The same slope would make the equations parallel. Therefore 5/3 would make them parallel.
Answer:
16,425
Step-by-step explanation:
For future references, I'd say use a calculator for multiplication or calculate on a piece of paper. :)
Answer:
Domain: {-2,6,18}
Range: {-1,2,3}
This relation is not a function.
Step-by-step explanation:
The domain is all of the x values given listed in order from least to greatest and not repeating any numbers. The range is the same thing, but with the y values given. This is not a function because multiple ordered pairs have more than one output for the input. Let's take -2 in these ordered pairs. It has two different outputs, 3 and 2. Because of this, it is not a function.
Hope this helps!!
P = 2(L + W)
P = 258
L = 2W - 9
258 = 2(2W - 9 + W)
258 = 2(3W - 9)
258 = 6W - 18
258 + 18 = 6W
276 = 6W
276/6 = W
46 = W <=== here is the width
L = 2W - 9
L = 2(46) - 9
L = 92 - 9
L = 83 <== here is the length
The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.
Area of Square + 4*Area of Triangle = SA
Area of Square:
2^2=4
Area of Triangle:
0.5*2*3=3
SA=4+4*3
SA=16 meters squared
