what is the constant rate of change of y=7-13x
The constant rate of change in the linear equation y=7-13x is -13, representing the slope of the line which remains constant for any value of x. This is different from nonlinear functions, where the rate can vary with x.
Explanation:The constant rate of change in the equation y=7-13x refers to the slope of the line represented by this linear equation. In this case, the constant rate of change, or the slope, is -13. This means for every one unit increase in x, y decreases by 13 units. Since the equation is linear, this rate does not change regardless of the value of x, unlike in nonlinear functions where the rate of change can vary with x.
To elaborate, if we have a nonlinear function, the rate of change depends on the interval of x we are looking at. For a linear function like this one, the slope is the same over any interval, so there's no need to compute it over smaller ranges of x to understand the rate of change.
Moreover, in calculus, the derivative represents the rate of change, and for a linear function, the derivative is simply the coefficient of x. Hence, the derivative of y with respect to x is -13. The derivative is zero for any constant term in a function, such as the 7 in the given equation.

Jana is on a two-day hike. The function graphed shows the total distance she hiked, in miles, after x hours on the second day.
Select from the drop-down menus to correctly identify the information about Jana's hike provided by the graph.
Answer:
The slope is 2.
Step-by-step explanation:
The function graphed shows the total distance she hiked, in miles, after x hours on the second day.
Seeing at the graph, we have the following points.
(2,8) , (3,10) , (4,12)
For slope we will do the following.
[tex]\frac{10-8}{3-2} =\frac{2}{1}[/tex] = 2
[tex]\frac{12-10}{4-3} =\frac{2}{1}[/tex] = 2
So, the slope is 2.
The slope represents that 2 miles is hiked in each hour.

Marc earned $1,650 per month as an assistant technician at a recording studio. His new job pays $9.80 per hour with time and a half for all hours over 36 hours per week. How many hours of overtime per week will he need to work to earn the same amount per week as his current job?
Marc will need to work just over 4 hours of overtime each week at his new job, which pays $9.80 per hour and $14.70 per hour for overtime, to earn the equivalent of his previous monthly income of $1,650.
To determine the number of overtime hours Marc needs to work at his new job to earn the same monthly income he did at his previous job, we'll first calculate his weekly income at his old job, then use the overtime pay rates at the new job to find the equivalent number of hours needed.
Marc previously earned $1,650 per month. Assuming a standard 4-week month, his weekly income was:
$1,650 per month / 4 weeks per month = $412.50 per week.
At his new job, Marc earns $9.80 per hour with time and a half for all hours over 36 hours a week. This means his overtime pay is 1.5 times his hourly rate, which is:
$9.80 per hour x 1.5 = $14.70 per hour for overtime.
Marc's income for the first 36 hours at his new job would be:
36 hours x $9.80 per hour = $352.80
To earn the equivalent of his old weekly salary, we must make up the difference with overtime pay:
$412.50 (old weekly income) - $352.80 (new regular pay) = $59.70 needed from overtime.
To determine the overtime hours needed to make $59.70: $59.70 / $14.70 per hour = approximately 4.06 hours.
Therefore, Marc will need to work just over 4 hours of overtime each week to earn the same amount he did at his previous job.

A cheetah can run 103 feet per second. A zebra can run x feet per second. Use the Distributive Property to write and simplify an expression for how much farther the cheetah can run in 10 seconds
We are given that the rate of cheetah Rc is:
Rc = 103 ft / sec
And the rate of zebra Rz is:
Rz = x ft / sec
We are to find the distance between the two after 10 seconds, that is:
distance = (103 – x) 10
distance = 1030 – 10 x
The expression for how much farther a cheetah can run than a zebra in 10 seconds, given that the zebra's speed is x feet/second, is 1030 - 10x feet.
Explanation:To find out how much farther the cheetah can run in 10 seconds, we need to determine the difference between the cheetah's speed and the zebra's speed, and then multiply by time.
Firstly, the cheetah's speed is 103 feet per second. Let x denote the zebra's speed. The difference in speed is expressed as (103 - x) feet per second.
To find out how much farther the cheetah runs in a given time, we multiply the difference in speed by time. Therefore, the expression for how much farther the cheetah can run in 10 seconds is 10 * (103 - x), which simplifies to 1030 - 10x feet.

Which inequality's solution is graphed here?
A) x + 9 < 5
B) x - 5 < 9
C) x + 5 < 9
D) x - 9 < 5
Answer:
there is an open dot on 4.....an open dot means there is no equal sign in the problem....and it is shaded to the left...means it is less then. So ur looking for an inequality with the answer being x < 4.
x + 5 < 9 <== its gonna be this one
x < 9 - 5
x < 4

which equation best represents the line graphed above
a x=4
b x= _ 4
y= x -4
y= - 4
The correct answer is option B. The equation best represents the line graphed is x = -4.
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Since x = -4 is a vertical line(perpendicular to horizontal), there is no y-intercept and the slope is undefined.
A vertical line has an undefined slope because all points on the line have the same x-coordinate.
So, the slope is undefined and we also don't have the y-intercept.
