N × (-5/6) ≥ -1/2 is the inequality for the statement
How to write an inequality for the statement?
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g 5 < 6, x ≥ 2, etc.
Given the statement: negative one half is a minimum of the product of a number and negative five sixths.
This statement can also be written as the product of a number and negative five sixths is greater than or equal to negative one half
Let N represent the number. Thus, the inequality of the statement is:
N × (-5/6) ≥ -1/2
Note: The symbol ≥ is pronounced as greater than or equal to
Therefore, the inequality for the statement is N × (-5/6) ≥ -1/2

Write the equation of the line in fully simplified slope-intercept form.
Answer: y = -x - 8
Step-by-step explanation:
Slope-intercept form is given in y = mx + b where m is the slope and b is the y-intercept.
We can see our b, the y-intercept, is -8 since the line intercepts the y-axis at (0, -8).
For our slope, we can see that the line moves down one and right one for a slope of 1/1=1. Since it's moving downwards, the slope is -1.
Now, we will write the full equation:
y = -x - 8

The product doubles when one of the factors in a multiplication problem is doubled
What is a product?A product in mathematics is the result of multiplication, or an expression that identifies the objects to be multiplied, known as factors. For instance, 30 is the sum of 6 and 5.
In mathematics, multiplying means adding equal groups. The number of things in the group grows as we multiply. A multiplication problem includes the two factors and the product.
For example, 2 × 3 = 6. When 2 is doubled, it becomes 4 and the product will be:
= 4 × 3 = 12

Write an equation for line L in point-slope form and slope-intercept form?
L is perpendicular to y=5x
Write an equation for the line L in point - slope form
The linear equation in the slope-intercept is:
y = (-1/5)*x - 26/5
And it can be written as:
y = (-1/5)*(x + 1) - 5
How to find the equation for line L?
We can write the equation for line L as:
y = a*x +b
Where a is the slope and b is the y-intercept.
Two lines are perpendicular if the product between the slopes is equal to -1.
So if we want our line to be perpendicular to y= 5x, then we must have:
a*5 = -1
a = -1/5
So our line is something like:
y = (-1/5)*x + b
And the line passes through (-1, -5), replacing these values:
-5 = (-1/5)*-1 + b
-5 = 1/5 + b
-5 - 1/5 = b
-26/5 = b

The equation a = 12850 + 530h gives a hiker's altitude a (in feet), h hours after beginning his hike.
A. At what rate, in feet per hour, is the hiker gaining altitude?
The rate of gaining altitude for the hiker is 530 feet per hour.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as g'(x) = (g(x + h) - g(x)) /(x + h - x).
Its geometric aspect is the slope of the function at a given point.
The given equation for hiker's altitude is as below,
a = 12850 + 530h
Here a is the altitude in feet and h is time in hours.
In order to find the rate of gaining altitude, the equation for altitude has to be differentiated with respect to hours as below,
a = 12850 + 530h
Differentiate the above equation w.r.t h as,
da/dh = 0 + 530

As a result, when one quantity changes, the other follows suit, increasing when the first changes and decreasing when the first changes. To put it another way, two quantities are said to be directly proportional to one another if the ratio of the first to the second is a constant term. The coefficient or constant of proportionality is the name given to this constant quantity.The mathematical relationship between the two quantities in the direct variation formula makes it so that one of the variables is a constant multiple of the other.
