Answer:
y=1.4x+6.8
Step-by-step explanation:
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
y=1.4x+6.8
First, change 7 2/3 to an improper fraction
7 x 3 = 21 + 2 = 23
23/3 is the amount Maria made
Find a common denominator for all: 24
(23/3)(8/8) = 184/24
(5/6)(4/4) = 20/24
Subtract the amount she drank from the whole
184/24 - 20/24 = 164/24
Find 3/4 of the bottle
(164/24)(3/4) = 5.125
finally, divide the number gotten with 3
5.125/3 = 1.70
1.70 pints were in each bottle.
hope this helps
(2x + 7) + (2x) + (x + 18) = 180
5x + 25 = 180
5x = 155
x = 31 °
