Hello :
6x² + 480 = 0
x² = -480/6
x² = - 80
in : R ... no roots
in : C
x² = 80i² ..... ( i² = -1)
the roots are : √80 i , - √80 i
Answer:
7>x
Step-by-step explanation:
First you expand the brackets/parenthesis
9(2x-3) = 18x - 27
12x>18x-27 -15
Collect like terms, so take 15 from -27
-27 -15 = -42
12x>18x - 42
Take the -42 to the other side by adding 42 to both sides
12x + 42>18x
Take 12x from both sides
42>6x
Divide both sides by 6 and you have your answer
7>x

Answer:
Step-by-step explanation:
We can start with the point-slope form of the equation for a line. To meet the given requirements, we can use a point of (5, 0) and a slope of -1. Then the equation in that form is ...
y -0 = -1(x -5)
Simplifying gives the slope-intercept form:
y = -x +5 . . . . . . . use the distributive property to eliminate parentheses
Adding x to both sides gives the standard form:
x + y = 5

<em>Explanation</em>
We know the line has the required intercept and slope because we chose those values to put into the point-slope form. Conversion from one form to another made use of the rules of equality, the additive identity element (y-0=y), and the distributive property.
