Could a polyhedron have 10 faces, 3 vertices and 11 edges
Answer:
Yes, it can.
Step-by-step explanation:
Possibility of this bring a polyhedron can be proved by Euler's formula, i.e
F+V-E=2
F=10 V=3 E=11
=10+3-11
Essentially, it is 13 - 11, which is 2.
2 = 2, so yes, this does work.

When comparing the f(x) = x2 – x and g(x) = log(2x + 1), on which interval are both functions positive?
(–∞, 0)
(0, 1)
(1, ∞)
(∞, ∞)
Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.
What is the domain and range of a function?The domain is the set of values for which the given function is defined.
The range is the set of all values which the given function can output.
When comparing the f(x) = x² – x and g(x) = log(2x + 1).
For f(x), we have
f(x) = x² – x
f(x) = x² – x + 1/4 - 1/4
f(x) = (x - 1/2)² - 1/4
The domain and the range of the function f(x) will be (-∞, ∞) and (-5, ∞).
For g(x), we have
g(x) = log(2x + 1)
The domain and the range of the function g(x) will be (-1/2, ∞) and (-∞, ∞).
Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.

How do I graph this?Y=4x+1 and Y=x-2? My teacher said that they have to cross each other
This is called system of equations because you are searching a pair of numbers that inserted as x and y verify both equations at the same time.
To solve a system of equation you have to use one equation to express one variable as a function of the other, and substitute the result in the second equation.
In your case you have
y = x - 2
So your y variable will be always equal to x - 2 , even in the second equation. Then we can write
x - 2 = 4x + 1
Here I replaced the "value" of y in the second equation.
Now you have an equation in one variable that you can solve as usual
x - 2 = 4x + 1
4x - x = - 2 - 1
3x = -3
x = -1
With a value for x you can substitute in one of the two equations and obtain y. Because both equations has to be valid at the same time, both equations must give you the same number for y. Let's try:
y = x - 2
y = - 1 - 2
y = -3
and, with the second equation
y = 4x + 1
y = 4 ( - 1 ) + 1
y = - 4 + 1
y = -3
It works! Then our solution is given by x = -1 and y = -3.
To graph this, simply plot these coordinates.

Mr. Porter’s grocery bill is $143.74. If 5.3% sales tax is added to his bill, what is the total Mr. Porter owes?
A:7 dollars and 62 cents
B:149 dollars and 4 cents
C:136 dollars and 12 cents
D:151 dollars and 36 cents
Answer:
D
Step-by-step explanation:
100% = $143.74
1% = 100%/100 = 143.74/100 = $1.4374
5.3% = 1%×5.3 = 1.4374 × 5.3 = $7.61822
$143.74 + 5.3% = $143.74 + $7.61822
or
105.3% of $143.74 = 143.74 × 1.053 = 151.35822 ≈
≈ $151.36

X-4

Answer: If you meant (x^2 + 5x - 36)/(x^2-16) then the answer is: (x+9)/(x-4)
Step-by-step explanation:
This is just factoring, you can use guess and check.
If you take just the numerator: x^2+5x-36 and factor. To factor consider -36, and the multiples that can add up to 5 (from 5x).
x^2 + 5x - 36/(x^2-16)
The denominator is actually a rule of (a+b)(a-b) which in this case (x+4)(x-4)
(x+9)(x-4)/(x-4)(x+4)
Now just divide like terms which is the (x-4)/(x-4)=1
(x+9)/(x+4)
Dylan is going to the fair and has $35. He is going to use $5 for food. The admission is $7, and rides are $1.85 each.
Which of the following equations could you use to find how many rides Dylan can go on?
$12 = $35 + $1.85 x
$35 = $1.85 + $12 x
$1.85 x = $47
$35 = $12 + $1.85 x
Answer:
$35 = $12 + $1.85x
Step-by-step explanation:
the total is 35 so it is alone on the left side of the equal sign
then 5 + 7 is 12 and he has to spend $12
rides are 1.85 each so there is a x next to it
what does PEMDAS mean in math
Hey there!
PEMDAS simply means (the OVERALL question answer)
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
Here’s an example
24 - 4^2 + 2 * 4
= 24 - 16 + 2 * 4
= 24 - 16 + 8
= 8 + 8
= 16
Thus, the answer for that equation is: 16
Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

PEMDAS is the order that you solve a problem.
PEMDAS stands for:
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
If you have an equation or expression that you need to solve, you solve it in this order. You do the parenthesis first, then you solve the exponents, then you do the multiplication and division from left to right, and last you do addition and subtraction from left to right.
In the equation
2 + 3 * 5,
first you would do 3 * 5 because multiplication is before addition.
2 + 15
Then you would do the addition to get the answer:
17.

Ron used a combination of 45-cent stamps and 1-cent stamps to mail a package. He used 15 stamps in all. If the total cost for postage was $4.55, how many 1-cent stamps did he use?
Answer:
Then the count of 1 cent stamps is 15 −x. So for total cost we have. [45x + 1(15 − x)]cents = $4.55. but there are 100 cents in 1 dollar so we change the above to. [45x +1(15 −x)] 100 = 4.55. Multiply both sides by 100. 45x + 15− x = 455. 44x = 440.

Question:
In three days Tina sold 15 boxes. On the second day, she sold 1 more than on the first. On the third day, she sold 5 more than on the first. How many boxes did she sell on the third day?
Answer:
8. Tina sold eight boxes on the third day.
Step-by-step explanation:
Three days, 15 boxes.
On the first day, Tina sold 3 boxes.
On the second, she sold one more than on the first. (4)
On the third day, she sold five more than on the first. (8)
3 + 4 = 7
7 + 8 = 15
So your answer would be:
Tina sold eight boxes on the third day.
Which of the following expressions are equivalent to - -8/-4
a. -8-/4
b. 2
c. none of the above
Hey there!
-8/-4
= 8/4
= -8 ÷ -4
= 8 ÷ 4
= 2
Therefore, your answer is:
Option B. 2
