SAT Prep: Test 1 Section 6 Part 3

Practice solving two equations with two unknowns. Here are five problems for using the substitution method. Included are clear, concise step-by-step instructions for the learner to follow. Problems start out easy and gradually get...

An equation is an equation is an equation. Scholars see there are many ways to solve them when they first sort a set of linear equations as written in standard form, point-slope form, or slope-intercept. They then write equations in all...

Ninth graders identify and describe the x-intercept as the place where the line crosses the x-axis as it applies to football. They create their own differentiations to reinforce the distinction between the x-intercept and the...

Finishing up this practice test, Sal shows how to complete the graphing and linear equations in problems 13-14. Students will rest assured after seeing him deftly navigate the ins and outs of these diagrams, making the SAT seem less...

If it takes a long time to complete the problems on the math SAT, it doesn't matter if they are correct - the problems that are left over will count against the student's score. Sal takes care to show quicker ways to complete problems...

Helping students realize the common missteps in solving the average SAT problem, Sal creates a lens through which students can clearly see the correct and incorrect approach to each type of problem. He points out what a student might...

Clarifying that speed matters more than rigor on the SAT, Sal takes care to show students the most efficient and easiest ways to solve various math problems. Those who get stuck on certain types of problems would benefit from his...

Root for those learning about roots. An installment of an extensive playlist covering derivatives focuses on using linear approximations to estimate roots. The example problem shows how to find the fourth root of 15 without a calculator.

In this online, interactive worksheet (7), students complete ten problems in 12 minutes to help prepare then to take the SATs. The problems vary in difficulty and content.

Pupils practice examining the tangent to a function to estimate the value of the function near the point of tangency. They view errors associated with those approximations, determine overestimates and find intervals that guarantee a...
