Answer:

D

Step-by-step explanation:

The answer is point D(-2,1).

1. If the point D was moved down 2 units, then its coordinates became (-2,-1).

2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).

3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).

4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

Can someone PLEASE help me solve these last 2 problems so I can be done with this math class....really stumped on these 2....
dexar [7]
Both distances 3966 and 4746 were done in 6 hours, so the speeds are:
speed against wind = 3966/6=661 km/h (difference of airplane and wind)
speed with wind = 4746/6=791 km/h (sum of airplane and wind)

The speed of airplane is greater than that of the wind, so this is a sum and difference problem.

Greater speed (plane) = (sum+difference)/2=(791+661)/2=726 km/h
Lesser speed (wind) = (sum-difference)/2 = (791-661)/2 = 65 km/h

larisa [96]
Hi there!

The formula for the area of a circle is A = pi x r^2. Using this formula, we can plug in the radius and solve for the area.

WORK:
A = pi x (5)^2
A = pi x 25
A = 25pi cm^2

ANSWER:
B - 25pi cm^2

Hope this helps!! :)

ludmilkaskok [199]
The answer is A. 25
first you subtract 45-34 to find out how much money she makes on one skirt which is $11
then you divide 275÷11 to find out how many she needs to make to break even.
275÷11=25
