How to tell if a table represents a linear relationship?
Brums [2.3K]
Either graph the points, or you can divide x by y for each set of points and if your answers are the same, then it is linear. 

Hope it helps!

Please me answer this question
Alex73 [517]

Answer:

x=11, y=13

Step-by-step explanation:

3x-2y=7

3x-2(x+2)=7 .          - x + = -      -2*+2=-4

3x-2x-4=7

1x-4=7

x=7+4

x=11

y=x+2

y=11+2

y=13

Fill in the blanks below.
Crank
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero

the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!

What is the approximate perimeter of a semicircle with a radius of 8 m? Use pi star times = 3.14. Express your final answer to t
irga5000 [103]
The perimeter of a semicircle consists of two parts. (the curve and bottom)
That curve is half the distance around the circle, since it's been split in half.
The distance around a circle, the circumfrence, is equal to 2πr, where r is the radius of that circle. In this case, the circumfrence of the entire circle would be 16π. and so that curve would have a length of just 8π.
Using 3.14 for π, 8π = 8×3.14 = 25.12.
As for the flat part, that is the diameter (distance across) our circle.
The radius is the distance from the center of a circle to its edge, and always has half the length of the diameter. (you can break the diameter down into two radii)
If our radius is 8 meters, our diameter (the flat part of that semicircle) must be 16.
Now we add up the two parts of the perimeter...25.12 + 16 = 41.12.
