Write an equation of the line that is perpendicular to 3x + 9y = 7 and passes through the point (6, 4).

musickatia [10]

Hi there!

The equation of any line perpendicular to
$ax + by = c$
is
$bx - ay = c$

Therefore, in this situation, the formula of the line would be
$9x - 3y = c$

Given that the line passes through the point (6, 4) we get
$9 \times 6 - 3 \times 4 = c$
$54 - 12 = c$
$c = 44$

Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
$9x - 3y = 44$

Triangle ABC has the following properties: Angle A measures 120°; AB ≅ AC. What is the classification of triangle ABC by angles

Flura [38]

The answer is C <<<=====
It can't be anything else. It is not a right angle. A>90
It can't be acute because one angle is greater than 90.
It can't scalene because at least 2 of the angles (and 2 sides) are equal.

Explain and provide an example of the conditional probability formula, addition rule of probability, and multiplication rule.

Liono4ka [1.6K]

Answer:

P(A ∪ B) = P (A) + P(B) – P(A ∩ B)

Step-by-step explanation:

Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs. For example, given that you drew a red card, what's the probability that it's a four (p(four|red))=2/26=1/13. So out of the 26 red cards (given a red card), there are two fours so 2/26=1/13.
