nikki makes $9.50 an hour working at current electronics. she plans to buy a dvd recorder that costs $269.60. write and solve an inequality describing how many hours h nikki will have to work to be able to buy the dvd recorder.
1. 9.50h ≥ 269.60; 29 hours
2. 269.60 + h ≥ 9.50; 31 hours
3. 269.60h ≥ 9.50; 30 hours
4. 269.60 – h ≥ 9.50; 28 hours

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4
