Answer:
En la última fila de la zona general hay 98 asientos y en la zona preferencial hay 564 asientos.
Explicación paso a paso:
= 1 + − 1 ×
40 = 20 + 40 − 1 × 2
40 = 20 + 39 × 2
40 = 20 + 78
40 = 98
= (1 + ) 2 ×
12= (36 + 58) 2 ×12
12 = 47 × 12
12 = 564

Is z=4x+9y literal or not
Answers
Answer:
no it is not literal
Step-by-step explanation:
because no matter what you do you will just get whats in the picture sorry it wouldnt let me type it
The equation z = 4x + 9y is a literal equation because the literal equation is an equation that contains more than one variable.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
z = 4x + 9y
As we know, the literal equation is an equation that contains more than one variable.
In the equation z = 4x + 9y there are three variables then it is literal.
Thus, the equation z = 4x + 9y is a literal equation because the literal equation is an equation that contains more than one variable.

The base of a triangular prism is a right triangle with a base of 5 inches and a height of 12 inches. The height of the prism is 21 inches. Whats volume of the prism?
Answers
Answer:
630 cubic inches of 630 in³
Step-by-step explanation:
The formula for the volume of a triangular prism = (Area of the base) × Height of the triangular prism
Area of the base = 1/2 × base × height
= 1/2 × 5 inches × 12 inches
= 30 square inches
Volume of the Triangular prism = Area of the base × Height of the Triangular Prism =
Height of the triangular prism = 21 inches
Volume of the Triangular Prism = 30 Square inches × 21 inches
= 630 cubic inches of 630 in³

Answer:
-11.6
Step-by-step explanation:
First you multiply 3.8 to -2. You will get -7.6, then you add -4. When adding a negative and another negative it is like normal addition but with negative sign. As a result, -7.6 plus -4 is -11.6.

Sydni has 2 fractions and she is confused about how to find a common denominator. The fractions are 2/3 and 3/5. Explain how you would tell Sydni how to determine the least common denominator.
Answers
Answer:
By finding the least common multiples of the denominators of the two fractions
Which is 15
Step-by-step explanation:
Fraction A = 2/3
Fraction B = 3/5
To find the least common denominator of the two fractions,
Fraction A = 2/3 and Fraction B = 3/5, Sydni will have to find the least common multiples of denominator 3 and denominator 5.
Multiples of denominator 3 = 6, 9, 12, 15, 18, 21
Multiples of denominator 5 = 10, 15, 20, 25
The least common multiples of the two denominators is 15
Therefore, the common denominator of Fraction A = 2/3 and Fraction B = 3/5 is 15
Jim was given three functions and asked to determine ƒ + (g ○ h). The functions were ƒ (x) = x2, g(x) = 3x + 1, and h(x) = 2x. Jim started by writing the problem as (ƒ + (g ○ h))(x) = x2 + 2(3x + 1). What was Jim's mistake? What is the correct solution? A. Jim omitted the x in h(x); (ƒ + (g ○ h)) = 7x2 + 2x. B. Jim should have added ƒ and g first; (ƒ + (g ○ h)) = 4x2 + 6x + 1. C. Jim incorrectly performed h ○ g instead of g ○ h; (ƒ + (g ○ h)) = x2 + 6x + 1. D. Jim did not follow the order of operations; (ƒ + (g ○ h)) = x2 + 6x + 2.

The graph of $f(x)$ is shown below.
For each point $(a,b)$ on the graph of $y = f(x),$ the point $\left( 3a - 1, \frac{b}{2} \right)$ is plotted to form the graph of another function $y = g(x).$ For example, $(0,2)$ lies on the graph of $y = f(x),$ so $(3 \cdot 0 - 1, 2/2) = (-1,1)$ lies on the graph of $y = g(x).$
(a) Plot the graph of $y = g(x).$ Include the diagram in your solution.
(b) Express $g(x)$ in terms of $f(x).$

Create a table whose y-values are the square of the x-values.
Answers
Answer:
To create this table, first, you must find the values of x that you want to use, in this case, i will use the set:
{1, 2, 3, 4, 5, 6}
Now, first make a table as:
[tex]\left[\begin{array}{ccc}x&y\\1&\\2&\\3&\\4&\\5&\\6&\end{array}\right][/tex]
Now we need to complete the values of y.
we know that y(x) = x^2
then when we have x = 1, y(1) = 1^2 = 1.
when x = 2, y(2) = 2^2 = 4.
and so on, you input the values of x in the function y = f(x) = x^2
and the values of y are recorded in the table.
f(1) = 1^2 = 1
f(2) = 2^2 = 4
f(3) = 3^2 = 9
f(4) = 4^2 = 16
f(5) = 5^2 = 25
f(6) = 6^= 36
Then the completed table is:

help me with question, i have tried and its very tough.
Answers
Answer:
the value is -5 and the root is 4
Step-by-step explanation:
3x² + kx − 28 = 0
(a) One of the roots is -2⅓ = -7/3. So the value of k is:
3(-7/3)² + k(-7/3) − 28 = 0
49/3 − 7/3 k − 28 = 0
49/3 − 28 = 7/3 k
49 − 84 = 7k
k = -5
(b) 3x² − 5x − 28 = 0
(3x + 7) (x − 4) = 0
x = -7/3 or 4

Larry McCoy desposited three checks to his checking account he remembers that one of the checks was twice the amount of the smallest checks and the largest checks was equal in amount of the sum of the other two if Larry revived 50 cash in cash and had a total deposit of 355,what was the amount of each of three checks?plesae it’s urgent ?
Answers
$67.50
Step-by-step explanation:
The amount of each of three checks is 67.5, 135 and 202.5 respectively
Given:
let
amount of smallest check = c
Amount of larger check = 2 × c
= 2c
Amount of largest check = (c + 2c)
= 3c
Amount revived = 50
Total deposit = 355
Total amount in the account = amount of smallest check + Amount of larger check + Amount of largest check
50 + 355 = c + 2c + 3x
405 = 6c
c = 405 ÷ 6
c = 67.5
Therefore,
amount of smallest check = c
= 67.5
Amount of larger check = 2 × c
= 2c
= 2(67.5)
= 135
Amount of largest check = (c + 2c)
= 3c
= 3(67.5)
= 202.5

Answers
Answer:
-13=x
Step-by-step explanation:
4(-13)-10=-42
-52-10=-42
Answer:Simplifying
4x + -10 = 42
Reorder the terms:
-10 + 4x = 42
Solving
-10 + 4x = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 4x = 42 + 10
Combine like terms: -10 + 10 = 0
0 + 4x = 42 + 10
4x = 42 + 10
Combine like terms: 42 + 10 = 52
4x = 52
Divide each side by '4'.
x = 13
Simplifying
x = 13
