Mathematics

BARSIC [14]3 years ago
4 0

Step-by-step explanation:

let equation be y = mx + b.

m = (9- (-3))/(-4 - 2) = -2

sub (2, -3):

-3 = -2(2) + b

b = 1

therefore equation of the line is y = -2x + 1

Are the two triangles below similar?
Hunter-Best [27]

Answer:- B) No; they do not have congruent corresponding angles.

Explanation:-

In ΔGHI ,

∠G=46° and  ∠I=27°

By angle sum property,

∠G+∠H+∠I=180°

⇒∠I=180°-∠G-∠H

⇒∠I=180°-46°-27°= 107°

In Δ JKL

∠K=108°and ∠L=27°

By angle sum property of triangles,

∠J+∠K+∠L=180°

⇒∠J=180°-∠L-∠K

⇒∠J=180°-27°-108°

⇒∠J=45°

Now we can see that there is only one pair of congruent angles [not two] in both the triangles i.e.∠I≅∠L.

⇒ They do not follow AA similarity criteria.

Thus ,the given triangles are not similar because they do not have congruent corresponding angles.

2+12a. When adding, you're only collecting "like terms".

If f(x) = x2 - 4x and f(-3), then the result is:<br> o -3.<br> O 21.<br> 0 -21.
Vladimir79 [104]
This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
