Give the equation of a line that is perpendicular to the line y= -4/5x+8

  y = 5/4x

Step-by-step explanation:

The given line is written in slope-intercept form. In this form, the slope is the coefficient of x, -4/5.

The perpendicular line will have a slope that is the opposite reciprocal of this value:

  -1/(-4/5) = 5/4

The simplest such line is the one that goes through the origin:

  y = 5/4x

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
