Subtraction is part of the early arithmetic. Subtraction pertains to the part of math that involves reducing a sum to a smaller amount. Take this as an example, 7-4=3.

Which of the following pairs of lines are perpendicular? Select all that apply.
nataly862011 [7]

Answer:

y  = \frac{4}{5} x - 8

y = -\frac{5x}{4} + 3

y  = \frac{2}{3} x - 8

y = \frac{-3}{2}x - 8

Step-by-step explanation:

To know the pairs that are perpendicular lines, we need to understand what makes a line perpendicular to another.

Perpendicular lines generally have slopes;

      m and -\frac{1}{m}

So, any of the pairs with a negative inverse value of slope will be perpendicular.

     y  = \frac{4}{5} x - 8         slope = \frac{4}{5}

     y = -\frac{5x}{4} + 3       slope  = -\frac{5}{4}

We see they are negative inverses

     y  = \frac{2}{3} x - 8         slope  = \frac{2}{3}

     y = \frac{-3}{2}x - 8        slope = -\frac{3}{2}

These are also negative inverses.

Write an equation of a line passing through point p(4, 0) that is parallel to the line -x+2y=12​
dedylja [7]

Answer:

y  = \frac{1}{2}x - 2

Step-by-step explanation:

Given parameters:

    Coordinates = p(4,0)

  Equation of the line   -x+2y=12​

Solution:

A line parallel to the given line will have the same slope as it is;

     -x+2y=12​

          2y = x + 12

            y = \frac{1}{2}x + \frac{12}{2}

 Since this conforms to y = mx + c where;

    x and y are the coordinates

    m is the slope

   c is the intercept

Our slope is \frac{1}{2}

The equation of the line is

      y = mx + c

let us find c;

     c  = y - mx

     c = 0 - (\frac{1}{2} x 4)

     c = -2

Now the equation of the line parallel to the line given is;

     y  = \frac{1}{2}x - 2

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.<br><br> Work out Pip's share.
oksano4ka [1.4K]
<h3>Answer:   $628 </h3>

==========================================================

Work Shown:

x = Ali's share

4x = Pip's share, because it is four times bigger due to the ratio 4:1

x+4x = 5x = total amount of money = 785

5x = 785

x = 785/5

x = 157 dollars is Ali's share

4x = 4*157 = 628 dollars is Pip's share

Note that 157+628 = 785 to help confirm the answer.
