Multiplying

(2 + 3i)(2 - 3i)

4 - 6i + 6i - 9i^2

4 - 12i + 9

13 - 12i

Add/subtract

2 - 3i + 2 + 3i = 2

2 - 3i - (2 + 3i) = 2 - 3i - 2 - 3i = -6i

Answer:

x + 2y

Step-by-step explanation:

Step 1: Write expression

Answer:

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

12 = 7x + 6 -5x        {Combine like terms}

12 = 7x - 5x + 6

12 = 2x + 6           {Subtract 6 from both sides}

12 - 6 = 2x

      6 = 2x                  {Divide both sides by 2}

    6/2 = 2x/2

3 = x

x = 3

$8.33 per soccer ball.

Step-by-step explanation:

Y max is =236.67   is the max profit from the soccer balls. This goes on when you charge 8.33 a ball

Answer:

need to solve the equation 150 = -6x2 + 100x - 180. I can subtract 150 from both sides and use the quadratic formula to find x = 4.53 and 12.13. This means that if the store sells soccer balls for $4.53 or $12.13, it will earn a daily profit of $150.

Answer:

8^4

Step-by-step explanation:

A 'base' is a number with an exponent.

The expression [tex]8^4[/tex] has the base 8.

We need to find which of the given term has an expression with a base of 8.

A numerical system's number basis, or base for short, informs us of the particular or distinctive symbols and notations it employs to express a value. The number used to construct a power with an exponent, such as the 3 in 3², is known as the base.

In the expression [tex]8^4[/tex], 8 is the base and 4 is the power or exponent.

Therefore, the expression [tex]8^4[/tex] has the base 8.

Correct from Edmentum

Answer:

_________

z is 48

x is 48

y is 132

_________

Answer:

x+132=180 [ linear pair]

x=180-132=48

y=132[ opposite angles]

z=x=48 [ opposite angles]

if we add all these four angles we get 360 degree.

Answer:

Step-by-step explanation:

each mark represents 0.25

Decimal value positioned at point B is -2.25

A number system is defined as a system of writing to express numbers.

A number line can be defined as a pictorial representation of numbers on a straight line.

In the given number line each line represents 0.25 (zero point two five value).

As B is in between -2 and -3.

So B value is between minus two and minus three

The values which can be between -2 and -3 are -2.25, -2.5, -2.75.

The decimal value positioned at point B is -2.25

Hence decimal value positioned at point B is -2.25

Answer:

x = -2±i

Step-by-step explanation:

Answer:

x>-2

Step-by-step explanation:

first you subtract 10 from both sides to find x

10-3x-10<16-10

-3x<6

now here you divide both sides by -3

-3x/-3<6/-3

BUT since you are dividing by a negative number the sign will have to flip

so the answer will be

x>-2

Answer:

D. 80

Step-by-step explanation:

Given:

f(x) = 5x - 4,

g(x) = x² - 1

Required:

(g o f)(-1)

SOLUTION:

(g o f)(-1) = g(f(-1))

Plug in -1 for x into the function, f(x) = 5x - 4:

g(f(-1)) = g(5(-1) - 4)

= g(-5 - 4)

= g(-9)

Plug in -9 for x in the function, g(x) = x² - 1

g(-9) = (-9)² - 1

= 81 - 1

= 80.

Therefore, (g o f)(-1) = g(f(-1)) = 80

D. 80 is the correct answer.
