Explore the entire Algebra 2 curriculum: trigonometry, logarithms, polynomials, and more. Welcome to Mathematics 2. D. Use the rate formula, , to find the answer. What is the domain of the function f(x) = 2x – 4?1. To make the calculation easier, rewrite the formula as Next, if John and Julie work together, their total rate can be found by adding the individual rates together. You may solve a set of 10 questions with their detailed solutions and also a set of 50 questions, with their answers, in the applet to self test you background on how to Solve linear equations. Let t represent the number of hours the second car travels.The second car will catch the first car when both have traveled the same distance. A. How long after the second car leaves will it take for the second car to catch the first?9. Two cars are traveling north along a highway. In other words, their total rate working together is Therefore, it will take John and Julie hours, or 1 hour 12 minutes, to mow the lawn if they work together.3. Basic-mathematics.com. Click the button and find the first one on your computer. To find the value of y, substitute 2 for x in the first equation. How long will it take them to mow their lawn if they work together?6. Check this solution by substituting 3 into the original equation and making sure that the result is a true statement. So, set the two formulas equal to each other and solve for t.Therefore, the second car catches the first car six hours after it leaves.9. 7(x - 2) = 3(x + 4) Enter your answer in the space provided using mixed number format.

What are the two numbers? Therefore, the equation can be rewritten asThus, the solution is x = 3. © 2020 Study Guide Zone. Therefore, the function is defined for all real numbers.

Adding 36 to both sides of the original equation will complete the square: notice that x2 – 12x + 36 is indeed a perfect square trinomial because it can be factored as (x – 6)2.7. Consequently, the two possible solutions must be verified. Notice from the graph below that the function can go to the left and right without end.10.

Since we are giving information away, we cannot be held liable for incidental mistakes. 2. What should be added to both sides of the equation x2 – 12x = 5 in order to solve it by completing the square?8. D. The logarithm of a number is the exponent to which the base must be raised to in order to get that number. Just type!...Do you have some pictures or graphics to add? Intermediate Algebra Problems With Answers - sample 2:Find equation of line, domain and range from graph, midpoint and distance of line segments, slopes of perpendicular and parallel lines. Recall that a perfect square trinomial is a trinomial that can be factored as (ax + b)2or (ax – b)2. Then, simplify the result.The result is a quadratic equation. Select it and click on the button to choose it.Your email is safe with us. C. First, factor out any common factors from each of the three terms, 6×3, -4×2, and -16x. First, eliminate the denominators by multiplying both sides by x(x + 4). E. To solve an equation by completing the square, manipulate it algebraically so that one side (in this case, the left side) is a perfect square trinomial and the other side (the right side) is a constant. y = –3(2) + 4 = –6 + 4 = –2. C. To begin, rewrite the equation in the form ax2 + bx + c = 0 by subtracting 3 from both sides of the equation.6. For the given function, set up and solve an equation to determine when x2 – 8x + 15 is zero.Therefore, the vertical asymptotes are the lines x = 3 and x = 5.8. Set students up for success in Algebra 2 and beyond! And how do you go about learning it? Therefore, the solution of the system of equations will have values for each variable. B. The Language of Mathematics 4. Notice that the greatest common factor (GCF) of the coefficients is 2, and each term is divisible by x. It’s a fact of life: You need to be able to do algebra to handle physics problems. A. Solve it by factoring the left side and setting each factor equal to zero.Therefore, the possible solutions are x = –5 and x = 2. All information on this site is provided as is, without warranty.

Solution Let x be the first number. Simplify algebraic expressions. John can mow his lawn in 3 hours and his sister, Julie, can mow it in 2 hours. Great! To begin, substitute the left side of the first equation, –3x+4, for y into the second equation, and then solve for x.To find the value of y, substitute 2 for x in the first equation.Therefore, the solution of the given system of equations is x = 2,y = –2. Check this solution by substituting the values into the second equation and making sure the resulting equality is true. To do this, substitute them into the given equations and make sure that the result is a true statement.4. We will only use it to inform you about new math lessons.Everything you need to prepare for an important exam!If you can solve these problems with no help, you must be a genius!Learn about investing money, budgeting your money, paying taxes, mortgage loans, and even the math involved in playing baseball.Copyright © 2008-2019. 1. Since the first equation already has y isolated on the left side, it will be easier to use the substitution method than the elimination method to solve the system of equations.
