### Algebra

#### Expressions and equations

Expressions and equations are the ways of writing mathematical statements using symbols, such as variables, constants, operators, etc. Expressions are the combinations of symbols that represent a value, while equations are the statements that show the equality of two expressions. Here are some examples of expressions and equations questions and answers from Mr Collins Maths Homework Answers:

Question

Answer

What is the value of x in the equation 2x + 5 = 13?

To find the value of x, we need to isolate x on one side of the equation by using inverse operations. 2x + 5 = 13 Subtract 5 from both sides: 2x = 8 Divide both sides by 2: x = 4 Therefore, the value of x is 4.

What is the value of y in the expression 3y - 7 when y = 2?

To find the value of the expression, we need to substitute y with 2 and simplify. 3y - 7 = 3(2) - 7 = 6 - 7 = -1 Therefore, the value of the expression is -1.

What is the simplified form of the expression 2(x + 3) - (x - 5)?

To simplify the expression, we need to apply the distributive property and combine like terms. 2(x + 3) - (x - 5) = 2x + 6 - x + 5 = (2x - x) + (6 + 5) = x + 11 Therefore, the simplified form of the expression is x + 11.

What is the expanded form of the expression (x + 2)(x - 3)?

To expand the expression, we need to multiply each term in the first bracket by each term in the second bracket and simplify. (x + 2)(x - 3) = x(x - 3) + 2(x - 3) = x - 3x + 2x - 6 = x - x - 6 Therefore, the expanded form of the expression is x - x - 6.

What is the factorised form of the expression x + x - 12?

To factorise the expression, we need to find two numbers that multiply to give -12 and add to give +1. The two numbers are +4 and -3. x + x - 12 = (x + 4)(x - 3) Therefore, the factorised form of the expression is (x + 4)(x - 3).

#### Functions and graphs

Functions and graphs are the ways of representing relationships between two sets of values, such as input and output, independent and dependent variables, etc. Functions are the rules that assign each input to exactly one output, while graphs are the visual representations of functions using points, lines, curves, etc. Here are some examples of functions and graphs questions and answers from Mr Collins Maths Homework Answers:

Question

Answer

What is a function?

A function is a rule that assigns each input to exactly one output. For example, f(x) = x + 1 is a function that takes any number x as an input and returns its square plus one as an output.

How do you write a function in function notation?

To write a function in function notation, we use a letter (usually f) followed by parentheses containing a variable (usually x) to represent the input. Then we write an equal sign and an expression involving the variable to represent the output. For example, f(x) = 2x - 5 is a function that takes any number x as an input and returns twice that number minus five as an output.

How do you evaluate a function for a given value of the input?

To evaluate a function for a given value of the input, we substitute the input value into the expression that defines the function and simplify. For example, to evaluate f(x) = 2x - 5 for x = 3, we write f(3) = 2(3) - 5 = 6 - 5 = 1. Therefore, f(3) = 1.

How do you graph a function using a table of values?

To graph a function using a table of values, we choose some values for the input variable and calculate the corresponding values for the output variable using the function rule. Then we plot the ordered pairs (input, output) on a coordinate plane and join them with a smooth curve or line. For example, to graph f(x) = x + 1, we can use the following table of values:

x

-2

-1

0

1

2

f(x)

5

2

1

2

5

Then we plot the points (-2, 5), (-1, 2), (0, 1), (1, 2), and (2, 5) on a coordinate plane and join them with a smooth curve. The graph looks like this:

How do you find the domain and range of a function?

The domain of a function is the set of all possible input values, while the range of a function is the set of all possible output values. To find the domain and range of a function, we can use different methods depending on the type of function. For example, to find the domain and range of f(x) = x + 1, we can use the following method:

To find the domain of a function, we look for the possible values of the input variable that make the function defined. To find the range of a function, we look for the possible values of the output variable that result from the function rule. For f(x) = x + 1, we can use the following method:

Domain: The input variable x can take any real number as its value, since there is no restriction on squaring or adding 1 to any number. Therefore, the domain of f(x) = x + 1 is all real numbers, or (-, ).

Range: The output variable f(x) can take any real number that is greater than or equal to 1, since squaring any number always gives a non-negative result and adding 1 to it always gives a positive result. Therefore, the range of f(x) = x + 1 is all real numbers that are greater than or equal to 1, or [1, ).

### Geometry

#### Shapes and angles

Shapes and angles are the ways of describing the forms and sizes of different objects in space. Shapes are the figures that have boundaries and dimensions, such as circles, triangles, squares, rectangles, etc. Angles are the measures of the rotations between two rays that share a common endpoint, such as acute, right, obtuse, etc. Here are some examples of shapes and angles questions and answers from Mr Collins Maths Homework Answers:

Question

Answer

What is a circle?

A circle is a shape that consists of all the points that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius. The length of the boundary of the circle is called the circumference.

What is a triangle?

A triangle is a shape that has three sides and three angles. The sum of the angles in a triangle is always 180 degrees. Triangles can be classified based on their sides (equilateral, isosceles, scalene) or their angles (acute, right, obtuse).

What is a square?

A square is a shape that has four equal sides and four right angles. A square is also a type of rectangle and a type of parallelogram.
