Answer:
b = 65
Step-by-step explanation:
b is the y- intercept
if you start to graph 6x from the two points that are already given then it'll find the y-intercept which is b
here's the graph
Select the best possible first step to solving the system by first eliminating the x variable. 3x − 9y = 6 2x − 11y = 6

Answer:
El área de la finca que está sembrada por café es 360 m².
Step-by-step explanation:
La finca de Federico tiene tiene un área de 576 m². de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:
576 m²* = 216 m²
Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:
576 m² - 216 m²= 360 m²
<u><em>El área de la finca que está sembrada por café es 360 m².</em></u>
Lets say that the two unknown integers are 
and 
.
We know the following things about and :
And, we want to find
.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:
So, given what we know about the unknown integers, the previous can be written as:
We can easily solve for:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of and , which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
