The ordered pair (0,4) does not satisfy the inequality thus, it will be not the solution to the given inequality.
What is inequality?A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
As per the given inequality,
y ≤ x - 3
Put x = 0
y ≤ 0 - 3
y ≤ -3
Since 4 ≤ -3 is the wrong statement thus it will not satisfy the inequality.
Hence "The ordered pair (0,4) does not satisfy the inequality thus, it will be not the solution to the given inequality".

The given ordered pair is not the solution for y ≤ x − 3.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The inequality is given as y ≤ x - 3.
The x coordinate for the ordered pair (0,4) is 0.
And, the y coordinate is 4.
Substitute the value of x and y in the given inequality as follows,
y ≤ x - 3
=> 4 ≤ 0 - 3
=> 4 ≤ -3
Which is not true.
Hence, the ordered pair (0, 4) is not solution of the inequality y ≤x − 3.

In right triangle ABC, point D is on side BC, as shown. If BC= 5 x BD and the area of Triangle ABD is 8 in2, what is the area of Triangle ABC?
Answer: 40 in2
Step-by-step explanation:
Area of a triangle = 1/2 (base)(height)
Side AB is common to both triangles
BC = 5(BD)
Area ABD = 8, therefore Area ABC = 5(8) = 40
Which equation choice could represent the graph shown below?
The function representing the graph is f(x) = (x + 5)²(x - 3)². The correct option is (a).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given graph of the function cuts x axis at (-5,0) and (3,0) and y axis at (0,225) respectively.
Since the zeros of a function is the point at which it cuts the x-axis, the zeros at of the given functions are -5 and 3.
Which implies that the factors are (x + 5) and (x - 3) respectively.
The given factors are valid for options (a) and (d).
Now, at x = 0 f(x) should be 225.
It can be checked for both the options as follows,
(a) f(x) = (x + 5)²(x - 3)²
=> f(0) = (0 + 5)²(0 - 3)²
= 5² × -3²
= 225
Hence, the function that represents the given graph is f(x) = (x + 5)²(x - 3)².

Given that triangles ABC and DEF are similar triangles, we have the following:
Perimeter of triangle ABC = x
One side length of triangle ABC = 4 cm
Perimeter of triangle DEF = 12 + 6 + 9 = 27 cm
One side length of triangle DEF = 6 cm
Therefore:
x/27 = 4/6
Cross multiply
6x = (27)(4)
6x = 108
6x/6 = 108/6
x = 18
Thus, the perimeter of tr8angle DEF that is similar to triangle ABC is: 18 cm.

Last year at a certain high school, there were 60 boys on the honor roll and 100 girls on the honor roll. This year, the number of boys on the honor roll increased by 20% and the number of girls on the honor roll increased by 3%. By what percentage did the total number of students on the honor roll increase? round your answer to the nearest tenth (if necessary).
The percent increase in the total number of students on the honor roll is 9.4% .
In the question,
it is given that ,
last year , the number of boys in the honor roll is = 60 boys ,
the number of girls in the honor roll is = 100 girls ,
total number of students last year = 160
percent increase in the number of boys in the honor roll is = 20% ,
so , number of boys become = 60 + (0.20*60) = 72 boys ,
percent increase in the number of girls in the honor roll is = 3% ,
so , number of girls become = 100 + (0.03*100) = 103 girls ,
total number of students this year = 103 + 72 = 175 .
increase in number of students = 175 - 160 = 15
So , percent increase is = (15/160) × 100

Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building materials and how the strength relates to the length. The data are represented by the exponential function f(x) = 2x, where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals.
x = ㏑₂8 in the logarithmic function.
What is a logarithmic function?A logarithmic function is the inverse of an exponential function.
Given function if f(x) = [tex]2^{x}[/tex],
When strength is equal to 8 pascals, f(x) = 8
Therefore, 8 = [tex]2^{x}[/tex]
Taking log on both sides:
ln8 = ln[tex]2^{x}[/tex]
ln8 = xln2
or x = ln8/ln2
x = ㏑₂8

A publisher used 10 boxes to send 375 books to a local book retailer. The
small boxes hold 30 books and each large box holds 55 books. Determine
the number of small and the number of large boxes used.
Answer: Number of small boxes = 7, Number of large boxes =3
Step-by-step explanation:
Let x= Number of small boxes , y = Number of large boxes.
As per given , 30x+55y=375 (i)
x+y=10 (ii)
Multiply (ii) by 30, we get
30x+30y=300 (iii)
Eliminate (iii) from (i), we get
25y=75
⇒ y= 3 [Divide both sides by 25]
Put y=3 in (ii), we get
x+3=10 ⇒ x=7
Hence, Number of small boxes = 7, Number of large boxes =3

What is an equation ?According to algebra, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 4x + 5 = 15 consists of the two equations 4x + 5 and 15, which are separated by the 'equal' sign.
According to the given information
X + Y + Z = 2000000
0.07X + 0.085Y + 0.095Z = 157000
Y = 4Z
Y = 4Z is substituted into the first and second equations as follows:
X + 5Z = 2000000
0.07X + 0.085 (4Z) + 0.095Z = 157000
X = 2000000 - 5Z
0.07X + 0.435Z = 157000
0.07 (2000000 - 5Z) + 0.435Z = 157000
140000 - 0.35Z + 0.435Z = 157000
0.085Z + 140000 = 157000

-Wilson Middle School wants to rent tables for their weeklong art festival. One rental company charges a $20 setup
fee and $12 per table for the week. Another rental company charges a $30 setup fee and $10 per table for the week.
How many tables can the school rent for the charge to be the same for both companies?
Answer:
5 tables
Step-by-step explanation:
Let x be the number of tables the school needs to rent, and c be the total cost of renting the tables.
We can use the following equation to represent the cost of renting from the first company:
c = 20 + 12x
And we can use the following equation to represent the cost of renting from the second company:
c = 30 + 10x
As c is the same constant in both equations, we can say the following:
20 + 12x = 30 + 10x
Now we can solve this equation by simplifying:
20 + 12x = 30 + 10x
20 + 2x = 30
2x = 10
x = 5
Therefore, the school will need to rent 5 tables for the cost to be the same from both renting companies.
Answer: 5 tables
Step-by-step explanation:
The first rental company will charge $32 for one table.
The second rental company will charge $40 for one table.
So if we make a table, and keep adding $12 to the first company and $10 to the second it will look like this.
First company Second company Table
$32 $40 1
$44 $50 2
$56 $60 3
$68 $70 4
$80 $80 5
Therefore, the school can rent 5 tables for the same price in both companies.
