This is perhaps the most odd math question I have ever come across. Anyhow -


#1 - Positive, because smoking increases the chance of having lung cancer. (though technically there is not a linear relationship between the two as people do in fact receive lung cancer even when having not smoked)


#2 - No relationship. (Though one could argue a student may text more when given more free time as a consequence of having spent less time at school, but this is wholly subjective and unable to be substantiated by logic.)


#3 - Negative, due to the mass of the tootsie pop decreasing with each lick.


Of course, I am assuming when you say "positive" and "negative" you are speaking in terms of numbers or addition and subtraction rather than "positive" or "negative" socially.

Answer:

Smoking and cases of lung cancer is positive.

Amount of time spent at school each day and the number of texts sent per day is not causal

The number of licks taken and the size of the Tootsie Pop is negative.

Step-by-step explanation:

1Because as one keeps on smoking the risk of lung cancer increases.

2. Time spent at school has nothing to do with number of texts, so it's not causal.

3. The more one licks the Tootsie Pop the more it decreases.

2x - 3y = 12<br> x = 4y + 1
aliya0001 [1]

Answer:

x = 9, y = 2 is the solution of the given system.

Step-by-step explanation:

Here, the given set of equation is :

2 x - 3 y = 12

x = 4 y + 1

Now, from equation (2) we see that x = 4 y + 1.

Substitute the value of y from (2) in the first equation. we get:

2 x - 3 y = 12  ⇒ 2 (4 y + 1) - 3 y = 12

or, 8 y + 2 - 3 y = 12

or, 5 y = 12- 2  = 10

or, y = 10/ 5 = 2

or, y = 2

Now, x = 4 y + 1   ⇒ x  =  4(2)  + 1 = 8 + 1 = 9, or x = 9

Hence, x = 9, y = 2 is the solution of the given system.

Two lines intersect, and you know the measure of one angle. How can you determine the measures of the other three angles
alukav5142 [94]

Answer:

Opposite angles are the same measure.

Angles around a point = 360°

When you add all the angles, you get 360.

Angle a and b would measure the same and so would angle d and c. So you double the measure for one of those angles and subtract it from 360.

Then, you half that value( divide by 2) and this is to find the measure of the other angle
