This year it raised the parking price to $5.00 and parked 850 cars. Did the station owner make a good economic decision in raising the parking prices from one year to the next? Explain.
The station owner make a good economic decision in raising the parking prices from one year to the next Ashe made an extra profit of $250.
How to explain the information?From the information, the gasoline station very near a professional football stadium parks cars on its lot to make money on game days. Last year it charged $4.00 per car and parked 1000 cars. The amount made last year will be:
= Amount charged × Number of cars
= $4 × 10000
= $4000
This year it raised the parking price to $5.00 and parked 850 cars. The amount made will be:
= $5 × 850
= $4250
Therefore, the profit made will be:
= $4250 - $4000

statement is NOT true?
The statement which is not true for the given number line is |c| < d.
What is a number line?The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are written down on a number line, it is straightforward for humans to compare them and perform basic arithmetic operations on them. One might assume that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases. This shows that the numbers on the right are more numerous than those on the left.
When any value is written within the mod, it is always considered a positive value.
So, accordingly option (B) |c| < d is the correct answer.

In other words, a set is a collection of elements or numbers or objects, represented within the curly brackets { }. For example a collections of alphabets {a, b, c, d, e, f, g, h}
Therefore, universal set (usually denoted by U) is a set which has elements of all the related sets, without any repetition of elements.
Hence,

Examples of odd functions are;
The odd functions are; C, D E, H, J, K, N
Find h (-4), h (0), and h (1).
Answer:
The piecewise function is given below as
[tex]h(x)=\begin{cases}\frac{1}{2}x-2,x<-2 \\ (x-1)^2-1.-2\leq x\leq1 \\ 2,x>1\end{cases}[/tex]Step 1:
To figure out h(-4),
The function that satisfies this is given below as
[tex]\begin{gathered} \frac{1}{2}x-2,x<-2 \\ \text{note:} \\ -4<-2 \end{gathered}[/tex]Therefore,
Substitute the value of x=-4
[tex]\begin{gathered} \frac{1}{2}x-2 \\ h(-4)=\frac{1}{2}(-4)-2 \\ h(-4)=-2-2 \\ h(-4)=-4 \end{gathered}[/tex]Hence,
h( -4 ) = -4
Step 2:
To figure out h(0)
The function that satisfies this condition is given below as
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ \text{note:} \\ 0<1 \end{gathered}[/tex]Hence,
Substitue the value of x = 0
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ h(0)=(0-1)^2-1 \\ h(0)=(-1)^2-1 \\ h(0)=1-1 \\ h(0)=0 \end{gathered}[/tex]Hence,
The value for h( 0 ) = 0
Step 3:
To figure out h( 1)
The function that satisfies this condition is given below as
[tex](x-1)^2-1.-2\leq x\leq1[/tex]Substitute x= 1 in the equation below
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ h(1)=(1-1)^2-1 \\ h(1)=0-1 \\ h(1)=-1 \end{gathered}[/tex]Hence,

What is a direct proportional relationship?
In a direct proportional connection, the output variable is determined by multiplying the input variable by the proportionality constant, k, as in the example below:
y = kx.
For the first question, we have that out of a total distance of 8 miles, they:
Walk 3/8 of the distance.
Run 5/8 of the distance.
Hence the proportional relationships for the distances are given as follows:
Walked = 3/8 x Total Distance.
Ran = 5/8 x Total Distance.
For a total distance of 32 miles, the distances walked and ran are given as follows:
Walked: 3/8 x 32 = 3 x 4 = 12 miles = 12 laps.
Ran: 5/8 x 32 = 5 x 4 = 20 miles = 20 laps.
For the second question, we have that the table has to following the given ratios of the first row to the second row, with the third row being the sum of the first two rows, hence the third table is correct.

We need to find the set that has the subset E.
Explanation:
Recall that a set A is a subset of another set B if all elements of set A are elements of set B.Consider the set A = {1, 2, 4, 7, 10, 11, 9, 6}.
Element 6 from E is not an element of A.

The symbol that looks like an inverted U means interception. The interception of B and C is given by al the elements that B and C share. In order to find it we simply need to writte B and C and find the numbers that are part of both:
[tex]\begin{gathered} B=\mleft\lbrace1,2,3,4\mright\rbrace \\ C=\mleft\lbrace5,6,9\mright\rbrace \end{gathered}[/tex]As you can see there is no nuber that belongs simultaneously to both B and C. This means that the intersection between B and C is an empty set and is represented with the following symbol:

What is the Absolute Value ?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
Since the absolute value is isolated, we set it equal to the positive and negative of the constant
Therefore,
|(-x+2)| =
for x < 2, -(-x + 2)
for x ≥ 2, (x + 2)
Hence, This is so that no matter the value of x, the value of the function is always greater or equal to 0.
