Points h and f lie on circle c. circle c is shown. line segments e c, f c, and d c are radii. tangents e g and d g intersect at point d outside of the circle. a line is drawn to connect points f and g. the length of g e is 12 and the length of e c is 9. angles e and d are right angles. what is the length of line segment gh?

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

your answer is b.

x = 33.9

y = 65.6
