Which of the following would be an acceptable first step in simplifying the expression tanx/1+ secx
djverab [1.8K]

The acceptable first step in simplifying the expression \mathbf{\frac{tan\ x}{1 + sec\ x}} is (a) \mathbf{\frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}

The expression is given as:

\mathbf{\frac{tan\ x}{1 + sec\ x}}

To change the form of the expression, we simply perform several arithmetic operations on it.

Start by multiplying the expression by 1/1

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac 11}

Express 1 /1 as (1 - sec x)/(1 - sec x)

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac{1 - sec\ x}{1 - sec\ x}}

Rewrite the above expression as follows:

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}

Hence, the acceptable first step is (a)

This morning Allen had 2 more action figures than Barbara, and Barbara had 8 more action figures than Charlie. Allen have some o
Zina [86]

The value of N is 5.

Let x represent the number of action figures Allen has.

Let y represent the number of action figures Barbara has.

Let z represent the number of action figures Charlie has.

<h3 /><h3>Generating the equations</h3>

Given that this morning Allen had 2 more action figures than Barbara, we have that x = y + 2 (1)

Also, Barbara had 8 more action figures than Charlie, we have that y = z + 8 (2)

Now, Allen have some of his action figures to Charlie, and now both Allen and Charlie have the same number of action figures.

Let p be the number of action figures Allen gave to charlie. So, Allen now has x - p action figures and Charlie now has z + p

Since now, both Allen and Charlie have the same number of action figures, we have that

x - p = z + p (3)

Barbara now has N more action figures than Charlie does.

So, y + N = z + p + 8 (4)

<h2 /><h2>Solving the equations</h2>

Substituting (2) into (1), we have

x = y + 2

= z + 8 + 2

= z + 10

x = z + 10 (5)

<h3>The value of p</h3>

Substituting (5) into (3), we have

x - p = z + p

z + 10 - p = z + p

10 - p = p

10 = 2p

p = 10/2

p = 5

<h3 /><h3>The value of N</h3>

Substituting (2) into (4), we have

y + N = z + p + 8

z + 8 + N = z + p + 8

N = p

Since p = 5, N = 5

So, the value of N is 5.
