Answer:

4/45

Step-by-step explanation:

First find all the pairs that make 9 that are two digit:

1+8

2+7

3+6

4+5

5+4

3+6

2+7

1+8

That's 8 pairs, and as there are 90 two digit numbers, 8/90 is the answer. but if you want to simplify, the answer is 4/45

Which lines are perpendicular to the line y - 1 = 1/3 (x+2)? Check all that apply.
ioda

Answer: Options 1, 3, 5

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals, so since the slope of the given line is 1/3, we need to find lines with a slope of -3.

  • Option 1 has a slope of -3.
  • Option 2 has a slope of 3.
  • Option 3 has a slope of -3.
  • Option 4 has a slope of 1/3.
  • If we subtract 3x from both sides, we get y=-3x+7, so option 5 has a slope of -3.
