Step-by-step explanation:
Distrube out .5 first and the equation will be .5x+2
Then add 3 to both sides and you get y=.5x+5
18/20=27/x
18x=27*20
x=(27*20)/18=30
Answer: 30
This is a linear equation y = mx+b, where m is the slope and b, the y-intercept.
Since we know this graph passes through A(1,4) and B(5,6), we can find easily the equation:
1st- Calculate m = (y₂-y₁)/(x₂-x₁) → m = (6-4)/5-1) = 2/4 →m =1/2
Now y = (1/2) + b.
2nd. To calculate b, replace x and y by either the coordinate of A(1,4) or B(5,6)
Let's take A where x = 1 and y = 4 for instance:
y =(1/2)x + b
4=(1/2)(1) + b
4=1/2 + b
4-1/2 = b and b= 7/2
Finally te equation becomes: y = (1/2)x + 7/2
Answer:
(Hooke's law) is a fundamental relation that explains how a weight on a spring stretches that spring. There is a fundamental direct proportionality here, with a constant of proportionality called the ((spring constant)) .
