Since the number ranges between 3 and 10, an equation can't be made because the number is always unknown or can be different every time
How to do the vertex is using the formula -b/2a
your a=-9 and b is -18 but it going to become +18 because you are multiplying the -(-18) which there a 1 in front the neg. you going to multiply the -9 by 2 and do 18/18 so your x= -1. You got your x, you going to put in the equation as y=-9(-1)^2-18(-1)-1 then you got your y... hope this is helpful :)
If you made $7 an hour and worked for 40 hours, every day for a year, you would make $14,560 a year and about $1,213.33 a month.
Because 7 x 40 = 280 (which is how much money you make a week.)
And 280 x 52 = 14,560 (because you would work for 52 weeks).
I hope this helped! Good luck and have a great night!
White sheep: 162 black sheep: 18
Numbers are a ratio of 9: 1, total 10 parts
180/10 =18
18 x 9 =162 18 x 1 =18
