x_1)

x_1 = -2

y_1 = -2

m = -1

Insert the values

y - ( -2)) = -1( x - (-2))

y + 2 = -1 ( x + 2)---- point slope form

But we are requested to give the answer in slope intercept form

y = mx + C

We have to open the bracket

y + 2 = -1(x + 2)

y + 2 = -x - 2

y = -x - 2 - 2

y = -x - 4 ( slope - intercept form)

If 8 is subtracted from 7 times a number the result is 34

djverab [1.8K]

7x - 8 = 34

Solving:

7x = 34 + 8
7x = 42
x = 6

13+x+195=13(x+15)...

LUCKY_DIMON [66]

First, let's expand the right side. Now our equation is

$13+x+195=13x+195$

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

$-12x=-13$

And then we can make this

$12x=13$

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
