What is the solution set of the equation<br> 3X=-6/1-X<br> for x # 1?

Irina-Kira [14]

The solution set of the equation 3X=-6/1-X for x # 1 is {-2,1)

3x = -6/(1-x)

3x(1-x) = -6

3x – 3x2 = -6

Taking 3 as common from both sides

x –x2 = -2

x2 – x +2 =0

Using factorisation method we will get two factors

Factoring quadratics is a method of expressing the quadratic equation ax2 + bx + c = 0 as a product of its linear factors as (x - k)(x - h), where h, k are the roots of the quadratic equation ax2 + bx + c = 0. This method is also is called the method of factorization of quadratic equations. Factorization of quadratic equations can be done using different methods such as splitting the middle term, using the quadratic formula, completing the squares, etc.

( x – 2)(x+1)=0

So, x = 2 , -1

Now, when x ≠ 1

The solution of the equation will vary from {-2,1) .

Pythagorean Triad. Numbers are 43 and 38, what is the last number?

Stella [2.4K]

We are given

isosceles triangle

and when we draw perpendicular on third sides , it will divide third sides into two equal parts

so,

opposite =38

adjacent =x/2

hypotenuse =43

now, we can use Pythagoras theorem

$38^2+(\frac{x}{2})^2=43^2$

now, we can solve for x

$\left(\frac{x}{2}\right)^2=405$

Answer:

Kindly check explanation

Step-by-step explanation:

(a) What scale is used to measure delivery performance?

Ordinal scale was used because their is an hierarchical arrangement in the delivery performance. Arrangement in order of promptness(EARLY - - > ON TIME - - > LATE - - > LOST)

What kind of variable is delivery performance?

Qualitative variable due to the non-numeric nature of its representation.

B.)

(b) Construct a frequency table for delivery performance for last month.

Performance ___Frequency

Early ____________23

On-time _________ 68

Late _____________8

Lost _____________ 1

Performance ___Frequency ___R/frequency

Early ____________23 ___23/100 = 0.23

On-time _________ 68 ___68/100 = 0.68

Late _____________8 ____8/100 = 0.08

Lost _____________ 1 _____1/100 = 0.01

Percentage (%) Packages either early or on time :

(0.23 + 0.68) = 0.91 = 91

Late packages (%) = 0.08 = 8

Lost packages (%) = 0.01 = 1
