If it si proportional
y/x=k or y=kx
if k is same throuout, then it is proportional
find their ratio
so
0/0=undefined, ignore
2/3=k
4/6=2/3=k
6/9=2/3=k
yes, proportional

y=kx
3=2k
1=2/3k
2/3 is answer



proprtional (2nd and 3rd)
graph is proprtional, first table is poroprtional
other ones are not
2nd picture is proportional, 3rd is not


(x,y), y is rise, x is run
unit rate is rise/run=15/6=5/2=2.5
unit rate is 2.5



unit rate is (1/2)/(2/5)=(1/2)(5/2)=5/4=1.25
unit rate is 1.25

The area of a rectangle is 30 + 12x. List at least 3 possibilities for the length and width of the rectangle.
Gala2k [10]

Answer:

Below in bold.

Step-by-step explanation:

Area  = 30 + 12x and area is also = to width * length so we need to look for factors of 30 + 12x.

30 + 12x = 6(5 + 2x)

So  6 and 5 + 2x  is one possible answer.

3 and 10 + 4x is another.

12 and 2.5 + x is another.

If we multiply these pairs together we see that the result is

30 + 12x in each case.

Using algebra, solve the inequality<br> writing your answer in set notation.<br> x²-x&gt; 20
Xelga [282]

Answer:

(-4, 0) U (1, ∞)

Step-by-step explanation:

Set each factor EQUAL to zero to find the zeroes (since it is not actually equal to zero, you will use an open circle when graphing and an open bracket when writing in interval notation).

x = 0           x-1 = 0             x + 4 = 0

                  x = 1                x = -4

Next, choose a value to the far left, between each of the zeroes, and to the far right to evaluate if it makes a true statement when input into the given inequality.

far left (I choose -5): -5(-5 - 1)(-5 + 4) > 0   →  (-)(-)(-) > 0  →   negative > 0  FALSE

- 4 to 0 (I choose -2): -2(-2 - 1)(-2 + 4) > 0   →  (-)(-)(+) > 0  →   positive > 0  TRUE

0 to 1 (I choose 0.5): .5(.5 - 1)(.5 + 4) > 0   →  (+)(-)(+) > 0  →   negative > 0  FALSE

far right (I choose 2): 2(2 - 1)(2 + 4) > 0   →  (+)(+)(+) > 0  →   positive > 0  TRUE
