Answer:
its the third one
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
x^3 + 2x^2 - 9x - 18 = x^2(x + 2) - 9(x + 2) = (x + 2)*(x^2 - 9)
(x + 2)/(x + 2)(x^2 - 9) = 1 / (x^2 - 9)
==============
1/(x^2 - 9) * (x^2 - 9)/(3x + 1) = 1/(3x + 1)
Yes B is correct.
Answer:
5 and 2/10
Step-by-step explanation:
You have to have a common denominator
Answer:
X = 1h15mins
Step-by-step explanation:
Rate Time Distance
Morgan 20 X 20X
Corona 25 X – ¼ 25(X – ¼)
If they meet each other, they need to travle the same distance, mean :
20X = 25(X – ¼)
X = 1.25
1 hour and 15 minutes
Answer:
Pat a) The graph in the attached figure
Part b) 
The slope is 
The y-coordinate of the y-intercept is 
Step-by-step explanation:
Part a) Which line represents the linear equation
?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0



The y-intercept is the point 
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0



The x-intercept is the point 
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
we have

convert to slope intercept form
isolate the variable y


The slope is 
The y-coordinate of the y-intercept is
