Please answer this math question Thank u and I will give brianliest !!

B

Step-by-step explanation:

Remember, perpendicular lines have NEGATIVE RECIPROCAL slopes! This means that a line with a slope of a/b's perpendicular line would be -b/a! You can see that in option B, the slopes of the lines are -7 and 1/7, which are negative reciprocals.

Let's take -7 and flip it, then change the sign:

-7 -> -7/1 -> -1/7 -> 1/7

We just confirmed that -7 and 1/7 are negative reciprocals! Therefore, two lines with these slopes are perpendicular.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
