Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations. Hint: Use
Natasha2012 [34]
I^3=-i
therefor -27i=(3i)^3
so we can get a sum of 2 perfect cubes
a^3+b^3=(a+b)(a^2-ab+b^2)

so
remember that i²=-1
x^3+(3i)^3=(x+3i)(x²-3xi-1)

What is the equation of a line perpendicular to why=2x-6 that passes through (5,4)
almond37 [142]

Answer:

y = ½(13- x)

Step-by-step explanation:

Step 1. Find the<em> slope (m₁) of the original line </em>

The equation for the original line is

      y = 2x - 6

slope = m₁ = 2

Step 2. Find the <em>slope (m₂) of the perpendicular line </em>

m₂ = -1/m₁     Substitute the value of m₁

m₂ = -1/2

Step 3. Find the <em>equation for the perpendicular line</em>

y = mx + b     Substitute the value of m₂

y = -½x + b

The line passes through (5, 4).  

4 = -½(5) + b     Add 5/2 to each side

4 = -5/2 + b     Add 2 to each side

b = 13/2  

y = -½x + 13/2

y = ½(13 – x)  

In the image, below, the red line is the graph of your original equation.

The blue line passing through (5, 4) is the perpendicular line.

Use related facts to determine whether the given value is a solution for each equation
solong [7]
For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.
Hope this helps Xx

Can someone help out?
Crank

Answer:

b ≥ 5,000.

Step-by-step explanation:

1. Use the information given in the problem to write the inequality... such as box tops & the amount of 5,000 box tops.

2. b represents the number of  box tops for the fundraiser. Therefore, based on the information provided, the value of b must be greater than or equal to 5,000 box tops. So, you get the inequality is:

b ≥ 5,000

3. Then you graph it, you must use a closed circle for ≥.

~~(the graph is different, but you should be able to understand it.)

hopefully my answer helps! ♡

if my answers helped you please tell me, therefore I know.. that I did them correctly or incorrectly. anyways, have a great day/night!
