Answer:

9x – 5 y = -12

any point along this line

Step-by-step explanation:

9x – 5 y = -12

-9x + 5y = 12

Add the two equations

9x – 5 y = -12

-9x + 5y = 12

-------------------------

0x   + 0y   = 0

There are infinite solutions since the y are the same line

You roll a number cube one time.<br> What is the probability of not rolling a 8 or a 10?
liq [111]

Answer: 80% or 4/5

Step-by-step explanation:

so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.

10 numbers

10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)

so 8/10 or 80%

reduced fraction: 4/5

percentage: 80%

fraction: 8/10

*will edit if needed

saw5 [17]

Answer:

Angle A: 72°

Angle B: 108°

Step-by-step explanation:

Opposite angles are equal

Adjacent angles add up to 180

5y - 3 = 3y + 27

2y = 30

y = 15

Angle A:

5(15) - 3 = 72°

Angle B:

180 - 72 = 108°
