Answer

A rectangle with dimensions labeled as 8 and 3, and an area labeled as 5 square units.

Question 3

Explain why the equation $$2x + 3 = 11$$ has a unique solution.

Accepted Answer

Because it is a linear equation with one variable.

Answer

Because it is a quadratic equation with two variables.

Answer

Because it is a cubic equation with three variables.

Answer

Because it is a polynomial equation with no variables.

Question 4

Evaluate the implications of the solution $$x = 5$$ for the inequality $$x + 2 > 6$$ .

Accepted Answer

The solution implies that $$x$$ must be greater than 4.

Answer

The solution implies that $$x$$ must be less than 4.

Answer

The solution implies that $$x$$ must be equal to 4.

Answer

The solution implies that $$x$$ must be less than 6.

Question 5

Which graph correctly represents the function $$y = 2x + 1$$ ?

Accepted Answer

A line passing through the points (0, 1) and (1, 3).

Answer

A line passing through the points (0, 0) and (1, 2).

Answer

A line passing through the points (0, 2) and (1, 4).

Accepted Answer

4

Answer

2

Answer

8

Answer

16

Question 7

Use a diagram to solve the problem: A triangle has sides of lengths 3, 4, and 5. What type of triangle is it?

Accepted Answer

Right-angled

Answer

Equilateral

Answer

Isosceles

Answer

Scalene

Question 8

Explain the reasoning behind the solution to the equation $$x^2 = 9$$ .

Accepted Answer

The solutions are $$x = 3$$ and $$x = -3$$ because squaring either value results in 9.

Answer

The solution is $$x = 3$$ because only positive numbers can be squared.

Answer

The solution is $$x = -3$$ because only negative numbers can be squared.

Answer

There is no solution because $$x^2$$ cannot equal 9.
