Solve the following equation. 2x - 1 ≤ x 5

1 answer:

5 0

2x−1≤x5

Let's find the critical points of the inequality.

2x−1=x^5

2x−1−x^5=x^5−x^5 (Subtract x^5 from both sides)

−x^5+2x−1=0

(−x+1)(x^4+x^3+x^2+x−1)=0 (Factor left side of equation)

−x+1=0 or x^4+x^3+x^2+x−1=0 (Set factors equal to 0)

x=1 or x=0.51879 or x=−1.290649

Sphinxa [80]

Step-by-step explanation:

9(x - 11) = 9

x - 11 = 9 / 9

x - 11 = 1

x = 1 + 11

x = 12

Answer:

largest angle measures 108°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

8x - 6 + 108 + 14 = 180, simplify left side

8x + 116 = 180 ( subtract 116 from both sides )

8x = 64 ( divide both sides by 8 )

x = 8

Thus

∠ U = 8x - 6 = 8(8) - 6 = 64 - 6 = 58°

Then the largest angle measures 108° ( ∠ B )

Answer for brainliest please

cestrela7 [59]

Answer:

Scale factor = 2 for C

Scale factor = 2 for D

Scale factor = 2 for B

Step-by-step explanation:

Shape C has the dimensions of 2 x 6

Shape A has the dimensions of 1 x 3

Shape C is exactly 2 times an englargement of A because:

multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of C)

multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of C)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Shape D has the dimensions of 2 x 6

Shape A has the demensions of 1 x 3

Shape D is exactly 2 times an englargement of A because (same as C):

multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of D)

multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of D)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Shape B has the dimensions of 3 x 9

Shape A has the demensions of 1 x 3

Shape B is exactly 3 times an englargement of A because:

multiply 1 (dimension of A) times 3 (scale factors) = 3 (dimension of B)

multiply 3 (dimension of A) times 3 (scale factors) = 9 (dimension of B)

Una maquina teje en un dia 1/8 de una pieza de 96 metros al dia siguiente teje los 2/7 de lo que quedo por tejer el dia anterior

Alexandra [31]

Answer:

D: 36 meters

Step-by-step explanation:

Given that

A machine weaves 1 by 8 of a 96 meter on one day

On next day it weaves 2 by 7 of what was left

We need to find out the number of meter woved in these two days

So for first day, it is

= 1 ÷ 8 × 96 meter

= 12 meter

In the second day, it is

= (96 - 12 meter) × 2 ÷ 7

= 24 meter

So, the total woved in these two days

= 12 meter + 24 meter

= 36 meter

Hence, the option d is correct
