The solution set of the inequality for R is given by [tex]-\frac{1172}{85} \leq x\leq \frac{1228}{55}[/tex] .
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. It is frequently used to compare two numbers on the number line based on their sizes. Different types of inequalities are represented by a variety of notations such as < ,> ,≤ and ≥.
The modulus function takes the absolute value of a function.
To solve the given inequality we have simplify the inequality first.
[tex]x-\frac{7}{9} |(\frac{12}{5} -6x)|+50\ge -30[/tex]
[tex]or, x-\frac{7}{9}\times \frac{6}{5} |(2-5x)|+50\ge -30\\or,x-\frac{14}{15}|2-5x|\ge-80\\[/tex]
Now we separate the inequalities:
[tex]x-\frac{14}{15}(2-5x)\ge-80[/tex] for 2x-5 ≥ 0
[tex]x-\frac{14}{15}(-(2-5x))\ge-80[/tex] for 2x-5 ≤ 0
Now we will solve the two inequalities separate and find the intersection.
[tex]x-\frac{14}{15}(2-5x)\ge-80\\or,15x-28+70x\ge-1200\\or,x\ge -\frac{1172}{85}[/tex]
Again
2x-5 ≥ 0
or, [tex]x\le\frac{2}{5}[/tex]
hence [tex]-\frac{1172}{85}\le x\le\frac{2}{5}[/tex]
Similarly solving the other inequality we get
[tex]\frac{2}{5}\le x\le\frac{1228}{55}[/tex]
Now we find the intersection of the two inequalities:
[tex]-\frac{1172}{85}\le x\le\frac{1228}{55}[/tex]

The area of the polygon is approximately 24.497 square units.
How to determine the area of a polygon
In accordance with the statement, we have a polygon with three vertices set on Cartesian plane, that is, a triangle. We need to find the side lengths first and later to calculate the area by Heron's formula. First, determine the lengths of each line segment by Pythagorean theorem:
JK = √[[4 - (- 3)]² + (4 - 4)²]
JK = 7
KL = √[(3 - 4)² + (- 3 - 4)²]
KL = √[(- 1)² + (- 7)²]
KL = 5√2
JL = √[[3 - (- 3)]² + (- 3 - 4)²]
JL = √85
Second, calculate the area of the triangle:
s = (JK + KL + JL) / 2
s = (7 + 5√2 + √85) / 2
s ≈ 11.645
A = √[s · (s - JK) · (s - KL) · (s - JL)]
A = √[11.645 · (11.645 - 7) · (11.645 - 5√2) · (11.645 - √85)]
A ≈ 24.497
The area of the polygon is approximately 24.497 square units.

to know the angle of depression of the meat from the top of the table

Tan is the ratio of perpendicular and base of the triangle

Answers
The value of the functions f(6), f(- 10), f(0) are 9, 7 and 3 respectively.
What is a function?A function can be defined as an expression, rule or law that shows the relationship between a dependent and an independent variable.
Given the function;
f(x) = |x+3|
To determine f(6)
Substitute the value of x as 6
We have;
f(6) = | 6 + 3 |
f(6) = 9
To determine f(-10)
Substitute the value of x as - 10
We have;
f(-10) = | -10 + 3 |
f(-10) = | -7|
f(-10) = 7
To determine f(0)
Substitute the value of x as 0
We have;
f(0) = | 0 + 3|
f(0) = 3
Thus, the value of the functions f(6), f(- 10), f(0) are 9, 7 and 3 respectively.

The vehicle will get speed of approximately 15 mph and -210 mph.
What is speed?Science's most important concept is measurement. Many measurable quantities are measured in fundamental or base units. One such measurable quantity is speed, which is defined as the ratio of an object's distance travelled to the time required to travel that distance. Let us learn about speed in depth during this session.
The ratio of distance to time taken to cover a distance is used to calculate speed. Because it only has one direction and no magnitude, speed is a scalar quantity.
Given the equation for gas mileage = 0.02x² + 3.9x - 43 where x means speed
We have been asked to find x if gas mileage = 20 that is
0.02x² + 3.9x - 43 = 20
Lets simplify
⇒ 0.02x² + 3.9x - 43 = 20
⇒ x² /50 + 39x/10 - 63 = 0
⇒ x²/ 50 + 195x/50 - 3150 = 0
⇒ 1/50 (x + 195x - 3150 ) = 0
⇒ 1/50 (x + 210x - 15 x - 3150 ) = 0
⇒ 1/50 (x (x+210) −15 (x+210)) = 0
⇒ 1/50 (x−15)(x+210) = 0
⇒ (x−15)(x+210) = 0 × 50
⇒ (x − 15)(x + 210) = 0
⇒ x = 15, x = -210
So, try using 15 mph and -210 mph, that might work.

This is an arithmetic sequence
The nth term of an arithmetic sequence is Tn = a + (n-1)d
a is the first term.
n is the number of terms
d is the common difference
Given that 19th term of the sequence is:
gn=gn−1⋅(−12) if g17=162
Suppose a=12
Then,
The 17th term g17=a+(n-1)d
= 12+(17-1)d
'n' means number of terms
12+(17-1)d=162 because g17=162
12+16d=162
16d=162-12
Subtract the values,
We can write,
16d=150
d=150/16
Divide the values,
We can write,
d=25
To get the sixth term g6
g6=12+(6-1)d

As per the question statement, we are supposed to find the time taken by the car to drive to the next stop which is 16 miles away if it is driving on the interstate with cruise control on at a constant speed of 64 miles per hour.
Before solving the question, we need to know the concept of relation between time, distance and speed, which states that
[tex]speed=\frac{distance}{time}[/tex]
In the question [tex]speed = 64 mph\\distance = 16 miles\\time taken = t[/tex]
