Simplify The Equation X= -4 Plus Or Minus The Square Root Of -16 All Over 2

Answers

Answer 1
x = -2+2i
or
x = -2-2i
Answer 2

Answer:

[tex]x = \frac{ - 4 \frac{ + }{} \sqrt{ - 16} }{2} \\ \\ x = \frac{ - 4}{2} \frac{ + }{} \frac{ \sqrt{ - 16} }{2} \\ \\ x = \frac{ - 4}{2} \frac{ + }{} \frac{ \sqrt{16} \sqrt{ - 1} }{2} \\ \\ x = \frac{ - 4}{2} \frac{ + }{} \frac{4i}{2} \\ \\ x = - 2 \frac{ + }{} 2i[/tex]

x = – 2 + 2i , x = – 2 – 2i

we're doing literal equations in math and i dont understand how i would solve this question, please help!

Answers

Answer:

x = -4u/3

Step-by-step explanation:

The first step is to create a fraction on both sides in order to prepare for cross-multiplication.

Cross-multiplication is a shortcut for the following technique, shown by this example.

a/b=c/d

Multiplying both sides of the equation by bd using the multiplication property of equality will then grant the equation ad = bc, and then a single component can be isolated by creating the equation a = bc/d for example using the division property of equality.

Back to cross-multiplication, however, creating a fraction of both sides can be achieved by creating the equation u/1 = -3x/4, since any number divided by 1 is equal to itself.

Then, by cross-multiplying u and 4 and 1 and -3x, you get the equation 4u = -3x.

Dividing both sides by -3 will then grant the final answer of x = -4u/3.

Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent error?

Answers

Answer:

The answer is 10.42 %

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]

We have the final answer as

10.42 %

The solution is, C. (1, 5), ordered pair is a solution to the system of inequalities.

Here, we have,

We have the following system of inequalities:

y> 2x

y> 3

We graph each inequality and obtain the following:

Now we graph each point and the one that remains inside the purple zone, would be the system solution, like this:

We can see that the only option that remains within the point zone is the point (1, 5)

therefore, the correct answer is C. (1, 5)

Answers

Answer:

6

Step-by-step explanation:

7x + 3(-x + 6) = 42

use distributive property

7x + -3x + 18 = 42

positive + negative = negative

7x - 3x + 18 = 42

combine like terms

4x + 18 = 42

subtract 18 from both sides

4x + 18 - 18 = 42 - 18

18 is canceled out on the left side

4x + 0 = 24

4x = 24

divide both sides by 4

4x ÷ 4 = 24 ÷ 4

1x = 6

x = 6
