Answer:
The solution to the equation are x = 5.089 and x = -0.589
Step-by-step explanation:
Given:
x(at the power of 2) = 6 + 9x
To Find:
The solution of the equation = ?
Solution:
The given equation can be written as
=>
=>
=>
Using the quadratic formula,
where
a= 2
b = -9
c = -6
Substituting these values,
x =5.089 x = -0.589
Answer:
y = - x -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 5, - 4) and (x₂, y₂ ) = (- 1, - 6)
m = =
= -
, thus
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, - 6), then
- 6 = + c ⇒ c = - 6 -
= -
y = - x -
← equation of line
