what is the slope of the following line 3x+2y=300
Answer: We have m = −3/2 as the slope and b = 150 as the y-intercept.
Step-by-step explanation:
Given data,
The slope of the following line 3x+2y=300
Define Slope :
Slope = (Change in height)/(Change in width) Or: Slope = rise/run. If y represents the vertical direction on a graph, and x represents the horizontal direction, then this formula becomes: Slope = (Change in y)/(Change in x)
The equation of a line presents the relationship between the components of a line in a certain coordinate system. To construct the equation of the line, we must take note of the parameters such as the slope, a point at which the line passes through, and the intercepts.
We solve for the slope, m, and the y-intercept, b, for the given line. We do this by rewriting the expression into the slope-intercept form,
y = mx + b
We proceed with isolating y in the given equation.
3x + 2y = 300
2y = - 3x + 300
y = (-3x + 300) / 2
y = (-3/2) x + 300/2
y = (-3/2) x + 150
Therefore, we have m = −3/2 as the slope and b = 150 as the y-intercept.
So, slope = -3/2
b = 150

The monthly payment become $852. Thus , option C is correct option.
According to the statement
We have to find that the monthly repayment.
So, For this purpose, we know that the
The monthly payment is the amount paid per month to pay off the loan in the time period of the loan.
From the given information:
You have decided to buy a new home and the bank offers you a 30 year fixed loan at 5.5% on a balance of $150,000.
Then
we know that the:
Monthly payment = Amount / discount factor
And discount factor = 1-(1+i)^-n / i
Then
M = A*i/1-(1+i)^-n
Where, A=$150000
r=5.5%=0.055
i = 0.555/12
i = 0.004
And t = 30 year
n = 30*12
n = 360
Substitute all the values,
M = 150000*0.004/ 1-(1+0.004)^-360
M = 687.5 / 1-0.192
M = 687.5 / 0.80722
M = 851.7
Approximately, Monthly payment is $852.

Please help me understand the zero factor property with this problem. I understand the property when the equations have parentheses, but not when they don’t. I know the answer I just need help explaining! Thank you!
Two ways to do this! There are some more but these are the most intuitive.
Way 1: Factoring
You can factor this equation into one with parentheses. A way I like thinking of doing this is by seeing if you can split the coefficient of the middle term into the sum of two numbers, which, when multiplied with each other, equal the third term. To see what I mean, look at the equation you gave.
[tex]x^2 - 18x + 77 = 0[/tex]
[tex]x^2 - 7x - 11x + 77 = 0[/tex]
We notice that when -7 and -11 are multiplied, they equal 77. This means we can factor the equation! As follows:
[tex](x-7)(x-11)=0[/tex]
If you want to see why this works, cross-multiply out [tex](x-7)(x-11)[/tex]. You should see that it is equal to [tex]x^2 - 7x - 11x + 77[/tex].
From here, you should be able to see the solutions are [tex]x = 7, 11[/tex].
Way 2: Complete the Square
We can do something like this:
[tex]x^2 - 18x + 77 = 0\\x^2 - 18x + 81 = 4\\(x-9)^2 = 4\\x-9 = \pm\sqrt{4}\\x = 9\pm 2\\x = 7, 11[/tex]
Essentially, what we are doing is we are adding / subtracting from both sides of the equation so the left side becomes a perfect square of some term [tex](x-a)[/tex]. From there, we can just solve for [tex]x[/tex].
Hope this helps you, please let me know if anything confuses you.

A relation could be a function or it could not.What is a relation simple definition?
A collection of ordered pairs having one item from each set makes up a relation between two sets. If the ordered pair (x,y) is present in the relation and the objects x and y come from different sets, then the objects are said to be connected. One kind of relation is a function.H={(6, - 2), (5,- 2), (4, -2), (3, - 2), (2, - 2)}

find the general form of the quadratic function with the vertex (1,4) and a point on the graph (-3,20)
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.
How to find the general form of the quadratic function
In this question we must derive the equation of the parabola in vertex form, whose description is shown below:
4 · p · (y - k) = (x - h)² (1)
Where:
(h, k) - Coordinates of the vertex.(x, y) - Coordinates of a point of the parabola.p - Distance from vertex to focus.If we know that (h, k) = (1, 4) and (x, y) = (- 3, 20), then the distance from vertex to focus is:
p = (x - h) / [4 · (y - k)]
p = (- 3 - 1)² / [4 · (20 - 4)]
p = (- 4)² / 64
p = 16 / 64
p = 1 / 4
Then, the equation of the parabola in vertex form is y - 4 = (x - 1)². And now we find the general form of the quadratic formula, that is:
A · x² + B · x + C · y + D = 0 (2)
Then, we proceed to obtain the general form:
y - 4 = (x - 1)²
y - 4 = x² - 2 · x + 1
x² - 2 · x - y + 5 = 0
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.
