If a = 2 + i, and b = 3 – 2i, whats b/a?

1 answer:

3 0

Hello :
b/a = (3-2i)/(2+i)
= (3-2i)(2-i)/(2+i)(2-i)
= (3-2i)(2-i)/(2²-i²) .......i² = -1
= (6-3i-4i -2)/5
=(4 -7i)/5
b/a = (4/5)-(7/5) i

Identify the inequalities A, B, and C for which the given ordered pair is a solution: (0,0)

professor190 [17]

Answer:

Options (A) and (C)

Step-by-step explanation:

A). The given inequality is,

x + y ≤ 2

Solution area of the inequality is the shaded area below the line.

Since (0, 0) lies in the shaded region, ordered pair will be a solution of this inequality.

B). For the inequality y ≤ $\frac{3}{2}x-1$

Since, (0, 0) doesn't lie in the shaded region of this inequality, ordered pair will not be a solution of the inequality.

C). y > $-\frac{1}{3}x-2$

In this graph (0, 0) lies in the shaded region of the inequality therefore, it will be a solution of the given inequality.

Therefore, Options (A) and (C) are the correct options.

Can someone give the answer

KonstantinChe [14]

Answer:

(2, -2)

Step-by-step explanation:

Given the equation

x - y = 4 ... 1

6x+y = 10 ...2

Add both expressions

x+6x = 4 + 10

7x = 14

x = 14/7

x = 2

Substitute x = 2 into equation 1;

From 1;

x - y = 4

2 - y = 4

y = 2-4

y = -2

Hence the solution to the system of equation is (2, -2)
