Let's start with simplifying this equation. Typically we have y = something, so let's rewrite it in this form.
3xy = -3
y = -3/3x
y = -1/x
Alright! Now, let's go ahead and solve for the y-intercept. Those only occur when x=0, so let's plug in 0 for x.
y = -1/0
Slight problem. Dividing by a 0 results in an imaginary number, or "undefined". In this case, there is no y-intercept.
Now we can solve for an x-intercept. These only occur when y=0, so let's set y to 0!
0 = -1/x
Well shoot! We have another problem. No regular number of x will give us a y=0. However, this problem isn't the same as our undefined one from before. Here, as x value approach infinity, we get closer and closer to 0. We can never actually hit 0, but we do approach it. I'm not sure how your teacher wants it answered, but strictly, there is no x-intercept. However, we can actually attempt to explain what is going on, which is that as x go to infinity, we APPROACH y=0.
Hope that helps, and please let me know if you need clarification on anything!

Answer:
I guess A is the correct answer.
Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted
Answer:
16
Step-by-step explanation:
First, we solve for x.
We now evaluate 2-x, plugging in -14 for x.
