Answer:
The center of this circle is found at (4, -2) and the radius is 6.
Step-by-step explanation:
The equation for a circle in standard for is ( x – h)² + ( y - k)² = r². In this equation, (h, k) is the center of the circle and r is the radius.
From the given equation, ( x – 4)² + ( y + 2)² = 36, h is already subtracted from x, so h = 4, but the k is not subtracted, so (y + 2) = [y - (-2)], and we see that k is -2. Therefore, the center of the circle is (4, -2) and 36 = r². By taking the square root of 36, we find that r = 6.
The center of this circle is found at (4, -2) and the radius is 6.
The answer with Be B good choice
Answer:
Step-by-step explanation:
Using the information provided we can create the following two equations each of which calculates the total number of minutes that the whale (w) or the platypus (p) can stay underwater. In order to solve each, you would need the value of at least 1 of the mammals.
w = 7 * (p+x)
p = (w / 7) - x
The w in these equations represents the number of minutes the whale can stay underwater while the p represents the number of minutes that the platypus can stay underwater.
Answer:
x = 8
Step-by-step explanation:
Let's solve your equation step-by-step.
5x−6=3x+10
Step 1: Subtract 3x from both sides.
5x−6−3x=3x+10−3x
2x−6=10
Step 2: Add 6 to both sides.
2x−6+6=10+6
2x=16
Step 3: Divide both sides by 2.
2x
