1) Just simplify the equation first:
y - 9 = (2/5)(x - 5)
y - 9 = 2x/5 - 2
2) Transfer everything to the left with opposite sign:
-2x/5 + y - 9 + 2 = 0
-2x/5 + y - 7 = 0
3) Get rid of rational numbers by multiplying:
-2x/5 + y - 7 = 0 |*5
-2x + 5y - 35 = 0
That's the answer. Good luck!

5. The measure of an intercepted arc is 86, and the measure of the inscribed angle creating the intercepted arc is 3x +

Nonamiya [84]

Answer:

Th correct option is D. 13

Therefore the value of x is 13.

Step-by-step explanation:

Given:

measure of an intercepted arc = 86°

Center Angle = 86°

measure of the inscribed angle creating the intercepted arc= (3x+4)°

Angle Inscribed in arc = (3x+4)°

To Find:

value of x = ?

Solution:

Inscribed Angle Theorem:

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

$\textrm{Angle Inscribed in arc}=\dfrac{1}{2}\textrm{Center Angle}$

Substituting the values we get

$3x+4=\dfrac{1}{2}86=43\\\\3x=39\\\\x=\dfrac{39}{3}=13\\\\x=13$

Therefore the value of x is 13.
