The graph for the inequality is attached below.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Each student ticket sells for $6.50 and each adult ticket sells for $11.

let the number of student ticket sold be x and number of adult ticket sold be y.

so, the inequality is

x + y < 130

and, 6.5x + 11y >1100.

Solving the inequality we get

x= 73.33 and y = 56.667

Now, if they sell at least 90 adult tickets then they sell at most 40 children ticket.

Hence, the solution is (73.33, 56.667).

Answer:  x = 1,  y = -1

Step-by-step explanation:

The elimination method is a technique for solving systems of linear equations.

1) 4x-6y=10

2) 9x+2y=7

in the second equation

it multiply with 3

then

3×(9x+2y=7)

= 27+6y= 21

We notice that the first equation has a 6y term and the second equation has a -6y term. These terms will cancel if we add the equations together—that is, we'll eliminate the x terms:

then add 1 + 2 equations

    4x-6y =  10 _____1)

   27+6y= 21   _____2)

then we will get

    31x+0  =  31

     31x= 31

     where x = 31/31= 1

          then x = 1

      if value of  x substitute in the equation ____1)

                           4x+6y =  10

                           4×1+6y =  10

                            6y = -6

The 3 main exponent properties are:

The product of powers property states that when you multiply two numbers with the same base, you can add the exponents to find the result. For example, (2^3) * (2^4) = 2^(3+4) = 2^7

The quotient of powers property states that when you divide two numbers with the same base, you can subtract the exponents to find the result. For example, (2^5) / (2^3) = 2^(5-3) = 2^2

The power of a power property states that when you raise a power to another power, you can multiply the exponents to find the result. For example, (2^3)^2 = 2^(3*2) = 2^6

These three properties help simplify algebraic expressions that include exponents and make it easier to solve equations and perform other mathematical operations.

Using simple mathematical operations, we know that we will get a change of $0.5.

An operation is a function in math that transforms zero or more input values into a strictly delineated output value.

The operation's arity is influenced by the number of operands.

For all real numbers, the four fundamental arithmetic operations in mathematics are: Finding the sum in addition ('+') Subtraction (Difference-finding; "-" Multiplication (Identifying the result; "×" Finding the quotient in division ("÷)

So, we know that:

Grapes cost $1.99.

We purchased 2.25 pounds of grapes.

The change we will receive if we gave a $5 bill will be:

5 - (1.99*2.25)

5 - 4.4775

0.5225

Rounding off: $0.5

Therefore, using simple mathematical operations, we know that we will get a change of $0.5.

The unit for area of a triangle is square units.

The area of a triangle is the amount of two-dimensional space that it occupies.The law of cosines to calculate the length of the third side, and then use the formula to calculate the area.

The formula for calculating the area of a triangle is A = ½ × base × height. The unit for the area of a triangle is typically square units such as square meters (m2), square kilometers (km2), square feet (ft2), and square inches (in2).To calculate the area, you need to measure the base and height of the triangle and multiply them together. Then, you need to divide the product by two. For example, if the base of the triangle is 4 cm and the height is 6 cm, then the area A = ½ × 4 cm × 6 cm = 12 cm².

The solution to the system of equations y = -3x - 2 and 5x + 2y = 15 is (-19, 55).

A system of linear equations is a set of two or more equations which includes common variables. The solution to a system of equations, is the value of the unknown variables used in the equations that satisfies both equations.

Given two linear equations in x and y,

y = -3x - 2     (equation 1)

5x + 2y = 15     (equation 2)

Use substitution method to find its solution. Since the first equation is already expressed as y in terms of x, substitute the first equation to the second equation.

5x + 2y = 15     (equation 2)

5x + 2(-3x - 2) = 15

5x - 6x - 4 = 15

Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solve for x.

5x - 6x - 4 = 15

-x = 15 + 4

x = -19

Substitute the value of x in the first equation and solve for y.

y = -3x - 2     (equation 1)

y = -3(-19) - 2

y = 55

Hence, the solution of the given system of equations is (-19, 55).

The sum of the infinite geometric series is 10

From the values that we have, the first term a1 = - 20, the common ratio r = 3

From the above we can get the first 5 terms of the geometric series. We do this by multiplying each number derived by 3

this would be :

-20, -60, -180, -540 , -1650 ...

The formula for the sum of the infinite geometric series is given as

S = a1 / 1 - r

from the question we have

a1 = -20

r = 3

we would put the values into the formula

S = -20 / 1 - 3

S = -20 / -2

s = 10

Hence the sum is given as 10

Exponents are a way to represent the repeated multiplication of a number by itself. The exponent is written as a small number raised to the right of the base number.

For example, in the expression 2^3, 2 is the base and 3 is the exponent. This means 2 multiplied by itself 3 times, equal to 2 x 2 x 2 = 8. The exponent tells how many times the base is multiplied by itself.

In grade 7, students typically learn the basic rules of exponents such as how to multiply and divide numbers with the same base, and how to raise a power to a power. They also learn about scientific notation, which is a way of writing very large or tiny numbers using exponents.
