Answer:33mph
Step-by-step explanation:
the speed decrease by 40%
Therefore, (100-40)%*55miles/h
60%*55
0.6*55
33mph
Answer:
I believe the answer is no
Step-by-step explanation:
Because they are all different numbers
Answer:
-5y+3x
Step-by-step explanation:
-8y-(x-4x) + 3y
= -5y-(x-4x)
= -5y+3x
Answer:
(x - 2)^2 + (y + 5)^2 = 5
Step-by-step explanation:
If the center is at (h, k) : (2, -5), then the general form of the equation of this circle is
(x - 2)^2 + (y + 5)^2 = r^2, and we must find r^2.
We know that (3, -3) is a point on the circle. Substitute 3 for x and -3 for y in the above equation to find r^2:
(3 - 2)^2 + (-3 + 5)^2 = r^2, or
1^2 + 2^2 = r^2
Then r^2 = 5, and the desired equation is
(x - 2)^2 + (y + 5)^2 = 5 or (√5)^2
