2x+3-3=-6<br><br><br><br> x=3 ? Solve
ivann1987 [24]

2(x)+3-3=-6\\2(3)+3-3=-6\\6+3-3=-6\\6=-6\\

x\neq 3

As we can see, x cannot be equal to 3 as 6 cannot equal -6.

I hope I've helped! :)

Complete the equation so that it has solutions of –5 and 7. x2 x = 0
Pavlova-9 [17]

The equation it has solutions of –5 and 7  is x^2-2x-37=0

We have equation

solutions of equation are –5 and 7.

We have to find complete the equation.

We have given that solutions of the equation are -5, 7.

The standard form of a quadratic equation.

<h3>What is the factor of the quadratic equation?</h3>

(x -\alpha) (x- \beta)

Where we have

p = -(\alpha+\beta)  and q = (\alpha\times \beta)

So, roots are

( x- (-5)) (x-7)

p = -( -5+7) , q =(-5)(7).

p = -2  and q = -35.

On substituting p and q in equation

x^2+(-2)x-37=0

x^2-2x-37=0

Therefore,x^2-2x-37=0  is the equation of solution -5,7.

There are no results for The impedance Z in an AC (alternating current) circuit is a measure of how much the circuit impedes (hi
Semmy [17]

Answer:

Step-by-step explanation:

If the impedance is related to the voltage and the current by the formula V = IZ where;

V is the voltage

I is the current

Z is the impedance

Given

I = 0.4+3i

V = 0.3-2i

Voltage V = (0.4+3i)(0.3-2i)

V = 0.4(0.3)-0.8i+0.9i-6i²

V = 0.12+0.1i -6i²

Since i² = -1

V = 0.12+0.1i-6(-1)

V = 0.12+0.1i+6

V = 6.12+0.1i.

Hence the impedance is 6.12+0.1i
