Answer:  The correct option is (A) Add the equations to eliminate p.

Step-by-step explanation:  Given that an unknown number w is 30 more than an unknown number p. The number w is also p less than 5. The equations to find p and w are shown below:

w=p+30~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\w=-p+5~~~~~~~~~~~~~~~~~~~~~~~(ii)

We are to select the correct step to find p and w.

Since the co-efficient of p is 1 and -1 in equations (i) and (ii) respectively, so adding both the equations will eliminate p, and we will get the value of w.

Then, substituting the value of w in any one of the equations will give us the value of p.

So, the system of equations is solved as follows :

Adding equations (i) and (ii), we get

w+w=30+5\\\\\Rightarrow 2w=35\\\\\Rightarrow w=17.5.

Substituting the value of w in equation (i), we get

p=w-30=17.5-30=-12.5.

Thus, the correct step is the add the equations to eliminate p.

Option (A) is CORRECT.

The given equations are

w = p+30 \\ w = -p+5

TO solve for p and w, we can use elimination method. And the first step is to eliminate p by adding both equations .

So out of the given options, correct option is the first option .

Write the equation of line in slope-intercept form :Line parallel to the y-axis that passes through the point (77,88) PLZ HELP
sammy [17]

A line parallel to the y-axis that passes through (77,88) is x = 77.  There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.

I am trying to figure this question: <br><br> 1 + tan^2A = Sec^2A
chubhunter [2.5K]

Answer:

see explanation

Step-by-step explanation:

Using the Pythagorean identity

cos²A + sin²A = 1 ( divide terms by cos²A )

\frac{cos^2A}{cos^2A} + \frac{sin^2A}{cos^2A} = \frac{1}{cos^2A} , that is

1 + tan²A = sec²A ← as required
