When a line passes through the two points 
, its slope is given by the formula 
In this question, a line L passes through the points 
So, its slope is given by 
When two lines are perpendicular, then the product of their slopes is -1.
Since, the slope of the line L is 
, so the slope of the line which is perpendicular to the given line L is 
as the product of 
.
Answer:
F = ( 9/5) X c + 32
Step-by-step explanation:
Answer:the tempature will be 22 degrees (i dunno if you measure in Farenheight or celcius so dunno)
Step-by-step explanation: because if the tempature
would rise it would be 22 whatever you measure with
Answer:
35 red marbles
Step-by-step explanation:
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
