Well standard form is Ax+By=C, so just move the -7x to the front so -7x+47=16
190-15=x
I believe?
I THINK THIS IS THE ANSWER
The equation of a direct variation is of the form
But the given function can be rewritten as
This is a partial variation,
is the constant of variation and
is the fixed constant.
The secant of the angle through a point (-5, 3) is -13/5
<h3>Equation of a circle</h3>
The equation of a circle with center (0,0) is given by
x² + y² = r² where r = radius of circle
Now, comparing this to the equation of the given circle x² + y² = 169,
⇒ r² = 169
r = √169
r = 13
<h3>Secant of angle </h3>
The secant of the angle through a point (x, y) is secФ = r/x where
- r = radius of circle and
- x = x-coordinate of point
Now for the point A(-5,12), x = -5.
Since r = 13
secФ = r/x
= 13/-5
= -13/5
So, The secant of the angle through a point (-5, 3) is -13/5
