The median of the trapezoid is the average of the bases. If we draw the trapezoid that is being described in this item, we will deduce that AB and DC are the bases and EF is given to be the median.
For this item,
EF = (AB + CD) / 2
Part A:
EF = (15 + 11) / 2 = 13
Part B:
AB = 2EF - CD
AB = (2)(14) - 10 = 18
Part C:
18 = ((5n - 9) + (2n + 3))/2
18 = (7n - 6) / 2
n = 6
Part D:
2y + 4 = ((5y + 2) + (-3y + 8))/2
y = 1
EF = 2(1) + 4 = 6
AB = (5(1) + 2 = 7
AB = -3(1) + 8 = 5
Step-by-step explanation:
1. let n=2, then, n+2= 2+2=4 so 2^2= 4 and 4^2=16 then 16-4=12 which is an even number
2. let n=4, the. n+3=4+3=7, and 4^2=16 and 7^2=49 then 49-16 =33 which is an odd number

Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Now plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em>, since it is much swifter that way. It does not matter which ordered pair you choose:
7 = 4 + b
If you want it in <em>Standard Form</em>:
y = 4x + 3
- 4x - 4x
_________
_______________________________________________
−5 = 4[−2] + b
−8
If you want it in <em>Standard Form</em>:
y = 4x + 3
- 4x - 4x
_________
** You see? I told you that it did not matter which ordered pair you choose [as long your <em>rate of change</em> is correct] because you will ALWAYS get the exact same result.
