Answer:

g(x) = f(x) + 4 → Graph #5

h(x) = f(x + 4) → Graph #6

k(x) = f(x) - 4 → Graph #4

m(x) = f(x - 4) → Graph #3

Step-by-step explanation:

g(x) = f(x) + 4 → Graph #5

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) up by 4.

⭐ Graph #5 exhibits this transformation because I took the point (0,1) and shifted it up 4 units to get (0,5). Graph #5 is the only graph that showed point (0,5).

h(x) = f(x + 4) → Graph #6

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the x-values of f(x) by -4.

⭐ Graph #6 exhibits this transformation because I took point (0,1) and shifted it left 4 units to get (-4,1). Graph #6 is the only graph that showed point (-4,1).

k(x) = f(x) - 4 → Graph #4

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) down by 4.

⭐ Graph #4 exhibits this transformation because I took point (0,1) and shifted it down 4 units to get (0,-3). Graph #4 is the only graph that showed point (0,-3)

m(x) = f(x - 4) → Graph #3

⭐ This transformation of f(x) means that to get to g(x), you have to shift all of the x-values of f(x) right by +4.

⭐ Graph #3 exhibits this transformation because I took point (0,1) and shifted it right 4 units to get (4,1). Graph #3 is the only graph that showed point (4,1).

If a local park is open for biking every 12 day open for paddling every 8 day and if today the park is open for both options, then the next date when the park will be open will be on the 24th day. So Hana should pick 24th day from today next.

Every 12 day the local park is open its path for biking and every 8 day they open their lake or paddling. That is in every multiple of 12 days the biking option is available and every multiple of 8 days the paddling option is available.

If today both the biking and paddling option are open, then the next day where both options will be open can be determined by calculating the least common multiple of 12 and 8.

12 = 2×2×3

8 = 2×2×2

LCM (12, 8) = 2×2×2×3

LCM(12, 8) = 24

LCM of 12 and 8 is 24. So 24 days from today, the park will be open for both options.

Answer:

Binomial,Trinomial,Monomal,Linear equation

Step-by-step explanation:

In grade 11 math, the slope is a concept that is typically introduced in the study of linear equations and graphing.

The slope of a line serves as a gauge for its steepness. It is defined as the change in y (the vertical distance) divided by the change in x (the horizontal distance) between two points on the line.

A line's slope might be zero, positive, negative, or undefinable. A line with a positive slope rises as it goes from left to right, while a line with a negative slope falls as it goes from left to right. A line with a slope of zero is horizontal, while a line with an undefined slope is vertical.

The slope is often represented by the letter m in the equation of a line, which is written in the form y = mx + b. The slope of the line is the coefficient of the x term (the m in the equation).

For example, the slope of the line represented by the equation y = 3x + 4 is 3, while the slope of the line represented by the equation y = -2x + 1 is -2.

The  inequality in which involves one or more rational expressions is Rational inequality.

What is inequality?

Using the terms greater than, larger than or equal to, less than, or less than or equal to as a declaration of the order connection between two integers or algebraic expressions is known as inequality. Economic inequality comes in many forms, most notably wealth inequality measured by the distribution of wealth and income inequality measured by the distribution of income (the amount of money people are paid) (the amount of wealth people own). There are significant forms of economic inequality amongst various groups of people in addition to economic disparity between nations or states.

An inequality with a rational expression is said to be rational. Inequalities with rational expressions, such as 32x>1, 2xx34, 2x3x6x, and 142x23x, are referred to as rational inequalities.

The (a) Hole in the expression is x, (b) The vertical assumption is -10 and (c) the horizontal assumption is that the denominator is greater than the numerator.

You should know that a hole occurs if there is a common term between the the numeration and the denominator when factorized, For vertical assumption, the denominator must be equal to zero and horizontal assumption, numerator will be equal to denominator

The given expression is:

[tex]\frac{x^{2}-2x }{x^{3}-9x^{2} -10x }[/tex]

The Hole is

Factorize the numerator= x²-2x

x is common in the expression

x(x-2)

Factorize the denominator= x³-9x²-10x

x(x²-9x-10)

= [x²-10x+x-10]

x[(x²-10x)+(x-10)]

Simplify further to get

x[x(x-10)+1(x-10)]

=x[(x+1)(x-10)]

Combine numerator and denominator to see the hole

[tex]\frac{x(x-2)}{x(x+1)(x-10)}[/tex]

From the expression the hole is x

b. vertical assumption

The denominator =0

x³+9x²-10x=0

Differentiate to have

dy/dx= 3x²-18x-10

2nd order derivative is

d2y/d2x=6x-18

Applying limit as x approaches 0

6x-10

Therefore x=-10

c. horizontal assumption the numerator is less than the denominator

x²-2x<x³-9x²-10x

In conclusion, the Hole in the expression is x, The vertical assumption is -10 and the horizontal assumption is that the denominator is greater than the numerator.

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

There are two methods of finding factors: multiplication and division. In addition, rules of divisibility may also be used.

Let f (x) = x ³ - 3x²  + ax -10 be the given polynomial.

By factor theorem,  ( x - 5 ) is the factor of f (x) , if f ( 5 ) = 0

Therefore,

To compare two numbers, a, and b, we can write two inequalities:

a < b when a is less than b

a > b when a is greater than b.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We may write two inequalities to compare two numbers, a and b:

a < b

a > b

If a is less than b, then the first inequality is true and the second is false. If a is greater than b, then the first inequality is false and the second is true. Otherwise, if a and b are equal, then both inequalities are false.

We can determine which inequality is true by comparing the values of a and b and using the rules of inequality.

For example, if a=3 and b=5, then we can determine that a < b is true and a > b is false because 3 is less than 5.

On the other hand, if a=8 and b=2, then we can determine that a < b is false and a > b is true because 8 is greater than 2.
