2
y
0
1
1 10
6 14
10 21
20 28
O2=0 to = 1
OI=1 to x = 6
Submit Answer
2=6 to = 10
O2 = 10 to 2 = 20

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

7

step-by-step explanation:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
