If 2= (1+ r)^7 solve the equation for r?​

Mathematics
1 answer:
Katarina [22]3 years ago
6 0

Answer:

r= ^7√2-1

Step-by-step explanation:

2=(1+r)^7

2=1^7 +r^7 ( 1 to the power anything is 1)

2=1+r^7

1+r^7=2

r^7=2-1

7^√r^7= ^7√2-1

r= ^7√2-1

-2x < -6
Soloha48 [4]

Answer:

x > 3

Step-by-step explanation:

This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'

*only when the number is -ve.

Similarly, in this question, multiply both sides by - 1.

2x > 6

x > 6/2

x > 3

For more : take - 5 > - 2, as you know

Note that 5 is actually greater than 2. To make this true we change signs

For each of the following state the condition that supports why quadrilateral WXYZ is a pallelogram.
Veronika [31]

  • 1.}--diagonals bisect each other
  • 2...and...3}.---two pairs of opposite sides are parallel and equal
  • 4.}--opposite angles are equal
  • 5…}---diagonals bisect each other

  • <em><u>none. I has no solutions (in all x, y and z) because in case x+y+z is 3 it can never be 4. So, it's imposible to find any (x,y,z) so that they satisfy both equations.</u></em>
  • <em><u>To find the slope, convert the equation 21x - 3y + 18 = 0 to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). To do so, first subtract 18 and 21x from both sides to get -3y = -21x - 18. Then divide both sides by -3 to get y = 7x + 6. Therefore the slope is 7.</u></em>
