Answer:

Step-by-step explanation:

An even number is a number divisible by 2 and be an integer. An example would be 4/2 = 2

An incorrect even number would be 5

5/2 = 2.5 which isn't odd or even because it isn't an integer.

Given z1 = 1+i and z2 = 2+3i.

Margaret [11]

Answer:

(a) $w=2+5i-6=-4+5i$

Multiplicative inverse of w will be $\frac{1}{-4+5i}$

(B) As w is same as the product of $z_1\ and\ z_2$

So there multiplicative inverse will also be same

Step-by-step explanation:

We have given two complex numbers

$z_1=1+i$ and $z_2=3+2i$

(a) First we have to find $w=z_1z_2$

So $w=(1+i)(2+3i)=2+3i+2i+6i^2=2+5i+6i^2$

As we know that $i^2=-1$

So $w=2+5i-6=-4+5i$

Multiplicative inverse :

It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1

So multiplicative inverse of w will be $\frac{1}{-4+5i}$

Because when we multiply $-4+5i$ with $\frac{1}{-4+5i}$ it gives result as 1

(b) As w is same as the product of $z_1\ and\ z_2$

So there multiplicative inverse will also be same

Can you find the slope -intercept equation of each line code ?

ikadub [295]

Answer:

You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.

Step-by-step explanation:

The Slope-Intercept Form Formula: y=mx+b

The m represents the slope while the b represents the y-intercept

You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.

Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.

Sketch a graph of f(x)

just olya [345]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

For $x\leq -2$ -----> the interval is (-∞,-2]

$f(x)=-3$

For $-2 < x \leq 1$ -----> the interval is (-2,1]

$f(x)=x$

For $x > 1$ -----> the interval is (1,∞)

$f(x)=2$
