Answer:

The value of x would be -3.

Step-by-step explanation:

Consider the complete question is,

'Which represents all the values of x that make the rational expression \frac{-6x + 42}{3x + 9} undefined?'

Since, the rational expression is defined for all real values except those for which denominator is equal to zero,

If 3x + 9 = 0,

3x = -9

\implies x =-\frac{9}{3}=-3

Hence the values of x that make the rational expression undefined would be -3.

What is 1/3 + 5/6 Help
gulaghasi [49]

<em><u>7/6 is the right answer.</u></em> First you had to add by the fractions. And it gave us, \frac{2}{6}+ \frac{5}{6}. Since the denominators are equal, combine the fractions. And it gave us, \frac{2+5}{6}. Finally, you had to add by the numbers, and it gave us the answer is 2+5=7, or 7/6 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

The sail of a boat is in the shape of a right triangle, as shown below:
dolphi86 [110]
Answer: Choice C
7 divided by cosec 50 degrees

=====================================

Explanation:

Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)

-----------------

Let the horizontal leg be x

This leg is opposite the angle 50 degrees. The hypotenuse is 7

Opposite = x
Hypotenuse = 7

We'll either use the sine rule or the cosecant (csc) rule
sine = opposite/hypotenuse
cosecant = hypotenuse/opposite

Since "sine" is nowhere to be found in the answer choices, we'll use the cosecant rule

-----------

cosecant = hypotenuse/opposite
csc(angle) = hypotenuse/opposite
csc(50) = 7/x
x*csc(50) = 7
x = 7/csc(50)

This is why the answer is choice C
