(6 - 1) + (3m)i = -12 + 27i
Yanka [14]

Answer:

We want to solve the equation:

(6 - 1) + (3m)i = -12 + 27i

Where m is a complex number.

first, we can rewrite this as:

5 + 3*m*i = -12 + 27*i

3*m*i = -12 - 5 + 27*i

3*m*i = -17 + 27*i

And we can write m as:

m = a + b*i

Replacing that in the above equation we get:

3*(a + b*i)*i = -17 + 27*i

3*a*i + 3*b*i^2 = -17 + 27*i

and we know that i^2 = -1

3*a*i - 3*b = -17 + 27*i

The real part in the left (-3*b) must be equal to the real part in the right (-17)

then:

-3*b = -17

b = -17/-3 = 17/3

And the imaginary part in the left (3*a) must be equal to the imaginary part in the right (27)

then:

3*a = 27

a = 27/3.

Then the value of m is:

m = a + b*i = (27/3)  + (17/3)*i

Solve for x<br> - 1/5 (x – 4) = -2<br> Enter your answer in the box.<br> x =
UkoKoshka [18]

-1/5 (x - 4) = -2

(-1/5)x + (4/5) = -2    

-2 can be turned into -10/5

(-1/5)x = (-10/5) - (4/5)

(-1/5)x = -14/5

multiply by -5 on both sides

x = 14

hope this helps :)

A sequence is defined by an = -5+ (n - 1) 14, where n is a positive integer. What is the value of 410?
Jobisdone [24]

The sequence an = -5 + (n - 1)14 is an arithmetic sequence

The value of a10 is 121

<h3>How to determine the the a10-th term?</h3>

The sequence is given as:

an = -5 + (n - 1)14

To calculate the value of a10, we set n = 10

So, we have:

a10 = -5 + (10 - 1) * 14

Evaluate the difference

a10 = -5 + 9 * 14

Evaluate the product

a10 = -5 + 126

Evaluate the sum

a10 = 121

Hence, the value of a10 is 121

Jim 3 bought 3 hamburgers and 4 orders of french fries for $10.77 before taxes.
Inessa [10]

Answer:

The cost of one hamburger is $2.19.

Step-by-step explanation:

Let h = cost of a hamburger

f = cost of a french fries

3h + 4f = 10.77-------->3h + 4f = 10.77

4h + 2f = 10.86------->8h + 4f = 21.72

---------------------

5h = 10.95

h = 2.19, f = 1.05
