x>-4 is the solution of the inequality -8x < 32

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is -8x < 32

Minus eight times of x less than thirty two.

We need to solve for x which is a variable.

Divide both sides by 8

-x<4

x>-4

Hence, x>-4 is the solution of the inequality -8x < 32

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

Step 1: Form an equation for the amount of money Troy has received after m months.

If the total months that Troy's grandfather has given him money is m, then the number of months that Troy's mother has given him money is m - 3.

⇒ Total amount in account = 300 + 75m + 40(m - 3)

                                             = 300 + 75m + 40m-120

                                             =180 + 115m

                                            =5(36+23m)

The line representing the equation part of the constraint 7x1 + 4x2 28 goes through the following two points e. none of the above.

The equation of a line can be represented as y = mx + b, where m is the slope of the line and b is the y-intercept. The line representing the equation of a constraint, such as 7x1 + 4x2 = 28, would be a straight line in a two-dimensional graph.

The points given in the options a, b, c, and d are pairs of x and y coordinates. To determine if any of these points lie on the line representing the constraint equation, we would need to substitute the x and y values into the equation and see if the equality holds.

For example, for option a, if we substitute x = 4 and y = 0 into the equation, we get 7 * 4 + 4 * 0 = 28, which is not true. Hence, none of the given points in the options lie on the line representing the constraint equation.

The solution of the system of equation is , x= -4 & y= -8.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

from the given graph we get,

one line is passing through the points (0,10) , ( 4,28)

so, the equation of the line can be,

4y= 18x + 40

and, second line is passing through the points (0,8) , (1,12)

so, the equation of the line can be,

y= 4x+8

solving the equations we get,

x= -4

y= -8

Hence, The solution of the system of equation is , x= -4 & y= -8.

We have that the polygon is one with eight sides, that is, it is a regular octagon.

To determine the interior angle, we have

(n - 2) 180

n is the number of sides

(8-2)180

1080 degrees

Now, divide it by the number of sides

1080/8 = 135 degrees

Note that angles on a straight line is equal to 180

Then,

x + 135 = 180

Collect like terms

x = 180 -135

The probability that the car selected was a domestic car and older than 2 years is 0.63 or 63%.

Probability is a mathematical concept that quantifies the likelihood or chance of an event occurring. It is a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. In between, probabilities reflect the degree of certainty that an event will occur, with values closer to 1 indicating a higher likelihood of occurrence and values closer to 0 indicating a lower likelihood.

The probability of an event is calculated by taking the ratio of the number of favorable outcomes to the total number of possible outcomes.

domestic car older than 2 years/total domestic cars = (28 + 12 + 23)/100 = 63/100 = 0.63 = 63%

Therefore, the probability of selecting a car that is less than 2 year given that it is a domestic car is 0.63 or 63%.

The area of the figure made up of a semicircle and a triangle is 63.25 ft²

An equation is a mathematical expression that contains two or more numbers and variables linked together by mathematical operations such as exponents, multiplication, division, addition, subtraction and so on.

The figure is made up of a semicircle and a triangle.

The semicircle has a diameter of 10 feet. Hence:

Area of semicircle = (1/2) * π * diameter²/4

Substituting:

Area of semicircle = (1/2) * π * 10²/4 = 39.25 ft²

The triangle has a base of 8 ft and height of 6 ft. hence:

Area of triangle = (1/2) * base * height

Substituting:

Area of triangle = (1/2) * 8 ft * 6 ft = 24 ft²

The area of the figure = Area of triangle + Area of semicircle

Area of figure = 24 ft² + 39.25 ft² = 63.25 ft²

The area of the figure is 63.25 ft²

The distance between the third base and the player is 150 feet.

Pythagoras' theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base, and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle of 90°. The sides of a right triangle (say a, b, and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.
