Hi! This should be the answer.
Slope-intercept form : y = mx + b
3) y + 4 = x
So, you need to move 4 to the other side, so that y is by itself.
Subtract 4 from both sides.
y = x - 4
~Hope I helped!~
Answer: So the answer wont be C or D because it doesn't get over 43.2 inches of water so if you do 43.2 -- 1.8 it will equal 41.4 inches
MARK ME BRAINLIEST!!!!!!!!!!!!!!!
Two lines that lie in the same plane and do not intersect are classified as parallel lines
Hence, -45 is the number which when added to the given fraction will give 2/3
Further explanation:
Given fraction is:
![\frac{23}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B23%7D%7B12%7D)
Let x be the number which has to be added to numerator and denominator
Then
![\frac{23+x}{12+x}=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B23%2Bx%7D%7B12%2Bx%7D%3D%5Cfrac%7B2%7D%7B3%7D)
Cross-multiplying
![\frac{23+x}{12+x}=\frac{2}{3} \\3(23+x)=2(12+x)\\69+3x=24+2x\\3x-2x=24-69\\x=-45](https://tex.z-dn.net/?f=%5Cfrac%7B23%2Bx%7D%7B12%2Bx%7D%3D%5Cfrac%7B2%7D%7B3%7D%20%5C%5C3%2823%2Bx%29%3D2%2812%2Bx%29%5C%5C69%2B3x%3D24%2B2x%5C%5C3x-2x%3D24-69%5C%5Cx%3D-45)
Hence, -45 is the number which when added to the given fraction will give 2/3
