Maybe i have that you wanted
We can represent the situation like that:
Y=-15 and x=-20
Then When y=12 x=?
We make x(The unknown) *-15=12*(-20)
We have an simple équation to solve
Thus x=(12*(-20))/-15
X=16
Answer:
initial cost per issue=$2

Answer:233
Step-by-step explanation:cause i said so
Answer:
(x + 1)² + (y - 3)² = 8
Step-by-step explanation:
radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2
Formula for circle with center (h,k): (x – h)² + (y – k)² = r²
(x + 1)² + (y - 3)² = 8
2x=8
(Divide 2 from both sides)
x=4
