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.
