|r|=-2 solve the equation and graph the solution if possible

1 answer:

6 0

That bracket symbol, with an r in it, means "the absolute value of r".
So r's absolute value is -2 meaning r is two units from zero
r= 2

ahrayia [7]

<h3>Answer:</h3><h3>All of them meet at the gym again after 48 days and it will be tuesday</h3>

Step-by-step explanation:

Lily goes to gym once every 8 days.

Such that she will visit on 8, 16 , 24, 32 , 40, 48th days

Ann goes once every 12 days

Such that she will visit on 12, 24, 36, 48, 60th days ....

Taylor comes once every 16 days

Such that she will visit on 16, 32, 48, 64th days....

Comparing the common days on which they will visit again after wednesday,

it will be after 48 days, (i.e) after 6 weeks and 5 days, it will be tuesday

Write the equations for the line parallel and the line perpendicular to the given line passing through the given point.

pashok25 [27]

Answer:

10. y=2x+1 y = -1/2x +1

11. y=-1/3x +6 y = 3x -4

12. y=-5x-18 y=1/5x + 14/5

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope, we use the slope from the equations for parallel lines and modify it for perpendicular lines.

10. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is 2. The parallel slope is 2 and the perpendicular slope is the negative reciprocal or -1/2.

Parallel Perpendicular

(y-1)=2(x-0) (y-1)==-1/2(x-0)

y-1=2x y-1 = -1/2 x

y=2x+1 y = -1/2x +1

11. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is -1/3. The parallel slope is -1/3 and the perpendicular slope is the negative reciprocal or 3.

Parallel Perpendicular

(y-5)=-1/3(x-3) (y-5)=3(x-3)

y-5=-1/3x+1 y-5 = 3x - 9

y=-1/3x +6 y = 3x -4

12. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is -5. The parallel slope is -5 and the perpendicular slope is the negative reciprocal or 1/5.

Parallel Perpendicular

(y-2)=-5(x--4) (y-2)=1/5(x--4)

y-2=-5(x+4) y-2 = 1/5(x +4)

y-2=-5x -20 y-2 = 1/5x +4/5

y=-5x-18 y=1/5x + 14/5
