Two lines are perpendicular, and neither line is horizontal. Which of the following is not necessarily true of the lines?

musickatia [10]

I think the correct answer from the choices listed above is option C. <span>Two lines are perpendicular, and neither line is horizontal so it must be that the slopes of the lines are opposite reciprocals, one slope is positive and the other has a negative slope. Having different slopes so they should intersect the y-axis at different values.</span>

3y - 5x = 9<br> Y= -5/3x-12<br> Are the parallel

bija089 [108]

Answer:

Both lines are not parallel

Step-by-step explanation:

Given as :

Two lines equation are as :

3y - 5x = 9 And y = - $\frac{5}{3}$ x - 12

First line is now written in eq y = mx + c

Or, 3y = 5x + 9

Or, y = $\frac{5}{3}$ x + $\frac{9}{3}$

So, Slop of this line ( m 1 ) = $\frac{5}{3}$

slop of second line ( m 2) is $\frac{- 5}{3}$

∵ The slop of both lines are not equal , so the line are not parallel to each other .

Hence Both lines are not parallel Answer

Determine whether the distribution is a probability distribution. x 0 1 2 3 4 5 P(x) StartFraction 1 Over 25 EndFraction one fi

Citrus2011 [14]

Answer:

D. No comma because the total probability is not equal to 1.

Step-by-step explanation:

Given the distribution:

$\left|\begin{array}{c|cccccc}x&0&1&2&3&4&5\\ P(x)&1/25&1/5&1/2&3/4& 1/50&1/100\end{array}\right|$

The sum of the probabilities

$\sum P(x)=1/25+1/5+1/2+3/4+ 1/50+1/100\\\sum P(x) =1.52 \neq 1$

Therefore, the distribution is not a probability distribution because the total probability is not equal to 1.

The correct option is D.
