Children should be able to recite the letters and alphabets typically by the age of three.

An alphabet is a standardized system of fundamental written graphemes that correspond to the phonemes of certain spoken languages. a group of letters or other symbols used to write one or more languages, especially if they are organized in a regular sequence. a set of symbols or signals used to represent letters.

Children should be able to recite the letters typically by the age of three. All kids, nevertheless, are unique. While some toddlers may learn when they are two, others might not begin until they are late in the third year. The majority of the time, repetition is how kids pick up the alphabet.

The system of inequalities is:

x + y ≤ 8      (1)

5x +8y ≥ 80    (2)

The graphical solution is attached and one possible solution is (-30,30).

What is inequality?

The relation between two unequal expressions is defined as inequality.

Given that, the person makes $15 per hour of lifeguarding and $8 per hour clearing tables.

It is also given that x represents the number of hours of lifeguarding and y represents the number of hours of clearing tables.

The person has at most 8 hours a week, therefore, it follows:

x + y ≤ 8      (1)

The earnings of the person in a week are:

15x + 8y

Since the earnings must be no less than $80, it follows:

15x +8y ≥ 80    (2)

Hence, the system of inequalities is:

x + y ≤ 8      (1)

5x +8y ≥ 80    (2)

The graphical solution is attached and one possible solution is (-30,30).

To easily recognize comparable triangles, you can apply three theorems that are peculiar to triangles.

Two triangles can be compared using one of three theorems: Angle-Angle (AA), Side-Angle-Side (SAS), and Angle-Angle-Side (SS-AS) (SSS).

The symbol representing two triangles with the same angles on all three sides is SSS, which stands for "side, side, side." If two triangles' third sides match those of another triangle, the two triangles are said to be congruent.

The SAS regulation states as much. If the two sides and included angle of one triangle match the two sides and included angle of another triangle, the triangles are congruent. Any angle formed by two specified sides is considered to be an included angle.

A triangle is comparable to another if its two matching angles are congruent, according to the AA postulate of Euclidean geometry. The AA postulate is derived from the observation that the total internal angle of a triangle is always equal to 180°.

The percent of the decrease in the average monthly revenue is 10%.

We can calculate the percent of the decrease by using the following formula:

The percent of the decrease = (previous revenue - current revenue) / previous revenue  × 100%

Last year, the average monthly revenue at the Cedarburg Times newspaper was $66,490.

This year, the average monthly revenue so far has been $59,841.

The percent of the decrease = (previous revenue - current revenue) / previous revenue  × 100%

previous revenue = $66,490.

current revenue = $59,841

The percent of the decrease = ($66,490 - $59,841) / $66,490 × 100%

The percent of the decrease = 6,649 / $66,490 × 100%

The percent of the decrease = 0.1 × 100%

Apply the multiplication operation, and we get

The percent of the decrease = 10%

(assuming a function from reals to reals)

So b:)

Step-by-step explanation:

The range is { -5, -3, 7 }

The range of values that can be plugged into a function is known as its domain. In a function like f, this set represents the x values (x). A function's range is the set of possible values that it can accept. The values that the function outputs when we enter an x value are in this set.

domain = x

range = y

when the domain is -1

y = 2(-1) - 3

y = -2 - 3

y = -5

range is -5

When the domain is 0

y = 2(0) - 3

y = 0 - 3

y = -3

range is -3

D = [tex]{b^{2} -4ac}[/tex] where the equation is of the form [tex]ax^{2} + bx + c = 0[/tex]

Therefore,

a = -3

b = 6

c = 2

Putting these values in formula of discriminant, we get

2. The limit still exists if there is a gap in the graph at the value that x is nearing and no other point for a different value of the function.

3. The limit does not exist if the graph exhibits a vertical asymptote, which is a pair of lines that approach the value of the limit and continue upward or downward without constraints.

The solution of the given system of equations 8x+3y=5 and 3x-2y=5 is x = 1 and y = -1

In this question we have been given a system of equations.

8x+3y=5                 ..........(1)

and 3x-2y=5           ..........(2)

We need to find the solution of the given system of equations.

As right hane side of both equations is equal, we equate LHS of both equations.

so, we get,

8x + 3y = 3x - 2y

⇒ 8x - 3x = - 2y - 3y

⇒ 5x = - 5y

⇒ x = - y                      .............(3)

By substituting x = - y in equation (1), we get,

8 ( - y ) + 3y = 5

⇒ - 8y + 3y = 5

⇒ - 5y = 5

⇒ y = - 1

Substitute above value of y in equation (3)

⇒ x = - (- 1)

Answer:

Step-by-step explanation:

To solve the equation 5(3+6a) = -15+6(5+5a), we need to use the rules of algebra to isolate the variable "a" on one side of the equation and simplify the other side.

First, we can distribute the 5 on the left side of the equation to obtain 53 + 56a = -15+6(5+5a). This gives us 15 + 30a = -15+6(5+5a).

Next, we can distribute the 6 on the right side of the equation to obtain 15 + 30a = -15+65 + 65a. This gives us 15 + 30a = -15+30 + 30a.

Now we can combine like terms on both sides of the equation to obtain 30a = -15 + 30, which simplifies to 30a = 15. Finally, we can divide both sides of the equation by 30 to obtain a = 0.5.

Therefore, the solution to the equation 5(3+6a) = -15+6(5+5a) is a = 0.5
