What is an equation that goes through (12, 5); m = -3
Please help
Answer:
Step-by-step explanation:
Use this formula:
y - y1 = m ( x - x1 )
We are told m = -3 and given the point (12 , 5) ---- > so x1 = 12 and y1= 5
Put these values into the formula above and you get:
y - y1 = m ( x - x1 )
y - 5 = -3 ( x - 12 )
y - 5 = -3x + 36
y = -3x + 36 + 5
y = -3x + 41

The standard deviation of a density curve is indicated by Sx.
The density curve can be above and below the x-axis.
Answer:
The mean of a density curve is indicated by µ.
The standard deviation of a density curve is indicated by σ.
This is the answer Egde 2020
The statements which are true about density curves is the mean of a density curve is indicated by u and the standard deviation of a density curve is indicated by Sx.
What is a density curve?
The density curve is a way of representation of numerical distribution data in graphical manner, where the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.
In a density curve,
The mean of a density curve is indicated by μ (mu).The standard deviation of a density curve is indicated by Sx.The density curve can only be above x-axis and not below it.Thus, the statements which are true about density curves is the mean of a density curve is indicated by u and the standard deviation of a density curve is indicated by Sx.

5a+8+(-2a)=-7
I need help with this question especially because of the parenthesis
Answer:
5a+8+(-2a)=-7
5a+8-2a=-7
5a-2a=-7-8
3a=-15
3a/3=-15/3
a=-5
Answer:
a = -5
Step-by-step explanation:
Simplify both sides:
5a + 8 + (-2a) = -7
(5a + -2a) + 8 = -7
3a + 8 = -7
Start solving for a by subtracting 8 from both sides
3a+8-8 = -7 - 8
3a = -15
Next, divide both sides by 3
3a/3 = 1
-15/3 = -5
a = -5

idrk exactly how to explain it....but i'll try....
the 87 is part of a straight angle, so the one to the left of it, that angle is 93.
1 is diagnoly oppisite of the 87, so 1 is 87. 2 is diagnoly oppisite of the other part of the striaght angle(93), so its 93
The equation of a line is y = -3x – 2. What are the slope and the y-intercept of the line?
A.
slope = -3 and y-intercept = 2
B.
slope = 3 and y-intercept = -2
C.
slope = 3 and y-intercept = 2
D.
slope = -3 and y-intercept = -2
The slope of the line is - 3 and the y - intercept of the line is - 2.
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of line is,
⇒ y = - 3x - 2
We know that;
The slope - intercept form of the equation of line is,
⇒ y = mx + b
Where, m is slope and b is y - intercept.
So, By comparing we get;
The slope (m) of the line = - 3
And, the y - intercept of the line = - 2.

As the exponent on the base 10 increases, does
the standard notation number get larger or
smaller in value? Explain why.
Help Please
Answer:
Since the exponent on 10 is positive, I know they are looking for a LARGE number, so I'll need to move the decimal point to the right, in order to make the number LARGER. Since the exponent on 10 is "12", I'll need to move the decimal point twelve places over.
First, I'll move the decimal point twelve places over. I make little loops when I count off the places, to keep track:
3.6 _ _ _ _ _ _ _ _ _ _ _ .
Then I fill in the loops with zeroes:
3.600000000000.
In other words, the number is 3,600,000,000,000, or 3.6 trillion
Step-by-step explanation:
[tex]10^{x}[/tex]
Where:
10 = Base 10
x = Exponent
When the exponent on the base 10 increases, the standard notation number gets larger in value. This is because the exponent is directly proportional to the size of the standard notation of the number.For example:
[tex]10^{2} = 100[/tex]
[tex]10^{3} = 1000[/tex]
[tex]10^{8} = 100000000[/tex]
