Hi Mike, can you explain how to solve SAT 8, Section 3, #6 as a “system of equations?” Thanks.
Hi Mike, I’m asking about SAT 8, Section 3, Number 7. Is it always best to immediately plug in answer choices on questions like this? For the algebraic practice, I rewrote the equation as a quadratic and solved for (x=5) and (x= -1). Then sub’d each value back into the given equation to find that only (x=5) worked. OK…but what a time-killer at #7 out of 20. Any other solution path to consider? Thanks!

Hi Mike. How would you do practise test 8, section 3 question 11? Can you explain the whole polynomials to an odd/even degree etc. The collegeboard answer was a little confusing
