Equation for the line perpendicular to the line -6x-7y=-6 having the same y-intercept as 8x-5y=10
PilotLPTM [1.2K]
Solving   <span>8x-5y=10   for y helps us to identify the y-intercept:

-5y = -8x + 10.  Dividing both sides by -5, we get (8/5)x -2.  Therefore, y = (8/5)x - 2; the y-intercept is (0,-2).

The equation  </span><span>-6x-7y=-6   can be solved for its slope in the same manner.
7y = -6x + 6;  then y = (-6/7)x + 6/7.  Its slope is -7/6.  A line perpendicular to this line has slope equal to the negative reciprocal of -7/6,  which is 6/7.

So, using the slope-intercept form, y = mx + b becomes y = (6/7)x -2.</span>

At work, Elon takes a break 1/5​​ of each hour he works. He also takes a lunch break for 1/2​​ of an hour each day he works. Elo
Anton [14]

Answer:

h=50\ hours

Step-by-step explanation:

Let

h -----> the number of hours, Elon works during one 5​-day work week

we know that

12\frac{1}{2}\ h=\frac{12*2+1}{2}=\frac{25}{2}\ h

Elon’s break time must be equal to 1/2​​ of an hour multiplied by 5 days plus  1/5​​ multiplied by the total hours h

so

\frac{25}{2}=5(\frac{1}{2})+\frac{1}{5}h

Solve for h

Multiply by 10 both sides to remove the fraction

125=25+2h

2h=125-25

2h=100

h=50\ hours
