Answer:

<h3>             C.    y + 7 = -7(x - 3)</h3>

Step-by-step explanation:

The equation of a line is:

                          y - y₀ = m(x - x₀)

where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through

The product of slopes of two perpendicular lines is  -1

so if given lines slope is ¹/₇ them:

     ¹/₇·m = -1

        m = -7

(3, -7)     ⇒    x₀ = 3,  y₀ = -7

Therefore:

               y - (-7) = -7(x - 3)

                <u> </u><u>y + 7 = -7(x - 3) </u>

Twenty more than four times a number is equal to the difference between 139 and three times the number. Find the number.
Lady_Fox [76]

Answer:

x = 17

Step-by-step explanation:

First, let's turn this into an equation:

twenty more ( +20 ) than four times a number ( 4x ) is equal ( = ) to the difference ( - ) between 139 and 3 times the number ( 3x ).

4x + 20 = 139 - 3x

Now let's solve:

Subtract 20 from each side:

4x = 119 - 3x

Add 3x to each side:

7x = 119

Divide each side by 7:

x = 17
