City -------- Number of restaurants
Carlsbad 489
Potter Valley 261
Little Heath 282
Edgbaston 216
Barrow 317
If we want to know how many more restaurants there are in Carlsbad than in Barrow, we need to subtract the number of restaurants in Barrow from Carlsbad as follows:
[tex]489-317=172[/tex]From the table, we have that in Carlsbad there are 489 restaurants, while there are 317 in Barrow.

The values for first question are f(x) = x², g(x) = (x - 9) and for second question f(x) = √x, g(x) = 9 + √x.
A function may be defined as an expression in which for one value of input variable x there is only one value of output variable y. The input variable is called independent variable and output variable is called dependent variable. A composite function is the one which is written as a combination of two function. For two given functions f(x) and g(x) the composite functions are f(g(x)) and g(f(x)). In the first question the composite function is F(x) = (x - 9)². the parent functions will be f(x) = x² and g(x) = (x - 9).
in the second question the composite function is H(x) = √(9 + √x). The parent functions will be f(x) = √x and g(x) = 9 + √x.

A number with an absolute value of 42 was divided by a number with an absolute value of 7 The quotient -6. Write two posibble numeric equations
Answers
Answer:
-42/7 and 42/-7
Explanation:
The absolute value of a number is represented by:
[tex]|x|[/tex]The lines represent absolute value of a number x, and what it does is that it makes everything into a positive number.
For example |-5|=5 and |5|=5, so we always have two options with an absolute value: that it comes from a negative number or that it comes from a positive number.
In this case we have that a number with an absolute value of 42 (it could be |-42|=42 or |42|=42) divided by a number with an absolute value of 7 (it could be |-7|=7 or |7|=7) the quotient is -6.
One possible numberic equation is:
[tex]\frac{-42}{7}=-6[/tex]Since this meets all the above conditions
Another possible numeric equation is:
[tex]\frac{42}{-7}=-6[/tex]Since this too meets all the above conditions.

The price that Misu can pay for a comforter based on the markup percentage is $103.57.
How to calculate the value?From the information, the Bedspread shop knows his customers will pay no more than $145 for a comforter Misu wants a 40 percent markup on selling price.
Let the selling price be represented as x. Based on the information given, this will be illustrated as:
x + (40% × x) = 145
x + 0.4x = 145
1.4x = 145

Put the following equation of a line into slope-intercept form, simplifying all fractions.
4x-20y=-160
Answers
The equation of the line 4x-20y = -160 in the slope intercept form is y = x/5 + 8 .
The equation of the line in slope intercept form is written as
y = mx + c ,
where m is the slope of the line , and c is the y intercept .
In the question ,
the equation of the line is given
equation of line is given as 4x-20y = -160
to convert the equation in slope intercept form , we rewrite it as
20y = 4x+160
dividing both sides by 20 ,
we get
20y/20 = 4x/20 + 160/20
y = x/5 + 8
hence ,the slope intercept form is y = x/5 + 8 , where 8 is the y intercept and 1/5 is the slope .
Therefore , the equation of the line 4x-20y = -160 in the slope intercept form is y = x/5 + 8 .

We know that the mean is 80, the median is 90, and the mode is 70. This means that the majority of students got an 80 on the test.
However, the median is 90, which means half of the class is below 90 where Tom's grade is placed.

The ordered pair that describes the location of N is (2,6)
Given:
N's coordinates are: (-2,-6)
Point N ′ is produced by reflecting point N over the y-axis.
By reflecting point N' over the x-axis, the final point N" is produced.
x , y = -x , y
N(-2 -6) = N'(2 6)
To locate the ordered pair describing where N" is located.
Point N's coordinates are (-2,-6). Point N ′ is produced by reflecting point N over the y-axis.
x , y = -x , y

When we have a function and want to evalueate it for some "x", we just substitute every "x" with the value in parenthesis. So, to evaluate f(a + 2), we have x = a + 2, so we need to substitute every "x" in the function with a + 2:
[tex]f(a+2)=(a+2)^2-2(a+2)+1[/tex]Now, to simplify, we first need to use the distributive property on the second parenthesis and evaluate the binomial in the first:

"Difference" is a clue word that tells you to use subtraction. The other clue word is "times" but that means times, or multiplication and is pretty straight forward.
"Three times a number" means to multiply a number, but we don't know the number, so we use a variable (a letter). I put x but you could use n or c or almost any letter for the variable.
"the difference of ___ and ___" means to subtract those two things.

[tex]C(x)=R(x)-P(x)[/tex]which is
[tex]C(x)=0.15x-(0.082x-0.8)[/tex][tex]C(x)=0.15x-0.082x+0.8[/tex][tex]\boxed{C\mleft(x\mright)=0.068x+0.8}[/tex]Part B:
