Kitty [74]
<span>The missing value that represents the rate for Marie is 1/60. As mentioned in the table, rate (r) is the part (p) per minute (t). Let's check if it works for Lea. If p = 1/80t, then r = (1/80t)/t = 1/80 * t/t = 1/80 * 1 = 1/80. So, the formula works. Now, calculate the rate for Marie. If p = 1/60t, then r = (1/60t)/t = 1/60 * t/t = 1/60 * 1 = 1/60</span>

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
