How many intersecting planes are there in a cube?
Answer: a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.
Step-by-step explanation:
Answer:
The cube has nine symmetry planes. Three planes lie parallel to the side squares and go through the centre (picture). Six planes go through opposite edges and two body diagonals. They divide the cube into prisms

three more than five times the number of dogs find the algebraic expression
Answer: 5x+3
Step-by-step explanation: 3 more refers to addition so you are aware that 3 is the number that is being added in the equation, and 5 times refers to multiplication so you know 5 is being multiplied in the equation, which means the algebraic expression would be: 5x+3.
Which function has an inverse that is also a function?
{(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}
{(–4, 6), (–2, 2), (–1, 6), (4, 2), (11, 2)}
{(–4, 5), (–2, 9), (–1, 8), (4, 8), (11, 4)}
{(–4, 4), (–2, –1), (–1, 0), (4, 1), (11, 1)}
Answer:
A. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}
Step-by-step explanation:
I just did the quiz but basically you can switch the coordinates around to view the coordinates of the inverse function. If there are x values that are the same number, it does not pass the line test making it not a function with an inverse function.
The function has an inverse that is also a function will be {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)} so correct option will be (A).
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine may only produce one output for each input and will only accept inputs that are specifically listed as part of the function's domain.
In other words, the function is a relationship between variables and the nature of the relationship.
In the given question
We know that a function is only a function such that there is a unique value of y corresponding to x.
An inverse function will only be a function if the function which is going to be inverse is a function.
In option (A) all value of x corresponding to y are different but in all remaining options the values are repeating hence that will be not a function since only (A) has to inverse

Answer:
x = 2
y = 3
Step-by-step explanation:
x = 3y - 4
5x + 2y = 31 in the second equation replace x with 3y - 4
5 (3y - 4 ) + 2y = 31 multiply 5 with inside the parenthesis
15y - 20 + 2y = 31 add like terms
17y = 51
y = 3
Now, since we found the value of y we can use it to calculate x
x = 3y - 4
x = 3×3 - 4
x = 2

9x10^7 is how many times as large as 3x10^3
9x10^7
10x10=100x10=1,000
1,000x10=10,000
10,000x10=100,000
100,000x10=1,000,000
1,000,000x10=10,000,000
10,000,000x9=90,000,000
3x10^3
10x10=100x10=1,000
1,000x3=3,000
90,000,000/3,000=30,000
So 9x10^7 is 30,000x larger than 3x10^3

9x [tex]10^7[/tex] is 30,000 times larger than 3 x 10³.
What is Exponents?The number of times a number has been multiplied by itself is referred to as an exponent.
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
Given:
9x [tex]10^7[/tex]
The number [tex]10^7[/tex] can be expanded as
[tex]10^7\\[/tex] = 10,000,000
and, 9x [tex]10^7[/tex] = 9 x 10,000,000
= 90,000,000
The number [tex]10^3[/tex] can be expanded as
[tex]10^3[/tex] = 1000
and, 3 x 10³ = 3 x 1000
= 3000
Then, 90,000,000/3,000
=30,000
Hence, 9x [tex]10^7[/tex] is 30,000 times larger than 3 x 10³.

f(k-1) = 5k² - 4k - 4
The given function is:
f(x) = 5x² + 4x - 5
To find f(k-1), substitute x = k-1 into f(x)
f(k-1) = 5(k-1)² + 4(k-1) - 5
f(k-1) = 5(k² - 2k + 1) + 4k - 4 - 5
f(k -1) = 5k² - 10k + 5 + 4k -9²

Answer:
y = - [tex]\frac{63}{4}[/tex] or - 15.75
Step-by-step explanation:
Order of operations.
y + [tex]\frac{9}{2}[/tex] = y - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex] Subtract y from each side.
y - y + [tex]\frac{9}{2}[/tex] = y - y - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex]
[tex]\frac{9}{2}[/tex] = - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex] Add [tex]\frac{3}{4}[/tex] to each side
[tex]\frac{9}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex]
[tex]\frac{9}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex] Find the common denominator for [tex]\frac{9}{2}[/tex] and [tex]\frac{3}{4}[/tex], which is 4
[tex]\frac{9}{2}[/tex] * [tex]\frac{2}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex]
[tex]\frac{18}{4}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex]
[tex]\frac{21}{4}[/tex] = - [tex]\frac{y}{3}[/tex] Multiply each side by 3
[tex]\frac{21}{4}[/tex] * 3 = - [tex]\frac{y}{3}[/tex] * 3
[tex]\frac{63}{4}[/tex] = - y Divide each side by -1
y = - [tex]\frac{63}{4}[/tex] = - 15 [tex]\frac{3}{4}[/tex]

Two numbers have a sum of 2 and a difference
of -16. What are the numbers?
Answer:
-7 & 9
Step-by-step explanation:
(-7) + 9 = 2
(-7) - 9 = -16
x + y = 2
x - y = -16
Add the equations together to eliminate one of the variables.
2x = -14
Divide both sides by 2
x = -7
Let's plug -7 into x for our first equation.
-7 + y = 2
Add 7 to both sides.
y = 9
The highest ever recorded temperature on earth was 136°F in the US and the lowest was − ° 129 F in Antarctica. What is the difference of these temperatures recorded on Earth?
Answer:
136 + 129= 265
Step-by-step explanation:
when you're finding the difference and one number is positive and the other is a negative number you will add the negative instead of add them together so you would 129 to 136 which would equal 265. this rule applies to the opposite too. if both numbers are positive, then you would subtract them.
