First we need to find the slope of line k. Using the slope formula, we fill in accordingly:

. The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
Answer:
B
Step-by-step explanation:
Out of the 4 options, we only need 1. Therefore, the probability is 
Answer:
Step 1
Step-by-step explanation:
The first step of the problem instantly shows a mistake. The gloves are 4% off of $30, not $4 off. Instead, the first step should be $30 - $1.2
7/10 because you add seven and three which equals ten, and seven of them are dimes.
Answer: x=-1/2
Step-by-step explanation:
8x=-4
divide by 8 on both sides
x=-1/2
