3 quarters
Try this option:
common equation for line is y=kx+b, where k=tgα, b-number.
Rule: if y||y₁, then k=k₁.
It means that according to given conditions y₁=k₁x+b₁ ⇒ y₁=6x+b₁.
answer: y₁=6x+b₁
Both expressions are related because 12 divided by 4 equals to 3, and 1/4 of 12 equals to 3 too.
Answer:
x = 2.285 hours
y = 2.1425 feet
Step-by-step explanation:
Let us say that y represents the depth of the pool in feets and x represents the time in hours
The two set of equations are
y = 1/2x + 1
y= -1.25x + 5
Solving the above two equations we get
Subtracting eq (1) from eq (2), we get -
y-y = -1.25 x -0.5 x + 4
0 -1.75 x + 4
x = 4/1.75
x = 2.285 hours
y = 0.5 * 2.285 + 1
y = 2.1425 feet
