Answer:
1. C, 2.C
Step-by-step explanation:
Here's why for the first one it's easy because we just solve y=2, x=3, so we select C, the next one however we have to know eliminate a variable, which in this case we can eliminate the y variable quite easily. So once we did that we got x=2, now we plug that in to the first equation and we get -y=1, which is equal to -1.

Answer:
0.6
Step-by-step explanation:
La fórmula para calcular la probabilidad de dos eventos se da como:
P (A⋃B) = P (A) + P (B) - P (A ⋂ B)
De la pregunta, sabemos que:
Probabilidad de que Carlos haya comido pollo frito: P (C) = 0.4.
Probabilidad de que Carlos coma una hamburguesa para el almuerzo: P (H) = 0.3.
Probabilidad de que Carlos almorce pollo frito y hamburguesa el mismo día: P (C ⋂ H) = 0.1.
Probabilidad de que Carlos coma pollo frito o hamburguesa para el almuerzo:
P (C ⋃ H) =?
Por lo tanto, aplicando nuestra fórmula:
P (C ⋃ H) = P (C) + P (H) - P (C ⋂ H)
P (C ⋃ H) = 0.4 + 0.3 - 0.1
P (C ⋃ H) = 0.6
Answer:
