Answer:

below

Step-by-step explanation:

all sides are equal in rhombus

4x = 100

x = 25

diagonals bisect at right angles in rhombus

w=3

36° is alternate to right triangle where z° is there.

z+36+90= 180

z = 54°

take right triangle where y° is there

sin y = 3/10

y = 17.45°

12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se<br>¿cuál es el resultado de R(x) + S(x) ?

lesya692 [45]

Answer:

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Step-by-step explanation:

Se dan las siguientes funciones

$R(x) = -5x^2 + x - 2$

$S(x) = -x^2 - 3x$

Cuál es el resultado de R(x) + S(x) ?

Se soman los fatores en comun. Entonces:

$R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2$

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

I'm not sure what I got wrong for this question... anything may help

Answer:

Wrong: Linear functions, cubic functions

Step-by-step explanation:

Both can decrease. Cubic functions nearly always decrease at some point and, if there is a negative slope, linear functions can decrease as well.
