3. Solve the system using elimination.
[-x+ y = 9
X-y=-9
A:infinite solutions
b:no solution
c:(2,-1)
d:(-2,1)

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

3 qrs + 3/2 xy hope this : /

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
