Answer:

x = 6.5

Step-by-step explanation:

* since it's a triangle ALL the angles inside should give you 180° * Equate everything to 180°

8x + 10x - 10°+ 10x + 8° = 180°( sum of angles on a triangle)

28x - 2° = 180° * group like terms*

28x = 182°

x = 6.5

Given the midpoint and one endpoint of a line segment , find the other endpoint. Endpoint: (10, 12), midpoint: (6, 9)

aleksandr82 [10.1K]

The other end-point is: (2,6)

Step-by-step explanation:

Let the end-points be:

$(x_1,y_1)\ and\ (x_2,y_2)$

(x1,y1) = (10,12)

Mid-point = M = (6,9)

The formula for mid-point is given by:

$M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Putting the values

$(6,9) = (\frac{10+x_2}{2} , \frac{12+y_2}{2})$

Putting respective coordinates equal

$6 = \frac{10+x_2}{2}\\6*2 = 10+x_2\\12 = 10+x_2\\x_2 = 12-10\\x_2 = 2\\9 = \frac{12+y_2}{2}\\9*2 = 12+y_2\\18 = 12+y_2\\y_2 = 18-12\\y_2 = 6$

The other end-point is: (2,6)

Draw the graph of the equation

guapka [62]

9514 1404 393

Answer:

24 square units

Step-by-step explanation:

The triangle is a right triangle with legs 6 and 8. Its area is ...

A = 1/2bh = 1/2(6)(8) = 24 . . . . square units

_____

<em>Additional comment</em>

The equation for a line in <em>intercept form</em> is ...

x/a + y/b = 1

where 'a' and 'b' are the x- and y-intercepts, respectively. If we divide the given equation by 2, we get ...

x/6 +y/8 = 1

showing us that the x- and y-intercepts are 6 and 8. This is also clear on the graph.

What is the domain of the function f(x) = x + 1/ x^2 - 6 + 8?

dangina [55]

Answer:

The domain is all values but x=4 and x=2

Step-by-step explanation:

f(x) = (x+1) / ( x^2-6x+8)

Factor the function

f(x) = (x+1) / ( (x-4) ( x-2))

The domain of the function is all values of x except where the function does not exist

This is where the denominator goes to zero

(x-4) ( x-2) =0

Using the zero product property

x-4 =0 x-2 =0

x=4 x=2

The domain is all values but x=4 and x=2

Identify the horizontal asymptote of f(x) =x2+5x-3/4x-1

Pachacha [2.7K]

since the numerator is x² + 5x - 3, and therefore has a degree of 2, whilst the denominator, 4x¹ - 1, has a degree of 1, therefore, there's no horizontal asymptote.

recall, we only get a horizontal asymptote if the denominator's expression degree is equals or greater than that of the numerator's.
