The answer is D. 2
The slope of this line is -1/2
Two lines are perpendicular when multiplying their slopes = -1
The only answer that gives this is D:
(-1/2) * 2 = -1
Answer:
The ratio of tetras to platies is 3:1 or 3/1
Step-by-step explanation:
1, 4, 9, 4, 10, 8, 42
Put this into order.
1, 4, 4, 8, 10, 42
It would most definitely not be the mode, because there is an outlier, and it wouldn't be the median, because once again, there is an outlier.
So, that leaves you with the mean.
The mean would measure this the best because it'll represent it the best. It is also the only one that'll fully make sense.
So, your answer is : The mean.

Situation: Which one of the following is not equal to 100 meters?
We were given 4 different choices with corresponding values, not let's start finding the correct answer.
=> 0.100 kilometers
1 meter = 0.001 km
100 meters = 0.1 km
=> 10 hectometers
1 meter = 0.01 hm
100 meters = 1 hm
=> 10,000 centimeters
1 meter = 100 centimeters
100 meters = 10 000 cm
=> 100,000 millimeters
1 meter = 1000 mm
100 meters = 100 000 mm
<span>thus the not equal answer is hectometer</span>
<span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 to give result as 9x^2 -2x - 5
</span>3x^2 + 4x + 8 + 2x^2 - 6x + 3
= 5x^2 - 2x + 11
so
9x^2 -2x - 5 - (5x^2 - 2x + 11)
= 9x^2 -2x - 5 - 5x^2 + 2x - 11
= 4x^2 -16
answer
expression (4x^2 -16) must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)
