ValentinkaMS [17]

Answer:

3x + 4 = 9x -6
3x + 4 = 3x + 5
9x + 6 = 9x + 6

Step-by-step explanation:

Let x is the variable in each type of equation

1/ an equation that has one solution:

3x + 4 = 9x -6

<=> 9x - 3x = 4+6

<=> 6x = 10

<=> x = $\frac{10}{6}$

2/ an equation that has no solution:

3x + 4 = 3x + 5

<=> 3x - 3x = 5-4

<=> 0 = 1 impossible

3/ an equation that has infinite many solutions:

9x + 6 = 9x + 6

<=> 9x - 9x = 6 -6

<=> 0 = 0 (obvious) no matter what we put in for x

Hope it will find you well.

g 7. Find Re f and Im f and find their values at the given z. (Both answers should be included) f = z⁄(z + 1), z = 4 − 5

Schach [20]

Answer:

The real and imaginary parts of the result are $\frac{1441}{1601}$ and $\frac{4}{1601}$ , respectively.

Step-by-step explanation:

Let be $f(z) = \frac{z}{z+1}$ , the following expression is expanded by algebraic means:

$f(z) = \frac{z\cdot (z-1)}{(z+1)\cdot (z-1)}$

$f(z) = \frac{z^{2}-z}{z^{2}-1}$

$f(z) = \frac{z^{2}}{z^{2}-1}-\frac{z}{z^{2}-1}$

If $z = 4 - i5$ , then:

$z^{2} = (4-i5)\cdot (4-i5)$

$z^{2} = 16-i20-i20-(-1)\cdot (25)$

$z^{2} = 41 - i40$

Then, the variable is substituted in the equation and simplified:

$f(z) = \frac{41-i40}{41-i39} -\frac{4-i5}{41-i39}$

$f(z) = \frac{37-i35}{41-i39}$

$f(z) = \frac{(37-i35)\cdot (41+i39)}{(41-i39)\cdot (41+i39)}$

$f(z) = \frac{1517-i1435+i1443+1365}{3202}$

$f(z) = \frac{2882+i8}{3202}$

$f(z) = \frac{1441}{1601} + i\frac{4}{1601}$

The real and imaginary parts of the result are $\frac{1441}{1601}$ and $\frac{4}{1601}$ , respectively.

find the grouping method to factor the polynomial in the box completely. Use the caret symbol (^) to write the exponent; for exa

sineoko [7]

We start with the polynomial

3x^4 + 12x^3 +27x

Now we search for the common term, in this case it is 3x and factor it out:

3x(x^3+4x^2+9)

Notice that x^3+4x^2+9 cannot be factored anymore then the factorization of the polynomial is:

3x(x^3+4x^2+9)
