Answer is

C. (-8,-5)

y - y1 = m( x - x1)

so
y + 5 = 2(x + 8)?
in this case y1 = -5, x = -8

Answer:

Step-by-step explanation:

Alright, lets get started.

The equation is :

$y+5=2(x+8)$

If this line passes any point, that point must be satisfy with the equation of this line.

So, plugging the value of point (x,y) in this equation.

Once we plug (-8, -5) in the equation :

$-5+5=2(-8+8)$

$0 = 0$

It means, the point (-8, -5) is stisfying the equation of line.

So the answer is (-8, -5) option C : Answer

Hope it will help :)

Suppose you are given information about a triangle according to SSS, SAS, and ASA. For which of these can you immediately use th

jek_recluse [69]

Answer:

SSS and SAS

Step-by-step explanation:

Law of cosines: The law of cosines is used for calculating one side of a triangle when the angle opposite and the other two sides are known.

If the information about a triangle according to SSS, SAS and ASA is given, then we will immediately use SSS and SAS by using the law of cosines to find one of the remaining measures because Law of cosines is applied if we know one angle opposite and the other two sides.

Also, in ASA, we know two angles and one side, thus we cannot use Law of cosines in this, rather Law of sines can be accurately use in this case.

if you have two sides, encroaching an angle, then the Law of Cosines can be used to find a missing side, thus SAS will work fine for that, now, if you have no angles given, but you know all sides, you can use the Law of Cosines as well, by solving it for the angle, and get the angles, on which case, SSS will do... .now as far as ASA, if you have two angles and one side known, then... that's not very workable for the law of cosines

Decide whether y is a function of x. y=-3x-4

Nataly [62]

Yes, for every value of x, there is only one value of y. This means that y is a function of x.

If x = 10, y = 5, and z = 11, what is the tangent ratio for g°?

loris [4]

Please, find attached the image with the complete question

Answer:

$\large\boxed{\large\boxed{tan(g\º )=2}}$

Explanation:

The triangle ACB is a right triangle with these features:

x represents the opposite side to the angle g

y represents the adjacent side to the angle g

The tangent ratio on an angle in a right triangle is equal to the length of the leg opposite to the angle divided by the length of the leg adjacent to the angle.

Hence:

$tangent(g\º )=x/y=10/5=2\leftarrow answer$
