Solve the equations. Show the solution sets on a number line. Check your answers. n/2 − 1/3 −1= 1/6

9/6 - 2/6 - 6/6 = 1/6

Step-by-step explanation:

Change the denominators of all fractions to 6.

n/6 - 2/6 - 6/6 = 1/6

Use inverse operations.

1/6 + 6/6 + 2/6 = 9/6

n = 9

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
