What is the solution to the following system of equations? -5x-4y=-4 25x+20y=20
Tju [1.3M]
Simplify
2nd one divide both sides by 5
5x+4y=4
hmm, seems familliar
times it by -1
-5x-4y=-4
same as other one

they are the same line
therefor the solution set is all the points on the line -5x-4y=-4 or y=(-5/4)x+1


solution set is alll points on y=(-5/4)x+1 or 5x+4y=4

Which is an example x-intercept of the graph of the function y=tan(x-(5pi/6))
emmainna [20.7K]
Answer: x = 5π/6

Explanation:

1) Given function:

y=tan(x- \frac{5 \pi }{6} )

2) x-intercept are the roots of the function, i.e. the solution to y = 0

3) to find when y = 0, you can either solve the equation or look at the graph.

4) Solving the equation you get:

y = 0 ⇒ tan(x - 5π/6) = 0 ⇒ x - 5π/6 = arctan(0)

arctan(0) is the angle whose tangent is zero,so this is 0

⇒ x - 5π/6 = 0 ⇒ x = 5π/6.

Then, one example of an x-intercept is x = 5π/6, which means that when x = 5π/6, the value of the function is 0.

Since, the tangent function is a periodic function, there are infinite x-intecepts, that is why the questions asks for one example and not all the values.

You can verify by replacing the value x = 5π/6 in the given function:

y = tan (5π/6 - 5π/6) = tan(0) = 0.
