-38(-3) = 114

-72/(-12) = 6

-9 x 23 = -207

-150/5 = -30

564 / -4 = -141

<h3><u>Solution:</u></h3>

Given that, we have to find each product or quotient

<em><u>-38(-3)</u></em>

It is a product, so we have to find product value

-38(-3)=38 \times 3=114

<em><u>-72 / (-12)</u></em>

It is division, so we have to find the quotient

\frac{-72}{-12}=\frac{72}{12}=6

<em><u>-9 x 23</u></em>

It is a product, so we have to find product value

-9 \times 23=-207

<em><u>- 150 / 5</u></em>

It is division, so we have to find quotient

\frac{-150}{5}=-30

<em><u>564 / -4</u></em>

It is division, so we have to find the quotient

\frac{564}{-4}=-141

Determine the equation of the line perpendicular to the line y = -8 through the point (-4,-2).
ludmilkaskok [199]

The line y = -8 is horizontal

The line perpendicular to the line y = -8 is vertical

The equation of the line perpendicular to the line y = -8 through

the point (-4 , -2) is x = -4

Step-by-step explanation:

Let us revise some notes about the vertical and horizontal lines

  • The equation of a horizontal line passes through point (a , b) is y = b, because the y-coordinates of all points on the line are equal
  • The equation of a vertical line passes through point (a , b) is x = a, because the x-coordinates of all points on the line are equal
  • The horizontal line and the vertical line are perpendicular to each other

We need to find the equation of the line perpendicular to the line y = -8 through the point (-4 , -2)

∵ The equation of the given line is y = -8

∴ The given line is a horizontal line

The line y = -8 is horizontal

∵ The line y = -8 is a horizontal

∴ The line perpendicular to it must be vertical

The line perpendicular to the line y = -8 is vertical

∵ The equation of a vertical line is x = a, where a is the x-coordinate

   of a point lies on the line

∵ The line perpendicular to the line y = -8 through the point (-4 , -2)

∴ a = -4

∴ The equation of the perpendicular line is x = -4

The equation of the line perpendicular to the line y = -8 through

the point (-4 , -2) is x = -4

Please hurry I will mark you brainliest <br><br> What is the slope of this?
Nonamiya [84]

Answer:

-1/4

Step-by-step explanation:

Pick two points on the line

(-4,3) and (4,1)

Using the slope formula

m = (y2-y1)/(x2-x1)

    = ( 1-3)/(4 - -4)

    = (1-3)/(4+4)

   = -2/8

   = -1/4
