Find the values of x and y for 3x + 2iy = 6 + 10i

Mathematics
2 answers:
Evgen [1.6K]3 years ago

In this question, the given equation is

3x + 2yi = 6 + 10i

To solve for x and y, we have to compare both sides, and on doing so, we will get

3x=6, 2y=10

Now we need to isolate x and y, by getting rid of 3 and 2 , that is with x and y respectively .

x=2, y=5

So for the given equation to be true, the values of x and y are 2 and 5 respectively .

Answer:  The required values are x = 2  and  y = 5.

Step-by-step explanation:  We are given to find the values of x and y from the following equation :

3x+2iy=6+10i~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the values of x and y from the given equation, we need to compare the real and imaginary parts of the equation.

After comparing the real and imaginary parts from both sides of equation (i), we get

3x=6\\\\\Rightarrow x=\dfrac{6}{3}\\\\\Rightarrow x=2

and

2y=10\\\\\Rightarrow y=\dfrac{10}{2}\\\\\Rightarrow y=5.

Thus, the required values are x = 2  and  y = 5.

A light bulb consumes 2400 watt-hours per day. how long does it take to consume 9000 watt- hours?
Luden [163]

Answer:

3.75

Step-by-step explanation:

Set up the following ratio:

2400 watt-hours           1 day

-------------------------   =    ----------

9000 watt-hours           x days

Then do criss-cross-apple-sauce:

x*2400=9000*1

And then solve for x:

2400x=9000

x=9000/2400

x=3.75

Check my Work: Factoring for 2y^+9y-18 is (2y-3) (y+6) true or false?
Alexxandr [17]

It is true because when you separate 2y^2 +9y -18, you are supposed to get the factors (2y-3)(y+6), when you multiply this it gives you the first equation, we know this because when we multiply the first term it gives us exactly 2y^2 and if we multiply the last ones it gives you -18, now here is the tricky part, when we multiply the middle part we get 12y and -3y, when we add these up we get 9y, now is that the same middle as in the equation? Yes… then our factors are correct making this true


Hope this helps
