Answer:
1,500 points per minute
Step-by-step explanation:
You can tell it's 1500 points per minute because the lines meet up at (2,3) meaning that 3/2 = 1500, to double check you could do 9/6 where the points also meet up at the exit of the graph which is ALSO 1.5 meaning 1,500 points per minute
Remark
All vertical lines are of the form x = a. The y value only places where the point is on the grid.
For this particular question the x value of the point is where the vertical line is. At x = -2 draw a vertical line. The graph shows what this looks like.
The graph (x = - 2) is in red.
The point (-2,10) is green.
Answer:
(-2,-2)
Step-by-step explanation:
The closet point on a line to any given point is the point where a perpendicular line intersects them both. The perpendicular line to y=-x-4 that intersects (4,4) is y=x. If you graph them both, you will find that they intersect at (-2,-2).
Answer:
length of rectangle = 32.25 cm
Width of rectangle = 10.75 cm
Step-by-step explanation:
Let the length of rectangle be x.
And width of rectangle be y.
According to the problem,
x = 3y {Since the length of a rectangle is equal to triple the width}
Also,
Perimeter of rectangle = 86
or 2 (x + y) = 86
Plug x =3y in the above equation
We get, 2(3y + y) = 86
2 * 4y = 86
4y = 43
y = 43/4 = 10.75
So, length of rectangle = 3 * 10.75 = 32.25cm
Width of rectangle = 10.75cm
