I need help with this question. I think I already chose the correct answer but I'm not sure.
iris [78.8K]

Answer:

B. cosθ ≠ 0

Step-by-step explanation:

As we notice, tanθ is a fraction. Fractions are undefined when the denominator is equal to or approaching 0 because one cannot divide by zero. Thus, the denominator in this case is cosθ, and therefore it cannot equal zero for the equation to be true.

Solve for x: 3(x + 1) = −2(x − 1) + 6
In-s [12.5K]

Answer:

<h2>x = 1</h2>

Step-by-step explanation:

3(x + 1) = −2(x − 1) + 6

Expand the terms in the bracket and simplify

That's

3x + 3 =  - 2x + 2 + 6 \\ 3x + 3 =  - 2x + 8

<u>Add 2x to both sides of the equation</u>

3x + 2x  + 3 = 2x  - 2x + 8 \\ 5x + 3 = 8

<u>Subtract 3 from both sides of the equation</u>

5x + 3 - 3 = 8 - 3 \\ 5x = 5

<u>Divide both sides by 5</u>

\frac{5x}{5}  =  \frac{5}{5}  \\

We have the final answer as

<h3>x = 1</h3>

Hope this helps you

PLZ HELP ASAP SOLVE SIMMILAR TRIANGLES LAST ONE
zvonat [6]
For this case by similarity of triangles we can use the following relationship:
 (x) / (9) = (5) / (15)
 We clear the value of x:
 x = ((5) / (15)) * (9)
 Rewriting:
 x = (1/3) * (9)
 x = 3
 Answer:
 
The value of x for this case is:
 
x = 3

PLEASE help me !!!! i dont know the exponent
Serggg [28]

Answer:

24\sqrt[3]{x^{7}}

Step-by-step explanation:

The exponent rule that applies to products like this is ...

... (a^b)(a^c) = a^(b+c)

In your problem, this is

... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)

This fractional exponent translates to the root of a power:

... = (x^7)^(1/3)

In typeset form, it is ...

\sqrt[3]{x^{7}}

You have already figured correctly that the coefficient is 3·8 = 24.
