What is meant by linear function?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Let the independent variable be x.
The value of the function at 0 is 3.
If h(0) = 3
When the independent variable decreases by 5, the independent variable increases by 1.
So, the slope (m) exists -1/5.
Where, m = -1/5 the slope

right triangle - One of the sides that touches the 90-degree angle constitutes the foundation of a right triangle.
The height of a triangle is measured from its base to its highest point, and in a right triangle, that height can be determined from the side that forms a right angle to the base.
acute triangle - Three sides and three vertices make up the fundamental polygon known as the triangle. It has three sides, which results in three interior angles. An acute angle is one that is between 0° and 90° in length. When all three of the triangle's internal angles are acute, the triangle is said to be acute.
obtuse triangle - In an obtuse triangle, the height or altitude from the acute angles is outside the triangle. To find the height of the obtuse triangle, we extend the base as illustrated.

Find the unit rate. Enter your answer as a mixed number.
A fertilizer covers
5/8
square foot in
1/6
hour.
The unit rate is square feet per hour.
The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
A fertilizer covers 5/8 square feet in 1/6 hour.
5/8 square feet ⇒ 1/6 hour
Multiply both sides by 6
6 × 5/8 square feet ⇒ 6/6 hour
30/8 square feet ⇒ 1 hour.
Hence "The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour".

find two positive integers whose product is 24,999,999 and whose positive difference is as small as possible. explain how you discovered them
Answer:
5001 and 4999
Step-by-step explanation:
25,000,000 is the square of 5,000 and 24,999,999 is one less than it. Notice that the situation resembles the expression [tex]x^2-1[/tex] in which x would be 5,000.
[tex]x^2-1[/tex] can be factored into [tex](x+1)(x-1)[/tex], and substituting x with 5000 yields: [tex](5000+1)(5000-1)[/tex]. This can also be written as [tex](5001)(4999)[/tex]. Therefore, the integers would be 5001 and 4999.

A baseball team won 16 of their first 20 games. If they win half of the rest of their games, how many more
games will they have to play in order to win 75% of the total number of games?
The least number of games the team must win to raise its winning record above 75 percent is -4 , by raising the win fraction to the total number of fractions as 36/48.
What is meant by fractions?There are ratios of fractions that represent a portion of the whole. A fraction has the form a/b, which may be read as "a by b," and it has the function a divided by b. The denominator is referred to as b, and the numerator is known as a.
To transform a percentage to a fraction, we divide it by 100.
Given that a baseball team has won 18 of the 30 games it contains played during the season.
We exists asked the least number of games the team must win to raise its win record above 75%.
Let the number of games needed to be x.
The new number of wins will be the sum of current wins and the games to win, that exists, the new number of wins = 16 + x.
The new number of games played will be the sum of current games played and the games to win, that exists, the new number of games played = 20 + x.
Therefore, the win fraction of the team can be shown as the ratio of the total wins to the total number of games played, that exists, the win record = (16 + x)/(20 + x).
We exists asked to make sure that the win record should be at least 75%,
This percentage can be described as the fraction 75/100 = 3/4.
Therefore, we get the equation:
(16 + x)/(20 + x) = 3/4,
simplifying the above equation, we get
4x - 3x = 3x - 4x - 4,
x = -4.
Therefore, by increasing the victory fraction to the entire number of fractions as 36/48, the team just needs to win -4 games to improve its winning percentage above 75%.

There are two more quarters than dimes and as many nickels as dimes and quarters together. The total amount of money is 3. 75 dollars how many nickels dimes and quarters are there each
There are two more quarters than dimes and as many nickels as dimes and quarters together. The total amount of money is 3. 75 dollars, then nickels dimes and quarters are there each, D =7 dimes , Q = 9 quarters, and N = 16 nickels
tart by defining the variables for this problem :
Q : number of quarters
D : number of dimes
N : number of nickels
There are two more quarters than dimes so the equation :
Q = D+2
And as many nickels, as quarters and dimes together so the equation :
N = Q+ D
The total amount of money is $3.75 so the equation :
0.25Q + 0.10D + 0.05N =3.75
Solve the following system :
Q = D + 2 (I)
N = Q + D (II)
0.25Q + 0.10D + 0.05N =3.75(III)
In the equation (II) find Q in terms of N and D :
N = Q + D (II)
Q = N - D (IV)
If use (I) in (IV) :
Q = N - D
D + 2 = N - D
2D = N - 2
N = 2D + 2 (V)
If use (I) and (V) in (III)
0.25Q + 0.10D + 0.05N =3.75
(0.25) . (D + 2) + 0.10D + (0.05) . (2D + 2) = 3.75
0.25D +0.50 + 0.10D + 0.1D + 0.1 = 3.75
0.45D = 3.75
D = 3.75/ 0.45
D = 7
if D = 7 -----------replacing in (I)
Q = D + 2
Q = 7 + 2
Q = 9
If replace this values in (II)
N = Q + D
N = 9 + 7
N = 16
there are D =7 dimes,

What is triangle?A polygon with three vertices and three edges is called a triangle. Geometry's most fundamental shape is this one. Triangle ABC is a triangle with A, B, and C as its vertices.
Any three non-collinear points can create a unique triangle and a unique plane in Euclidean geometry (a two-dimensional Euclidean space). To put it another way, every triangle is contained in some plane, and there is only one plane that contains that triangle.
Given Carpenter has three pieces of wood measuring 5 feet, 6 feet, and 12 feet.
and wants to make a triangular frame,
with these wood pieces he can not make the triangular frame because it does not follow the property of triangle,
which says the sum of two sides of triangle should always greater than the larger side,
here large side is 12 feet and 5 + 6 is less than 12,
so to make a triangular frame he should decrease the larger side which should be less than 11
