Answer:
4x + 5y = - 23
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 )
rearrange 4y - 5x = 20 into this form
add 5x to both sides
4y = 5x + 20 ( divide all terms by 4 )
y = 
x + 5 ← in slope-intercept form
with slope m =
given a line with slope m then the slope of a line perpendicular to it is
= - 
, hence
= - 1 / = - 
y = - x + c ← is the partial equation
to find c substitute (- 2, - 3) into the partial equation
- 3 = 
+ c ⇒ c = - 
y = - x - ← in slope-intercept form
multiply all terms by 5
5y = - 4x - 23 ( add 4x to both sides )
4x + 5y = - 23 ← in standard form
The greatest common factor is 2x^2.
the largest number that divides evenly into <span>10x^5−16x^4+4x^2
is two.
the highest degree is x^2 so the answer would be 2x^2
