Line FG would be tangent because it touches the circle without crossing over, or going through the circle

30 POINTS Which is an x-intercept of the graph of the function y=cot(3x)?

Allisa [31]

Answer:

$x=\frac{\pi}{6}$

Step-by-step explanation:

Choices aren't given, so i will solve this equation and find the first positive x-intercept angle.

First, x-intercept means the x-cutting point of the graph. This occurs when y = 0. So we will solve the equation for x. Shown below:

$y=Cot(3x)\\Cot(3x)=0\\ArcCot(Cot(3x))=ArcCot(0)\\3x=ArcCot(0)$

Inverse Cotangent (ArcCot) of 0 is at $\frac{\pi}{2}$ , so we can now solve for x:

$3x=ArcCot(0)\\3x=\frac{\pi}{2}\\x=\frac{\pi}{6}$

So, the x-intercept is at x = pi/6

The sum of two numbers is 20 and the difference is 12. What are the numbers?

svetlana [45]

Answer:

1) A system of two linear equations to represent this problem

x+y=20 and x-y=12

2) The numbers are x=16 and y=4

Step-by-step explanation:

Let x and y be the two numbers

Given that the sum of the two numbers is 20

That is $x+y=20\hfill (1)$

and the difference is 12

That is $x-y=12\hfill (2)$

1) A system of two linear equations to represent this problem

$x+y=20\hfill (1)$

$x-y=12\hfill (2)$

2). Noe Solve the system to find the 2 numbers:

Adding the equations (1) and (2) we get

$x+y=20$

$x-y=12$

_____________

2x=32

$x=\frac{32}{2}$

Therfore x=16

Now substitute x=16 in equation (1) we get

$16+y=20$

$y=20-16$

Therefore y=4

Therefore the numbers are x=16 and y=4

How to do I do solving systems of equations by elimination

Andre45 [30]

If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16 3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16 -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24. 24-16=8. 3x12=36 36-8=28 And, You're done!
