If the two linear equations have the same slope (and different y-intercepts), the lines will be parallel. Since parallel lines never intersect, a system composed of two parallel lines will have NO solution (no intersection of the lines.
Answer and Step-by-step explanation:
The given function is:
F(y) =1 – 1/y2 , 1 ≤ y < ∞
Verify function is valid
Limy->-∞f(y) = Limy->-∞ 0 = 0
Limy->∞f(y) = Limy->∞ 1 – 1/y2
= 1, for y ≤ 1
F(y) = 0 is constant. For y > 1, f”(y) = 2 / y3 > 0
So, function is increasing. Therefore f(y) is cdf.
Probability density function
The probability density function is
F(y) = d/dy f(y) = {(2/y2 if y>1o if y≤1 )}
z = 5(y+1)
F (z) = p (z ≤z) = p (5(y+1) ≤z)
= p(y ≤ (z/5) – 1)
F (z) ={(0 if z≤0 and 1-1/(z/5-1)2 if z>0 )
4 + 5(x - 7)²
4 + 5(8 - 7)²
4 + 5(1)²
4 + 5(1)
4 + 5

Answer:
y=20x+150
Step-by-step explanation:
Sandy has 150 dollars ALREADY in her account, so each time she earns the money it is building upon. 20x (x because we don't know for how many months.)
Hope this helps ;)
