Answer:
We conclude that the slope between (s, t) and (u, v):
- slope = [v - t] / [u - s]
Step-by-step explanation:
We can find the slope between two points (x₁, y₁) and (x₂, y₂) using the formula
slope = [y₂ - y₁] / [x₂ - x₁]
In our case, the two points are
(x₁, y₁) = (s, t)
(x₂, y₂) = (u, v)
Thus, the slope between (s, t) and (u, v)
slope = [v - t] / [u - s]
Therefore, we conclude that the slope between (s, t) and (u, v):
- slope = [v - t] / [u - s]

Answer:
x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:
x = -8.20, 2.20.
Step-by-step explanation:
x^2 + 6x - 18 = 0
this will not factor so we use completing the square:
x^2 + 6x = (x + 3)^2 - 9 so:
(x + 3)^2 - 9 - 18 = 0
(x + 3)^2 = 27
x+ 3 = ±√27
x = - 3 ± √27
one inch---> 24.4 cm
inches in 24.4cm=> 24.4/2.5
=> 9.76cm (2 decimal places)
He got a discount of 32%, and saved 64$,
let the total amount without discount be x
according to the formula
32$=64×100/x
x=64×100/32
x=200$
