Question 1

This question is a part of the Weekly Math Review for Quarter 2. It assesses students’ understanding of concepts related to factorization and fractions. The key concepts covered in this question are factoring trinomials and simplifying fractions.

To solve this question, students need to factor the given trinomial and simplify the resulting fraction. The trinomial can be factored by finding two numbers that multiply to give the constant term and add up to give the coefficient of the middle term. After factoring the trinomial, students should simplify the fraction by canceling out common factors in the numerator and denominator.

To check their answer, students can multiply the factored trinomial by the simplified fraction and verify if it is equal to the original expression. A correct answer will satisfy this condition.

This question assesses students’ ability to apply factoring skills and simplification techniques to solve mathematical problems. It also tests their understanding of the relationship between factored expressions and fractions. By practicing such questions, students can improve their algebraic manipulation skills and develop a deeper understanding of factorization and fractions.

Question 2

In question 2, we are given a quadratic equation and asked to find the vertex of the corresponding parabola. The quadratic equation is expressed in the standard form: ax^2 + bx + c = 0. To find the vertex, we can use the formula x = -b/2a. Here, the coefficient of x^2 is a, the coefficient of x is b, and c represents the constant term. By substituting these values into the formula, we can calculate the x-coordinate of the vertex.

Let’s take a specific example to better understand the process. Suppose we have the equation 2x^2 + 4x + 1 = 0. Here, a = 2, b = 4, and c = 1. Plugging these values into the formula, we get x = -4/2(2) = -4/4 = -1. This gives us the x-coordinate of the vertex, but we still need to find the y-coordinate. To do this, we substitute the value of x back into the original equation.

Continuing with our example, we substitute x = -1 into the equation 2x^2 + 4x + 1 = 0. Simplifying, we get 2(-1)^2 + 4(-1) + 1 = 0, which becomes 2 + (-4) + 1 = 0. Simplifying further, we have -3 = 0. Since this equation is not true, we can conclude that there is no solution for y when x = -1.

Therefore, the vertex of the parabola represented by the equation 2x^2 + 4x + 1 = 0 does not exist. In general, the vertex of a quadratic equation can have various forms depending on the coefficients a, b, and c. It can be a minimum point (for a positive value of a) or a maximum point (for a negative value of a). The x-coordinate of the vertex can be found using the formula x = -b/2a, and the y-coordinate can be determined by plugging the value of x back into the equation.

Question 3

In this question, we are given a word problem that involves finding the area of a rectangle. The problem states that the length of the rectangle is three times the width. We are given the options for the width, which are 2, 4, 6, and 8.

To solve this problem, we need to use the formula for the area of a rectangle, which is length times width. Since we know that the length is three times the width, we can represent the length as 3x, where x is the width. Therefore, the equation for the area of the rectangle is 3x times x, or 3x^2.

To find the width that gives us the largest area, we need to evaluate the area for each option and compare the results. We can create a table to organize our findings:


From the table, we can see that the width of 8 gives us the largest area, which is 192. Therefore, the answer to this question is 8.

Question 4

Question 4 of the weekly math review focuses on solving a system of equations using the substitution method. The given system of equations is:

2x + y = 5

3x – 2y = -4

To solve this system using the substitution method, we start by solving one equation for one variable and then substituting it into the other equation.

In this case, we can solve the first equation for y:

y = 5 – 2x

Next, we substitute this expression for y into the second equation:

3x – 2(5 – 2x) = -4

Simplifying the equation, we get:

3x – 10 + 4x = -4

Combining like terms, we have:

7x – 10 = -4

Now, we can solve for x:

7x = 6

x = 6/7

Substituting this value of x back into the first equation, we can solve for y:

2(6/7) + y = 5

12/7 + y = 5

y = 5 – 12/7

y = 35/7 – 12/7

y = 23/7

Therefore, the solution to the system of equations is:

  • x = 6/7
  • y = 23/7

This means that the value of x is 6/7 and the value of y is 23/7.

Using the substitution method, we can solve for the unknown variables in a system of equations. It is important to simplify the equations, combine like terms, and solve step by step to find the solution.
