Answer:

r= -5 , r= 17

Step-by-step explanation:

5|-6+r|=55

solve for 'r'

First we isolate absolute function

We divide both sides by 5

|-6+r| = 11

for absolute function we consider two cases, one with positive and one with negative. Now we make two equations

-6+r = 11   or -6+r = -11

Now solve both equations

-6 + r= 11

Add 6 on both sides

so , r= 17

-6 + r= -11

add 6 on both sides , so r= -5

Which of the following is a solution to tan^2 x-1=0? a.45 degrees, b.120 degrees, c.240 degrees, d.330 degrees
andrew-mc [135]
Do you want a general solution or from 0 <= x < 2pi?

tan^2(2x) - 1 = 0
tan^2(2x) = 1

Take the square root of both sides,

tan(2x) = +/- 1

Two equations:
tan(2x) = 1
tan(2x) = -1

Solve each equation.

tan(2x) = 1, 2x = {pi/4, 5pi/4, 9pi/4, 13pi/4},
x = { pi/8, 5pi/8, 9pi/8, 13pi/8 }

tan(2x) = -1, 2x = { 3pi/4, 7pi/4, 11pi/4, 15pi/4 },
x = { 3pi/8, 7pi/8, 11pi/8, 15pi/8}

So for solutions within [0, 2pi),

x = {pi/8, 3pi/8, 5pi/8, 7pi/8, 9pi/8, 11pi/8, 13pi/8, 15pi/8 }

Help... anyone????????
katovenus [111]
Since they both have 3x terms subtract the second from the first to get rid of the x terms...

  3x+2y=10
-3x+y=-13
__________
3y=-3

y=-1, which makes 3x+2y=10 become: 3x-2=10 so

x=4

So the solution is the point (4, -1)

If it takes 6.9 pounds of seed to plant one acre of grass , how many acres can be planted with 8.28 pounds of seeds
Vaselesa [24]
There's 1.2 times as much seed, so you can plant 1.2 times more land.

1.2x1=1.2

So you can only plant 1.2 acres.
