Answer:
<h2>7x - 4y + 18 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
========================================
Let
========================================
We have the equation of a line in a general form (Ax + By + C = 0)
Convert it to the slope-intercept form:
<em>subtract 7y from both sides</em>
<em>divide both sides by (-7)</em>
Therefore
We have the equation:
Put the coordinates of the point (-2, 1) to the equation, and solve for <em>b</em> :
<em>multiply both sides by 2</em>
<em>add 7 to both sides</em>
<em>divide both sides by 2</em>
[te]x\dfrac{9}{2}=b\to b=\dfrac{9}{2}[/tex]
Finally:
- <em>slope-intercept form</em>
Convert to the general form:
<em>multiply both sides by 4</em>
<em>subtract 4y from both sides</em>
Answer:
Random sampling
Step-by-step explanation:
Random sampling is a method of choosing a sample of observations from a population to make assumptions about the population. It is also called probability sampling.
Answer:
b=-3
Step-by-step explanation:
If the expression simplifies to bx that means the terms and the constant terms must be cancel out.
Simplify it first.
We know –4 + 4 will cancel out. If we simplify this expression to only an x term, then the terms should be cancelled. Therefore, we say that 4ax^2 – x^2 = 0.
If we put a = ¼, then we can find the value of b:
if the expression is equivalent to bx
Therefore, b = –3.
3 of 5 because you can halve each number for example 6 can be halved to make 3 and 10 can be halved to make 5
The factors of 117 are: 1, 3, 9, 13, 39, and 117
The factors of 99 are: 1, 3, 9, 11, 33, and 99
