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
Answer:
The percent of change in 6 yards to 36 yards is 500% .
Step-by-step explanation:
Formula

Where
Change in value = Final value - initial value
As given
The percent of change in 6 yards to 36 yards.
Final value = 36 yards
initial value = 6 yards
Change in value = 36 - 6
= 30 yards
Put in the formula


Percentage = 500%
Therefore the percent of change in 6 yards to 36 yards is 500% .
y = 0x + 3
switch x and y and solve for y if possible
x = 0y +3
x = 3
Not a function because it doesn't pass the vertical line test .
