Answer:
see the attached for the table and rules
Step-by-step explanation:
a) A graph of the given points shows they lie on the same line, one with a slope of 3 and a y-intercept of 2. Thus the rule is ...
y = 3x +2
see the attachment for table values
__
b) The ratios of given points are all the same: y/x = 5/2, so that is the constant of proportionality:
y = (5/2)x
see the attachment for table values
2x2 + 5x + 3
= (2x +
<span>)(x + 1)
and the answer is 3</span>
The first one
the first 2 numbers gives a power of 1 then the second gives you 1-4.
1+1-4 is -2 so its the first one
The median is the middle number, the range is the difference between the lowest and highest values(subtract the lowest number from the highest number) and the mode is the number that appears most often in a set of numbers
Hope this helps
