It could be isosceles or scalene. It could not be epuilateral.

Yes triangles come in different shapes and sizes and yes in some cases they can be equilateral,isosceles,and even scalene

Equation of the line contains the points (-3,2) and (5,-5)

makkiz [27]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

$(x_ {1}, y_ {1}): (- 3,2)\\(x_ {2}, y_ {2}) :( 5, -5)$

So the slope is:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-5-2} {5 - (- 3)} = \frac {-7} {5 + 3} = - \frac {7} {8}$

Thus, the equation of the line is of the form:

$y = - \frac {7} {8} x + b$

We substitute one of the points and find "b":

$2 = - \frac {7} {8} (- 3) + b\\2 = \frac {21} {8} + b\\b = 2- \frac {21} {8}\\b = \frac {16-21} {8}\\b = - \frac {5} {8}$

Finally, the equation is:

$y = - \frac {7} {8} x- \frac {5} {8}$

Answer:

$y = - \frac {7} {8} x- \frac {5} {8}$

The difference of twice a number and five is three. find the number.

Feliz [49]

Let number be x

2x - 5 = 3
2x = 3 + 5
x = 8 / 2
= 4

The number is 4

Anybody know how to do this? I need Help Now!!!!!

gogolik [260]

Hi there!

The answer is
$x \leqslant - 5$

We have the following inequality.
$- 6x \geqslant 30$

We can divide both sides by -6, but because we divide by a negative number, we must flip the sign.

$x \leqslant 30 \div - 6$
$x \leqslant - 5$
