Step-by-step explanation:
-8n +19n= -41+4+17
11n = -20
n = - 20/ 11
n= 1.1818
Answer: 
Step-by-step explanation:
This car follows a line, hence its motion can be modeled by the Line equation.
In fact, we already have two points of the line, if we call
the time in hours and
the traveled distance in miles:
Point 1:
Since we are told the car's initial position is 300 miles in the time 0 h
Point 2:
Since we are told the car's final position is 180 miles after 3h

<u>Let's find the Slope
:
</u>
This is the slope of the line
Now, the equation of the line is:
We already know the slope, now we have to find the intersection point with the y-axis (
) with any of the given points. Let's choose Point 1:
Isolating
:
Then, the equation of the line is:
Answer:
l = 11.19 feet
Step-by-step explanation:
Given that,
The width of a roll of gasket material, b= 16 inches
We need to find the length needed to obtain 15 sq ft of the material.
We know that,
1 foot = 12 inches
⇒ 16 inhces = 1.34 feet
For a rectangular shaped object, area is given by :
A = l×b

So, the required length is 11.19 feet.
The function y = - 50x + 75 is linear. So, the correct option is (A).
<h3>Define linear function.</h3>
The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line. Here,
The line has a slope of m and a y-intercept of b.
The independent variable is "x."
The dependent variable is "y" (also known as f(x)).
Consider the equation y = - 50x + 75
Compared to the linear function equation, we get
m = -50
b = 75
So, the function is a linear function with a constant change. The function will be linear at all points.
