PLEASE HURRY I WILL GIVE BRAINLEIST x + 3 = -x - 5

1 - 2x = -x - 3

x - 2 = -3x + 2

3y + 1 = 4y - 6

2 + 6x = 1 - x

5y + 4 = 4y + 5

Carter drank 15.75 gallons of water in 4 weeks. he drank the same amount of water each day.a. estimate how many gallons he drank in one day.b. estimate how many gallons he drank in one week.c. about how many days altogether will it take him to drink 20 gallons?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
