The equation for line g is given by 5y=2x-20. suppose line g is parallel to like r and line e is perpendicular to line g. point (10,-8) lies on both line r and line e. write an equation for line e

5x + 2y = 34

Step-by-step explanation:

The desired line is perpendicular to 5y = 2x -20 and goes trhough point (10, -8).

General Approach

You can write the equation of a perpendicular line through (h, k) by ...

Then, you can put the equation in the form you desire.

This Problem

... 2(y+8) = -5(x-10) . . . . . coefficients swapped, negated; replacements made

... 2y + 16 = -5x +50 . . . . eliminate parentheses

... 5x +2y + 16 = 50 . . . . .add 5x

... 5x + 2y = 34 . . . . . . . .  subtract 16. This the equation in standard form.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
