Answer: See each part below.
1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.
3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D
4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.
True a sub graph is not part of a graph
For 13. the answer is w = -1.
Here are the steps
1. subtract 5 from both sides ( 3w = 2 - 5)
2. simplify 2 - 5 to -3 (3w = -3)
3. divide both sides by 3 ( finally the answer is w = -1.
)
Could be wrong but try 6/3 then 2
I would start by saying how much I enjoyed this lesson and how it has helped me in many ways I would also like to state how it was difficult at first but once I started to understand it, it became really easy and would like to thanks the teacher for teaching it.
