**Answer:**

The coordinates of the center of this circle is (-1, -3).

**Step-by-step explanation:**

As we know that and are points lying on circle T, the center is the midpoint of the segment AB, whose location can be obtained from Midpoint formula:

The coordinates of the center of this circle is (-1, -3).

**Answer:**

the equation is: f(x)= 1/2x + 1

**Step-by-step explanation:**

the 1/2 comes from the slope, while the 1 comes from the y intercept

**Answer:**

52 cards

**Step-by-step explanation:**

call the amount he started with " x "

then he bought 8 cards

so the new equation is

x+8

then he lost half of his cards

so now the equation is

(x + 8 )/2

that amount to 30 cards as per what is given in the problem

so now the equation is

( x + 8 )/2 = 30

solve using inverse operations and simplifying

( x + 8 )/2 = 30

*2 *2

x + 8 = 60

-8 -8

x = 52

Yes is it equal to 1/3 because 4 goes into 12 three times. See what i'm saying?

**Answer:**

y = -6

**Step-by-step explanation:**

y = -4x - 2

Replace x with 1:

y = -4(1) - 2

Multiply -4 and 1:

y = -4 - 2

Subtract -4 and -2:

y = -6
