Answer:
the difference of -9 - 17 = -26
Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
Step-by-step explanation:
Step-by-step explanation:
A. D(t) = -25t + 160
this is the correct answer because if you substitute 3 you get 85
One way to solve this is by changing the mixed numbers to improper functions.
3 1/3 = 10/3
2 2/5 = 12/5
The next step I would take is to find a common denominator.
10/3 = 50/15
12/5 = 36/15
Now we can solve the original equation:
50/15 - 36/15 = 14/15
Since 14/15 is already simplified this is your final answer.
