To translate a figure on a coordinate plane, it is basically moving it so many units horizontally or so many units vertical by counting the amount of units you have on weather it is positive or negative. If it looks like (7,-2) The 7 is your x value, so you would move it 7 to the right and place your first point there and do that to the rest of your points. Now the -2 is your y value, so you would move your first point down 2 and do that to the rest of your points!
Let x and y be the speeds of the two points. The circle is of length 120m that is Circumference of circle is 120m.When the points are moving in opposite directions, they meet in every 15 seconds.That is the points cover 120m in 15 seconds.As they are moving in opposite directions, so the relative speed will be equal to the sum of speeds of both points.Speed= Distance ÷Time = 120÷15=8m per seconds.
x+y=8
When going in the same direction, one point catches up to the second every 60 seconds.Speed= 120÷60=2 m per seconds
x-y=2.
Solving the two equations by elimination method:
x+y=8.
x-y=2
Adding the equations:
2x=10 ,x=5m / sec.
x+y=8
5+y=8
y=3m/sec.
Thus, the speed of the two points is 5 m/s and 3 m/s.
Answer:
y = 2x -1
Step-by-step explanation:
y = mx + b
y = 2x + b
7 = 2(4) + b
7 = 8 + b
-8 -8
-1 = b
A would be your answer
Hope this helps !!
The sum of the angles equals 540
There are 3 angles that measure (x - 30) and 2 angles that measure (x)
3(x - 30) + 2(x) = 540
3x - 90 + 2x = 540
5x - 90 = 540
5x = 630
x = 126
x - 30 = 126 - 30 = 96
Answer: x = 126, x-30 = 96
