Li is making beaded necklaces. For each necklace, she uses 34 spacers, plus 2 beads per inch of necklace length. Write an equation to find how many beads Li needs for each necklace, where x is the length, in inches, of the necklace.

It’s going to be d. 4x^2-4x-19’

The slope of the function is 0.5.

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

Yo yo yup because it’s so cool and awesome dude
