Write the equation of the line perpendicular to y=1/5x-11 passing through the point (0,-8)
Lilit [14]

Step-by-step explanation:

the slope of a line function is always the factor of x.

in our case here : 1/5

it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

in our case that means y increases by 1 for every increase of x by 5.

now, the perpendicular slope simply changes x and y upside-down and flips the sign.

so, here the perpendicular slope is : -5/1 = -5

the line function looks therefore like

y = -5x + b

b is the y-intercept, and we get it by using the coordinates of the point for x and y :

-8 = -5×0 + b = b

so, the full line function is

y = -5x - 8

Ixl p.2 geometry <br> Help me get this to a 70 please
stepladder [879]

Answer:

  3 meters

Step-by-step explanation:

First, you figure out if the triangles are similar. Then, you figure out what the corresponding parts are. Use the relation that corresponding sides are proportional in order to write an equation for q. Solve it.

The angles in ΔDCE are marked the same as the angles in ΔDFB. We have named these triangles in order by the right angle, the angle with 1 arc, and the angle with 2 arcs. The lengths we are given are DC, DF, and DB, and we want to find length DE.

Arranging our equation so the unknown value is in the numerator of a proportion statement, we have ...

  DE/DB = DC/DF

  q/12 = 4/16

  q = 12(4/16)

  q = 3 . . . . meters
