What is the y intercept of the line -9x+3y=18


y = 6

hope this helps

Answer: (0, 6)

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Question is −9x + 3y = 18

Our first step would be is to find y which will be done by 3y = 18.

Part 1

Step 1: Enter y equation.

3y = 18

Step 2:Simplify.

y = 6

Now that we have our y, we need to find our X. We can do this by plugging in y, which is 6 into the equation to find X.

Part 2

Step 1: Enter the X equation by plugging in y.

−9x + 3(6) + 18

Step 2:Simplify.

−9x + 18 = 18

Step 3:Simplify.

−9x = 18 − 18

Step 4:Simplify.

(-9x)/(-9)  = (0)/(-9)

Step 5: Simplify.

x = 0

Because 0 is our X coordinate and 6 is our Y coordinate, we will need to have the X and Y coordinates in parentheses, So (x, y) would be (0, 6). And there you go we have the answer. Good luck!

If f Subscript x​(a,b)equals f Subscript y​(a,b)equals​0, does it follow that f has a local maximum or local minimum at​ (a,b)? Explain. Choose the correct answer below. A. Yes. The point​ (a,b) is a critical point and must be a local maximum or local minimum. B. Yes. The tangent plane to f at​ (a,b) is horizontal. This indicates the presence of a local maximum or a local minimum at​ (a,b). C. No. One​ (or both) of f Subscript x and f Subscript y must also not exist at​ (a,b) to be sure that f has a local maximum or local minimum at​ (a,b). D. No. It follows that​ (a,b) is a critical point of​ f, and​ (a,b) is a candidate for a local maximum or local minimum.




Step-by-step explanation:

The point must be a critical point but it could be a saddle point. If the point is a saddle point it would not be neither a maximum nor a minimum. So it must be critical but it does not follow directly that it has a local maximum or local minimum.

Therefore D. (a,b) would be a candidate, but is not necessarily a maximum or minimum. It could be a saddle.

Solve for x. Round to the nearest tenth. triangle 67, 29, x​


Final answer:

To solve for x in a triangle with side lengths of 67, 29, and x, we can use the Law of Cosines. The value of x is approximately 47.6.


To solve for x in the given triangle with side lengths 67, 29, and x, we can use the Law of Cosines. The Law of Cosines states that for any triangle with side lengths a, b, and c and angle C opposite side c, the following equation holds true: c^2 = a^2 + b^2 - 2ab*cos(C). In this case, we can substitute the given values into the equation and solve for x. Let's calculate it:

x^2 = 67^2 + 29^2 - 2*67*29*cos(C)

x^2 = 4489 + 841 - 3886cos(C)

Solving for x, we find that x is approximately 47.6.
