Step-by-step explanation:
second one because
only x+2y=8 passes through the point (2,3)
the proof is 2+2*3=2+6=8
if we replace the given point to the other equations we will take wrong results for example
first equation
x+2y=4. 2+2*3=2+6=8 that is not equal to 4
Answer:
Range: 28
Mean: 12
Step-by-step explanation:
First line the numbers from small to big: 4, 6, 8, 8, 14, 32
Range is biggest minus smallest number
Mean is just the average: all the numbers' sum divided by the number of numbers
Hope this helps! ;)
Let x be the price of one pie.
3x + 1 = x + 9
3x + 1 - 1 = x + 9 - 1
3x - x = x - x + 8
2/2x = 8/2
x = 4
The pies cost $4
