You'll want to work with the center-radius form of a circle equation for this. the center formula is <span>(x – h)</span>²<span> + (y – k)</span>²<span> = r</span>², where (h, k) is your center and r is your radius. plug in the information your circle gives you: A(-3, 12), radius = 5
(x + 3)² + (y - 12)² = (5)² ... simplify the right side
(x + 3)² + (y - 12)² = 25 ... from here, you need to foil both of your binomials to convert this to the "general form" that your answer choices are in.
(x + 3)² = (x + 3)(x + 3) = x² + 6x + 9
(y - 12)² = (y - 12)(y - 12) = <span>y² - 24y + 144
</span>
x² + 6x + 9 + y² - 24y + 144 = 25 ... combine like terms
x² + 6x + y² - 24y + 153 = 25 ... subtract 25
x² + 6x + y² - 24y + 128 = 0 is your equation. reorder it so that it's from the highest degree to the lowest: x² + y² + 6x - 24y + 128 = 0 is your result (C).
Answer:The slope on the graph is the price, and it is sloping because the price is cheaper.
Step-by-step explanation:
$10 = 1-6 shirts (amount)
$5 = 7+ shirts (amount)
-8 and 7.
Use the quadratic formula or factor and set equal to 0.
Yes. That statement is true.
For example in : (1/2) divided by (3/4), you would invert 3/4 to make 4/3 and change the divide symbol to the multiply symbol. Becoming:
(1/2) multiplied by (4/3)<em> = </em><em>(1/2) divided by (3/4) = 0.66r</em>
