Answer:

cot²x

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1, then

1 - sin²x = cos²x

1 - cos²x = sin²x

Thus

\frac{1-sin^2x}{1-cos^2x} = \frac{cos^2x}{sin^2x} = cot²x

What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1
Natali5045456 [20]

After putting the value of y from the second equation to the first equation, the resultant equation is x=5.

GIven:

The equations are:

3x + y = 1\\&#10;y = 6 - 4x

It is required to put the value of y from second equation to the first equation.

<h3>How to solve equations?</h3>

The value of y from the second equation is,

&#10;y = 6 - 4x

Now, put this value of y in the first equation as,

3x + y = 1\\&#10;3x+(6 - 4x)=1\\&#10;3x+6-4x=1\\&#10;-x=-5\\&#10;x=5

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is x=5.

Look at the figure find the value of x for which l || m
Orlov [11]

Answer:

x=5

Step-by-step explanation:


19x and its vertical angle are equal.  Lets call that angle y

<y and 17x are same side interior angles.  Same side interior angles add to 180 if the lines are parallel.  Since l is parallel to m.

<y + 17x=180

We know that y and 19x are equal since they are vertical angles, so we can substitute this in.

19x+ 17x = 180

Combine like terms.

36x = 180

Divide each side by 36

36x/36 = 180/36

x = 5

The price of a visit to the dentist is $50 . If the dentist fills any cavities, an additional charge of, 100$ per cavity gets ad
frozen [14]
The cost of the visit to the dentist can be expressed as the cost equals 100x+50.

The initial cost of the appointment would be $50; no matter how many cavities one has, they would still have to pay $50.

The cost of each cavity is represented as 100x, because each cavity costs $100. x represents the number of cavities, as we do not know how many cavities there are.
