An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane. Which graph represents the solution to the inequality that finds the number of tickets the airline can still sell?
The inequality x ≤ 88 represents the situation, and the line graph first represents the solution to the inequality option first is correct.
What is inequality?
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The missing options are in the picture, please refer to the picture.
We have:
An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane.
Let's suppose the number of tickets is represented by x
Total number of passengers = 175
The inequality can be framed:
x + 87 ≤ 175
x ≤ 88
Thus, the inequality x ≤ 88 represents the situation, and the line graph first represents the solution to the inequality option first is correct.

Which rise and run would create a similar right triangle on the same line? a rise of 6 and a run of 8 a rise of 8 and a run of 6 a rise of 6 and a run of 5 a rise of 5 and a run of 6
A rise of 8 and a run of 6. Then the correct option is B.
What is a coordinate geometry?Coordinate geometry is the study of geometry using the points in space.
On a coordinate plane, a right triangle has points A (-5, -6), B (-5, -2), and C (-2, -2).
The distance between AB will be
AB² = (-5 + 5)² + (-2 + 4)²
AB² = 4²
AB = 4
The distance between BC will be
BC² = (-2 + 5)² + (-2 + 2)²
BC² = 3²
BC = 3
Then the rise and run will be
rise / run = 4 / 3
Then this can be written as
rise / run = 8 / 6
Then the correct option is B.

343x^3 + 216y^3
Each given factor written as a polynomial in descending order is; (7x + 6y)(49x² - 42xy + 36y²)
How to factorize Polynomials?We are given the polynomial;
343x³ + 216y³
343x³ + 216y³ is a sum of cubes and factors in general as;
a³ + b³ = (a + b)(a² - ab + b²)
Thus;
343x³ + 216y³ = (7x)³ + (6y)³
= (7x + 6y)((7x)² - 7x(6y) + (6y)² )

Box y, box y, and box z each contain a pencil and a highlighter. An item is drawn randomly from each box. A) Draw a tree diagram to represent the possible outcomes.
B) Determine the probability that the items drawn are two pencils and one highlighter.
The probability that the items drawn are two pencils and one highlighter is 0.25
How to draw the tree diagramTo do this, we make use of the following representations:
P represents PencilsT represents HighlightersSince there are three boxes, the number of possible outcomes is:
Outcomes = 2³
Outcomes = 8
See attachment for the tree diagram.
How to determine the probability?From the tree diagram, we have:
Outcomes = 8Two pencils and one highlighter (PPT) = 2So, the probability is:
P = 2/8
Evaluate
P = 0.25
Hence, the probability that the items drawn are two pencils and one highlighter is 0.25

Step-by-step explanation:
2x + 3y = 5
5x - 2y = -16
In order to find the value of a variable, we must eliminate the other variable by multiplying the equations to get the same coefficient.
We can multiply the first equation by 5 and the second one by 2 to get the same coefficient for x, the equations then become:
10x + 15y = 25
10x - 4y = -32
Now we can subtract:
19y = 57
y = 3
Since we know the value of y, we can substitute it into one of the original equations:
2x + 3(3) = 5
2x + 9 = 5
2x = -4
x = -2

Dixie lives in a $67,000 wood house in the country whose contents are valued at $12,000. She wants to know her monthly property insurance premium. Use the table above to calculate her monthly property insurance premium.
Without the table indicating the stated premium rates and applicable discounts, the monthly property insurance cannot be computed. Hence, on the assumption that the rate is 2.5% and the discount applicable is 7.5% the premium per month will come to $152.24
What is Property Insurance?
The simple definition of Property Insurance is, it is an insurance policy that covers a policyholder for the structure of a building and its contents against stated or agreed perils.
What is the calculation for the above?Given (based on assumption) that the applicable annual rate is 2.5%
and that:
Value of Wooden House = $67,000Value of the contents of the House = $12,000Applicable discount = 7.5% of premium/annumHence annual premium will be:
= (67,000 + 12000) * (2.5/100) * 0.925
Annual Premium Payable = $1,826.89.............A
Recall that we are asked to derive the monthly Insurance premium.
This is thus given as: Answer in A/12

A box in the shape of a rectangular prism has a width that is 5 inches greater than the height and a length that is 2 inches greater than the width. Write a polynomial expression in standard form for the volume of the box. Explain the meaning of any variables used.
The volume of the rectangular prism can be express in standard polynomial as follows:
x³ + 12x² + 35x
How to find the volume of a rectangular prism?volume of a rectangular prism = lwh
where
l = lengthw = widthh = heightTherefore,
let
height = x
width = x + 5
length = x + 5 + 2 = x + 7
Therefore,
volume = x(x + 5)(x + 7)
volume = x(x² + 7x + 5x + 35)
volume = x(x² + 12x + 35)

Answer: B and C
Step-by-step explanation:
Let's start off with some definitions.
Supplementary Angles: Two angles that add up to 180°.
Right Angle: One angle equal to 90°. Also identified with a square on the angle.
Complementary Angles: Two angles that add up to 90°.
Straight Angle: A straight line, which equals to 180°.
Right off the bad, we can knock off A and D because there is no proof of those being seen.
The angle <EFH is a right angle because it is equal to 90°. If you pay close attention, the angles <EFG and <GFH both add up to 90°, making them complementary angles.
Therefore, the correct answers are B and C.

The graph of a line goes up and to the right when:
When the coefficient of x is positive, the graph of a line rises and moves to the right. Option C is correct.
What is a graph?A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
The complete question is
"The graph of a line goes up and to the right when:
a) the coefficient of x is 0
b) the coefficient of x is negative
c) the coefficient of x is positive
d) there is no coefficient of x"
When the coefficient of x is positive, we know that the graph of a line will move upward and to the right.
Since we are aware that a line's upward and rightward movement indicates that the line is advancing, we will obtain a positive slope for the line, and we are also aware that the slope-intercept of a line is provided as:
y= mx+c
If m is a positive number, then positive is the coefficient of x.
The graph of a line goes up and to the right when the coefficient of x is positive.
Hence option C is correct.

Given Function of x : f(x)=6/-2+2[tex]e^{-0.3x}[/tex]
The given function showing the relationship between x and f(x) is f(x)=6/-2+2[tex]e^{-0.3x}[/tex] where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.
