Answer:
Step-by-step explanation:
Equation of circle with center (a , b) and radius, r is :
Given : a = 0 , b = - 4
Step 1 : Find the radius.
Given ( 6 , 0 ) lies on the circle. Therefore the distance between the center (0 , - 4) of the circle and ( 6 , 0 ) gives the radius of the circle.
Step 2 : Equation of circle.
Answer:
x = ±
Step-by-step explanation:
Given
2x² - 9 = 11 ( add 9 to both sides )
2x² = 20 ( divide both sides by 2 )
x² = 10 ( take the square root of both sides )
x = ± ← exact solutions
To make it much easier, it should be converted to the slope-intercept form
y = mx + b
To do so, 14x + 34y = 1 turns to:
34y = -14x + 1
Divide both sides by 34:
Simplified:

Here is the graph:
y = mx + b
To do so, 14x + 34y = 1 turns to:
34y = -14x + 1
Divide both sides by 34:
