The sum of 4 times a number and - 7, added to 9 times the number
Answer:
13x – 7
Step-by-step explanation:
If "a number represents x", then:
The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.
(4x + -7) + 9x →
(4x + 9x) + -7 →
(13x) + -7 →
(13x) – 7 →
13x – 7.
The unknown number will be equal to 4.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the sum of 4 times a number and - 7, added to 9 times the number is 45. The value of the unknown number will be calculated as below:-
The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.
(4x + -7) + 9x = 45
(4x + 9x) + -7 = 45
(13x) + -7 = 45
(13x) – 7 = 45
13x – 7 = 45
13x = 45 + 7
13x = 52
x = 4
Therefore, the unknown number will be equal to 4.
The complete question is given below:-
The sum of 4 times a number and - 7, added to 9 times the number is 45. Calculate the value of an unknown number.

Answer:
k = 3
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
__
Using these rules, we can simplify the left-side expression, then equate exponents of the same base.

Which expression is equivalent to 7 2/3 ⋅ 7 1/4?
Answer:
B
Step-by-step explanation:
Recall that [tex]7^a\cdot 7^b = 7^{a+b}[/tex]
So now
[tex]7^{2/3} \cdot 7^{1/3}\\= 7^{\frac{2}{3}+\frac{1}{4}}\\=7^{\frac{8}{12}+\frac{3}{12}}\\=7^{11/12}[/tex]
The equivalent value of the expression is A = 7^ ( 11/12 )
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Let the first number be p = 7 ^ ( 2/3 )
Let the second number be q = 7 ^ ( 1/4 )
And , A = pq
On simplifying , we get
A = 7 ^ ( 2/3 ) . 7 ^ ( 1/4 )
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
So , A = 7 ^ ( 2/3 + 1/4 )
A = 7 ^ ( 11/12 )
Hence , the equation is 7^ ( 11/12 )

The equation to represent the given phrase is 2p-4=-12.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given phrase is "Negative twelve is four less than twice a number, p."
Here, four less than twice a number, p is
2p-4
The difference is equal to -12.
Now, 2p-4=-12
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose -4 to the other side of an equation, we get

Answer and Step-by-step explanation:
This graph is a One to One Function.
For a function to be one-to-one, each x value must have its own y-value, which is the case for this graph.
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If you draw a vertical line on the graph, and it intersects more than once, then the graph does not define as a function because that x value has more than one output (y).

Given the list of numbers, 3, 2, 6, 3, 9, 5, 12, 7, if the pattern continues, what is the sum of the ninth and tenth numbers?
Answer:
Step-by-step explanation:
Every other one beginning with the first 3 adds 3 to the preceding number that has an odd position.
So the odd positions go up 3 6 9 12
And the next odd position is 15 which is the nineth term.
It's hard to tell what the even ones are doing. It could be anything just about. I'm guessing its a 9. So the tenth term is 9.
The sum of 9 and 15 = 24

-x - 2x > 14 + 10
-3x > 24
Answer: A
Hey there! Here's your answer:
The missing steps are : -3x > 24
Here's why:
The inequality is: -x - 10 > 14 + 2x
Now, we need to find the solution of the given inequality:
= x - 10 > 14 + 2x
Subtracting 2x from both the sides:
= -x - 10 - 2x > 14 + 2x - 2x
= -3x - 10 > 14
Adding 10 on both the sides:
= -3x - 10 + 10 > 14 + 10
= -3x > 24
Now, dividing both the sides by -3:
= x < -8
Therefore, the missing steps are: -3x > 24

Step-by-step explanation:
x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.
First part:
x = -2
x + 2y = 1
-2 + 2y = 1
2y = 3
y = 3/2
Second part:
x = 0
x + 2y = 1
0 + 2y = 1
2y = 1
y = 1/2
Third part:
x = 3
x + 2y = 1
3 + 2y = 1
2y = -2
y = -2/2
y = - 1
