Answer : B x 1 2 3 4 y 3.2 6.4 9.6 12.8
WE analyze the first option A
x -- y -- Difference
8 -- 20
9 -- 22.5 -- 2.5
10 -- 25 -- 2.5
11 -- 27.5 -- 2.5
From the first function we can see there is a constant difference of 2.5.
We analyze the second option B
x -- y -- Difference
1 -- 3.2
2 -- 6.4 -- 3.2
3 -- 9.6 -- 3.2
48 -- 12.8 -- 3.2
From the second function we can see there is a constant difference of 3.2
3.2 is the greatest
So second function B has the greatest constant of variation.
Answer:
1) y > x
2) x > 5 > y
3) x ≤ 4 ( or 4 ≥ x )
4) x = y
Step-by-step explanation:
1) 1. y is greater than x
2. so y > x
2) 1. 5 is less than x and more than y
2. we can write this like x > 5 > y
3. you can just squish them together as a shortcut usually: x > 5 and 5 > y --> x > 5 > y
3) 1. x is for at most, we can say this as x is less than or equal to 4
2. this is written as x ≤ 4 or 4 ≥ x
4) 1. x - y = 0 so x and y must be the same value
2. therefore x = y
4)
ordered pairs : (-5,4)(-3,2)(2,6)(-3,-5) it is not a function because it repeats x’s
5)
ordered pairs : (4,5)(2,5)(1,-3)(-2,-2) it is a function because it is NOT repeating x’s
6)
(2,6)(6,8)(6,10)(8,12) it is not a function because it repeats x’s
Yeah I’m sorry I don’t know the answer
1. Pick two points on the line and determine their coordinates.
2. Determine the difference in y-coordinates of these two points (rise).
3. Determine the difference in x-coordinates for these two points (run).
4. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
