$\dfrac{x^2 + 5x + 6}{x + 3} =$

Factor the numerator:

$= \dfrac{(x + 3)(x + 2)}{x + 3}$

$= x + 2$

Answer:

b, c

Step-by-step explanation:

Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)

Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)

Andrei [34K]

Answer:

Step-by-step explanation:A.

Slope =

Step-by-step explanation:

We are given the equation of the line as .

A. The co-ordinate is given by

Substituting the value , we get,

implies implies i.e. 3x = -1 i.e.

Thus, the co-ordinate is .

B. The co-ordinate is given by

Substituting the value , we get,

implies implies i.e. 9y = 0 i.e. y= 0

Thus, the co-ordinate is .

Since, the slope of a line is given by .

We get,

Slope = .

i.e. Slope = .

Hence, the slope of the line is .

1.) The commuter trains on the Red Line for the Regional Transit Authority (RTA) in Cleveland, OH, have a waiting time during pe

alisha [4.7K]

Answer:

a) For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

b) $f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

Step-by-step explanation:

Part a

For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

Part b

For this case the density function would be given by:

$f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

And $f(x)= 0$ for other case.
