The standard equation of a circle with center C(a, b) and radius r is given by:

thus for C(a, b)=C(7, 5) and radius r=4, the equation is given by:

Answer:
8+3 = 11.
4/2 = 1 and 1/2
Hopefully this is the stuff your looking for
Answer:
<1 = 50
<2 = 130
Step-by-step explanation:
<1 and 130 are supplementary angles
<1 + 130 = 180
<1 =180-130
<1 = 50
130 and <2 are corresponding angles and corresponding angles are equal when the lines are parallel
<2 = 130
Answer:
Here we need to solve:

The sum of the fractions is equal to the quotient between the fractions.
Notice that the two values:
y = 3
y = -3
make the denominator equal to zero, so those values are restricted.
We can simplify the right side to get:

Now we can multiply both sides by (y - 3)

Now we can multiply both sides by (y + 3)


First, let's see the determinant of that quadratic equation:

We can see that it is negative, thus, there are no real solutions of the equation.
Thus, there is no value of y such that the origina equation is true,
