Answer:
B
Step-by-step explanation:
The profit made is equal to 2.25-2.25 which is 0.
The situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero. which is the correct answer would be an option (B).
What is the distance?Distance is defined as the product of speed and time.
As per option (A),
The overall change in temperature = 10 - (-10) = 20 degrees
As per option (B),
The profit made is equal to 2.25 - 2.25 = 0 which is zero.
As per option (C),
The overall change in altitude = 21 - 0 = 21 kilometers
As per option (D),
The total distance traveled by person = 3.1 + 3.1 = 6.2 miles
Thus, the situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero.
Hence, the correct answer would be option (B).

A bowl contains a total of 26 blue and red marbles. There are two more red marbles than
blue marbles. How many blue marbles are in the bowl?
Which of the following let statements should you use?
Let x = the number of red marbles. Let x + 2 = the number
of blue marbles.
Let x = the number of blue marbles. Let 2x = the number of
red marbles.
Let x = the number of blue marbles. Let x + 2 = the number
of red marbles.
Answer:
There are 26 total marbles. We will call x the number of blue
marbles. So there are x+2 red marbles. If you add them together you
get x + x + 2....and all that equals 26 (subtract 2 from each side

Answer:
wrong its actually D. x=7, y=1
i just took the test
The solution of the equation is x=7 and y=1, option D is correct
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are 3x - 5y = 16 and 2x - 7y= 7
we have to solve the equations
6x-10y=32...(1)
6x-21y=21...(2)
6x-10y-6x+21y=32-21
11y=11
Divide both sides by 11
y=1
Now plug in y value in any of equation to get x
3x-5=16
3x=16+5
3x=21
x=7
Hence, the solution of the equation is x=7 and y=1, option D is correct

Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answer:
The graph of the function passes through the point (100; 113).
Step-by-step explanation:
In order to calculate if the graph of the function passes through the point or not, we need to insert the point's coordinates in the function and check if the equation is valid or not, if it is, then the graph passes through them.
[tex]y(x) = 1.2*x - 7\\y(100) = 1.2*100 - 7\\y(100) = 120 - 7 \\y(100) = 113[/tex]
Which is equal to the "y" coordinate of the point, therefore the graph of the function passes through the point (100;113).

If the probability of turning left is 0.5 and the probability of
turning right is 0.5 for each mouse, what is the probability that ONLY ONE
of the two mice will turn left? *
Answer:
0.5
Step-by-step explanation:
The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.
The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.
So the probability that only one mouse turns left is:
P = 0.25 + 0.25
P = 0.5
Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.
P = 1 − (P(both left) + P(both right))
P = 1 − (0.5 × 0.5 + 0.5 × 0.5)
P = 0.5
Is area the same as surface area?
Answer:
Area is almost the same as surface area. However, surface area is more complicated, and you have to split the object that you are measuring into different parts to get their area before you can find the whole surface area.
Step-by-step explanation:
(I hope this helped you)
Answer: No, it is not
Step-by-step explanation:
AREA DEFINITION: Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width.
SURFACE AREA DEFINITION: The surface area is the sum of the areas of all six sides. To find the area of adjacent sides (Width x Height) x 2 sides. Find the area of ends (Length x Width) x 2 ends. Add the three areas together to find the surface area.

Find a polynomial function with the zeros -2, 3, 5 whose graph passes through the point (6,48)
Answer:
f(x) = 2x³ - 12x² - 2x + 60
Step-by-step explanation:
Given that the zeros are x = - 2, x = 3, x = 5 , then the factors are
(x + 2), (x - 3), (x - 5)
The polynomial is then the product of the factors, that is
f(x) = a(x + 2)(x - 3)(x - 5) ← a is a multiplier
To find a substitute (6, 48) into the polynomial
48 = a(8)(3)(1) = 24a ( divide both sides by 24 )
a = 2 , thus
f(x) = 2(x + 2)(x - 3)(x - 5) ← expand the last 2 factors using FOIL
= 2(x + 2)(x² - 8x + 15) ← distribute the parenthesis
= 2(x³ - 8x² + 15x + 2x² - 16x + 30)
= 2(x³ - 6x² - x + 30) ← distribute by 2
= 2x³ - 12x² - 2x + 60
Using the factor theorem, it is found that the polynomial function is given by:
[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]
-----------------------------
Factor theorem:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
-----------------------------
Zeros of -2, 3 and 5 mean that [tex]x_1 = -2, x_2 = 3, x_3 = 5[/tex]The polynomial is given by:
[tex]p(x) = a(x - x_1)(x - x_2)(x-x_3)[/tex]
[tex]p(x) = a(x - (-2))(x - 3)(x - 5)[/tex]
[tex]p(x) = a(x + 2)(x - 3)(x - 5)[/tex]
[tex]p(x) = a(x^2 - x - 6)(x - 5)[/tex]
[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]
-----------------------------
It passes through the point (6,48), thus when [tex]x = 6, p(x) = 48[/tex].This is used to find the leading coefficient.[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]
[tex]48 = a(6^3 - 6(6)^2 - (6) + 30)[/tex]
[tex]24a = 48[/tex]
[tex]a = \frac{48}{24}[/tex]
[tex]a = 2[/tex]
Thus, the polynomial is given by:
[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

The product of two rational numbers is ______ rational.
The product of two rational numbers is always rational
Proof:
Let a = p/q and b = r/s be two rational numbers. We will have p,q,r,s be integers where denominators q and s are nonzero. We cannot divide by zero.
Multiplying a and b gives
a*b = (p/q)*(r/s) = (p*r)/(q*s)
Due to the closure property of integer multiplication, the expressions p*r and q*s are integers. The result we get is in the form of integer/integer. Basically we have two integers being divided. Furthermore, q*s is nonzero as neither q nor s is zero.
Therefore, if a and b are rational, then a*b is also rational as well.

-7+ 5Y = -37 simplify your answer as much as possible
Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5
y = -6

The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.
How do you find the critical points of an inequality?Solve a rational inequality.
Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.
How do you find the critical points of a function?To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.
