1 answer:
Answer:
x=15 and y= -18
Step-by-step explanation:
Equation 1
Equation 2
From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.
Solving equation 1
Finding 'y' in terms of 'x' Equation 3
Putting above equation in equation 3 in 2
Putting value of 'x' in equation 3 to find the value of 'y'

Answer:
y = (x +2)/(x -3)
Step-by-step explanation:
A rational function is a function (y = ...) that has a definition that is the ratio of two polynomials.
Of the choices listed, the one attached is the rational function.
The complete question is
"A theater production group is making frames to support wall-like props. Three-foot beams form right triangles with 10-foot beams to allow them to stand, as shown in the image.
What is x, the angle at which the diagonal beam meets the 10-foot beam at the top of the frame?
16.7°, 17.5°, 72.5°,73.3°"
The value of angle x would be 16.7 degrees.
<h3>What is the right triangle?</h3>A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
The angle of a right angle is always 90 degrees.
In order to find the value of x, a tan would be used.
This is because we have given the opposite and adjacent sides as 10 ft and 3 ft.
Tan Ф = opposite / adjacent
Tan Ф = (3/10)
= 16.7 degrees
The value of angle x would be 16.7 degrees.
