Answer:
(x - 9)(x + 5)
Step-by-step explanation:
x² − 4x − 45 =
= x² + 5x - 9x - 45
= x(x + 5) - 9(x + 5)
= (x - 9)(x + 5)
Answer:
z=2
Step-by-step explanation:
60=-5(-6-3z)
60= 30+15z
60-30=15z
30/15=15z/15
2=z
33. "Of" in math problems means multiply therefore 55% or 0.55 multiplied by 60 is 33
Answer:
Undefined.
Step-by-step explanation:
We have been given coordinates of two points on a line. We are asked to find the slope of the line using given points.
We will use slope formula to solve our given problem.
, where,
m = Slope of line,
= Difference between two y-coordinates on the line.
= Difference between two x-coordinates of the same y-coordinates.
Let
and 
Substitute coordinates of the given points in slope formula:



Since the x-coordinates of both points are same which represents a vertical line, therefore, the slope of the line passing through given points is "undefined".
