Answer:
D
Step-by-step explanation:
Answer:
(x + 1)^2 + (y - 2)^2 = 3^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is
(x + 1)^2 + (y - 2)^2 = 3^2 = 9.
First, it would help to simplify each side more:
Left side: 36 + 3(4x - 9) = 36 + 12x - 27 = 12x + 9
Right side: c(2x + 1) + 25 = 2cx + c + 25
Write the simplified equation:
12x + 9 = 2cx + c + 25
Usually when there is no solution, the coefficients of the variable on both sides are the same, so we can make the coefficient if x on the right side into 12:
2cx >>> 12x
Then, c must equal 6 to make this true.
The answer is choice (C).
Answer:
x^2-6x+9
Step-by-step explanation:
(x-3)^2
(x-3)(x-3)
x^2-3x-3x+9
x^2-6x+9
Answer: $13.70
Step-by-step explanation:
.10* 17= 1.7, because $.10 is charged for everyday the book is late and the books were 17 days late.
1.7* 4= 6.8, because there were four books that were 17 days late.
.10* 23= 2.3, because $.10 is charged for everyday the book is late and the books were 23 days late.
2.3* 3= 6.9, because there were three books that were 23 days late.
6.8+6.9= 13.70 is the amount of money Sydney had to pay the library for her late books.
