Answer:
Step-by-step explanation:
The equation of a circle with center (h,k) and radius r is given by the formula;
Given (h,k)=(0,0) and r=4, we substitute the values to obtain;
The required equation is
3x^2 + 11x - 4 = 0
x^2 + (11/3)x = 4/3
(x+11/6)^2 = 169/36
Answer is B.
Answer:
-2.46, -10/4, 14/5, 2.5.
Step-by-step explanation:
Okay, I will give you the building blocks for solving this equation.
Now something you will need to remember is that a triangle will always add up to 180 degrees.
We can use y as that one unknown side in the triangle.
Knowing this, we can say (9x+16) + (6x+15) + y = 180
Then we can combine like terms like so : 15x+31+y = 180
There are two variables though. So we need more information.
Well, turns out we have the exterior angle of a straight line and the angle measures of a straight line must equal 180. We can now use (19x+3) + y = 180.
With both of these equations, you can now solve and find both of the angles
The answers are in the picture below.
