spayn [35]

You have (-3 +i)/(7 + i) so you need to remove the i from the numerator, so you have to multiply by 7-i and you get

(-22 + 4i)/50 which can be simplified to

(-11 + 2i)/25

Ket [755]

Answer:

Step-by-step explanation:

1) Subtract the base price from the final price. 40.56 - 39 = 1.56.

2) Divide the tax by the base price to determine the decimal version of the percentage. 1.56 / 39 = 0.04.

3) Multiply this by 100 to turn it into the normal percentage. 0.04 × 100 = 4, so the answer is 4%.

<u>Question:</u>

Bradley wrote the beginning of an equation, $\frac{3}{8}x + 12 =$

Finish the equation so that the equation will have no solution. Explain how you know.

Answer:

$\frac{3}{8}x + 12 =\frac{3}{8}x -4$

Step-by-step explanation:

Given

$\frac{3}{8}x + 12 =$

Required

Complete the equation to have no solution

The given equation is a linear equation in form of $mx + b$

Where $m = \frac{3}{8}$

Compare both equations

$\frac{3}{8}x + 12 = mx + b$

Substitute $\frac{3}{8}$ for m

$\frac{3}{8}x + 12 = \frac{3}{8}x + b$

Collect Like Terms

$b = \frac{3}{8}x - \frac{3}{8}x + 12$

$b = 12$

This implies that, for the equation to have a solution the value of b must be 12.

However, for the equation not to have a solution, the value of b must not equal 12

i.e.

$b \ne 12$

This implies that, we can assume any value, other than 12 for b so that the equation will not have a solution.

Say for instance: b = -4

$\frac{3}{8}x + 12 = mx + b$

Substitute -4 for b and 3/8x for m. This gives:

$\frac{3}{8}x + 12 =\frac{3}{8}x -4$
