Answer:
-1, -12
Step-by-step explanation:
you take b which is 6 and make it negative, then you take a and multiply it by 2, which is 6. you then take the 2 numbers and put the -b over 2a in this formula -b/2a giving you -1 as your x value
after you do that, you input the -1 into the equation as x and the value you get out of that (-12) is the y value of the vertex

Answer:
1. 8.5 yards.
2. $42.5
Step-by-step explanation:
We have been given that Sue buys 5 pieces of fabric. Each piece is
yards long.
1. To find the total length of fabric bought by Sue we will multiply length of each fabric piece by 5.




Therefore, Sue bought 8.5 yards of fabric.
2. 1 yard of fabric costs $5.
So 8.5 yards of fabric will cost : 5*8.5


Therefore, the cost of total fabric bought by Sue is $42.5.
3(x^2 -x) -x
6x^2 -3x-x
6x^2 - 4x
we can simplify it more by take 2x as comman factor
so , 2x ( 3x -2 )
