Which line is parallel to the line 5 x+6 y=30 ?
f. 5 x+9 y=30
g. 9 x+6 y=30
h. 5 x+6 y=9
i. 6 x+5 y=30
The equation of the line h. 5x + 6y = 9 is parallel with the equation of the line 5x + 6y = 30.
Two lines are parallel with each other if they do not intersect no matter how much you extend both lines. Parallel lines have equal slopes.
The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points. In an equation in slope-intercept form, y = mx + b, the slope, m is the coefficient of x.
Determine the slope of the given line and each given choices by transforming each into slope-intercept form.
5x + 6y = 30
6y = -5x + 30
y = -5/6 x + 30/6
y = -5/6 x + 5
m = -5/6
f. 5x + 9y = 30
9y = -5x + 30
y = -5/9 x + 30/9
y = -5/9 x + 10/3
m = -5/9
g. 9x + 6y = 30
6y = -9x + 30
y = -9/6 x + 30/6
y = -3/2 x + 5
m = -3/2
h. 5x + 6y = 9
6y = -5x + 9
y = -5/6 x + 9/6
y = -5/6 x + 3/2
m = -5/6
i. 6x + 5y = 30
5y = -6x + 30
y = -6/5 x + 30/5
y = -6/5 x + 6
m = -6/5
Since h. 5x + 6y = 9 has a slope of -5/6 and equal to the slope of the given line, then they are parallel lines.

Explain how point-slope form is related to the formula for slope.
The point slope form finds the equation of a straight line that passes through a given point and is inclined to the x-axis. Each point on a line must satisfy the line's equation. Two-variable linear equations symbolize lines. The point slope formula is utilized when we know the line's slope and a point. The next section explains the point slope form and how to calculate its formula.
The equation of a straight line that is inclined at a particular angle to the x-axis and passes at a given point may be found by using the point slope form. This form is used to get the equation of the line. An equation may be said to be the equation of a line if it can be shown to be fulfilled by every point along the line. This indicates that a line is represented by a linear equation that has two variables. Whereas the Point slope formula is only used in situations in which both the slope of the line and a point on the line are known. In the next part, let's get more in-depth knowledge about the point slope form as well as how to derive the formula that is used to express the point slope form.

Suppose you use the origin to test whether a linear equation is a direct variation function. Does this method work? Support your answer with an example.
The linear equation with a direct variation function always passes through the origin.
What are direct variation functions?
The direct variation function defines a linear function of the form y = kx, where y varies as a multiple of x and x 0. These always follow the origin test.
Calculation
Yes, the method will always work because the linear equations having direct variations are those equations which always pass through the origin.
For example: If we consider an equation y = 3x. Then, it will always pass through the origin as y changes with respect to some multiples of x.
Hence, the direct variation function always passes through the origin.

Find the first term, a₁, of the sequence.
Answer:
a₁ = 15
Step-by-step explanation:
the sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
given S₁₄ = - 63 , then
[tex]\frac{14}{2}[/tex] [ 2a₁ + 13d ] = - 63
7(2a₁ + 13d) = - 63 ( divide both sides by 7 )
2a₁ + 13d = - 9 → (1)
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
given a₁₄ = - 24 , then
a₁ + 13d = - 24 → (2)

Step-by-step explanation:
Find the equation of a line passing through (2,2) and perpendicular to -x+3y=-6. Write your answer in slope-intercept form and leave all numbers as a reduced fraction
The line's equation is y=3x-4.
What is Equation of line?
Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation where the slope of line is m and b is the y- intercept. The slope is defined as
m = (y-y1)/(x-x1)
Given:
For two lines to be perpendicular to each other, they must have slopes that are negative reciprocals of each other (i.e. the negative reciprocal of n is -1/n). The slope of the given line is –1/3 which means the slope of a line perpendicular to it would be 3.
From the given slope equation of the line
y=3x+b,
where b is the y-intercept. Since we know the line passes through the point (2,2).
(y-2)/(x-2) = 3
y-2 = 3*(x-2)
y=3x-6+2
y=3x-4
The value of b = -4
Therefore, the equation of the second line is y=3x-4.

When a circle is wholly rotated, the center forms a 360-degree angle.
A complete rotation at the central point of the circle yields 360 degrees.

The mass of a paper clip is 5.0 x 10^−4 mg. If a box of paper clips has 6.85 x 10^4 paper clips, determine the total mass of the paper clips in the box. Write the final answer in scientific notation with the correct number of significant digits.
=====================================================
Explanation:
Multiply the given values. This is because,
total mass = (number of paperclips)*(mass per paperclip)
So,
(5.0 x 10^−4)(6.85 x 10^4)
(5.0 * 6.85) x (10^−4 * 10^4)
34.25 x 10^(-4+4)
34.25 x 10^0
(3.425 x 10^1) x 10^0
3.425 x 10^(1+0)
3.425 x 10^1
3.4 x 10^1
We round the first value to 2 sig figs because it is the smaller sig fig count of 5.0 and 6.85; the 0 in 5.0 is significant.
Notice how I rewrote 34.25 into 3.425 x 10^1. I did this to get the number in the form a x 10^b, where [tex]0 \le a < 10[/tex], which fits scientific notation form.
The value 3.4 x 10^1 simplifies to 34. So an estimate of the total mass is about 34 mg. But we'll stick with scientific notation since your teacher instructed it.

What is an angle in math?
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.The bearing of B from D is angle ADB, which is
∠ADB = arctan(30/45) ≈ 33.7°
The bearing of D from B is that angle plus 180°, so is
180° +33.7° = 213.7°
We use angle ADB because the reference direction for bearings is North.
The tangent of an angle (ADB) is the ratio of its opposite side (AB) to its adjacent side (AD).
