Multiply (8 + 3i)(3 + 5i)
svetoff [14.1K]
12+49i
when you get i^2 it's the same as multiplying by -1 so 
factoring it out will turn out like this
15i^2+40i+9i+27
instead of 15 i^2 multiply 15 x-1
-15+49i+27
12+49i

For what values of x would the following be true?<br> -2(x-3)&lt;4
emmainna [20.7K]

Answer:

x > 1

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

-2(x - 3) < 4

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide -2 on both sides:                    x - 3 > -2
  2. Add 3 to both sides:                          x > 1

Here we see that any value <em>x</em> greater than 1 would work as a solution to the equation.

Which of the following points is a solution to the system of equations shown?
Llana [10]

Answer: First Option (2,-7)

Step-by-step explanation:

We have a system of equations formed by the following equations:

x + y = -5\\\\4x + y = 1

To answer this question we must solve the system of equations. There are several ways to solve it. The easiest way to solve it for this case is to multiply the second equation by -1 and then add it to the first equation.

\ \ \ x + y = -5\\-4x - y = -1

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

-3x + 0 = -6\\\\x = 2

Now substitute x = 2 in any of the system equations and solve for y.

2 + y = -5\\\\y = -7

Therefore the solution of the system is the point: (2, -7)

Sketch the graphs of the line system on a corporate:{2x-y=1} {y=5x-5}
Papessa [141]
I don’t know what some of that means but I can do the start for you? You rearrange
2x-y=1.

To do this, you +y to both sides, giving you 2x=1+y and then you minus 1, giving you 2x-1=y

Which can be rewritten the other way round to make it slightly easier

y=2x-1

You also have y=5x-5

These are both straight line equations and are now in the form y=mx+c

To sketch these graphs I would do two tables.

X -3 -2 -1 0 1 2 3
Y

For this, you now substitute each of the values for X into one of the equations you have. This is 2x-y=1 (2x-1=y)


X -3 -2 -1 0 1 2 3
Y -7 -5 -3 -1 1 3 5

You may have noticed a pattern there, the y values increased by two each time. This makes it linear. You would plot that line, onto an axis, using the coordinates you now have.
So, (-3, -7), (-2,-5), (-1,-3), (0,-1), (1,1), (2,3), (3,5)

Then I would do the same for the second equation, and plot that too.


X -3 -2 -1 0 1 2 3
Y -20 -15 -10 -5 0 5 10

You may have spotted this time the values increased by 5.

Then again plot this line using the coordinates shown.

I honestly have no idea what it means by “the line system on a corporate” but if that means on an axis then there’s your answer. If not then I do not know.

Hope this helps?
