Answer:
y = - 2x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (5, 2) into the partial equation
2 = - 10 + c ⇒ c = 2 + 10 = 12
y = - 2x + 12 ← equation of line

Answer:
$24.75
Step-by-step explanation:
Let's first add up all the costs:
![28+14+7.5 = 49.5](https://tex.z-dn.net/?f=28%2B14%2B7.5%20%3D%2049.5)
Since they split it, let's divide that by 2:
![\frac{49.5}{2} = 24.75](https://tex.z-dn.net/?f=%5Cfrac%7B49.5%7D%7B2%7D%20%3D%2024.75)
Thus, they both spent $24.75.
Answer:
510g H2S
Step-by-step explanation:
En esta pregunta, se nos pide calcular la masa de H2S emitida cuando 5 moles de sulfuro de níquel reaccionan completamente con el agua.
De la ecuación equilibrada, podemos ver que 1 mol de sulfuro de níquel produjo 3 moles de sulfuro de hidrógeno Por lo tanto, 5 moles de sulfuro de níquel producirán = 5 * 3 moles = 15 moles de sulfuro de hidrógeno
Matemáticamente, la masa se puede calcular multiplicando el número de moles por masa molar La masa molar de H2S es 2 (1) + 32 = 34 g / mol La masa en gramos así producida = 15 mol * 34g / mol = 510g
