1. Which inequality is represented by the graph shown?
10
Ays-x+3
By -x +3
Cy<-x + 3
Dy> -x + 3

take your time! :)

D

Step-by-step explanation:

test (0,0):

y > - x + 3

0 > -0 + 3

0 > 3

False

False - means shade away from the (0,0)

True - means shade it where (0,0) is

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

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
