Answer:
a
Step-by-step explanation:
if x is equal to -1, if you add 1 you get 0 so the answer is greater than or equal to 0
Answer:
Step-by-step explanation:
step 1
Find the slope of the line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the given line is 
therefore
The slope of the line parallel to the given line is
step 2
Find the equation of the line in point slope form
we have
substitute
Answer:y=200 students
Step-by-step explanation:Let x = the number of adult tickets sold
Let y = the number of student tickets sold
x + y = 375 x = 375 - y
7.50x + 4.50y = 2212.50 Multiply both sides of this equation by 10 to remove the decimal points.
75x + 45y = 22,125
75(375-y) + 45y = 22,125
28,125 - 75y + 45y = 22,125
-30y = -6000
y = 200 student tickets
Radical 27 is an irrational number and here's why.
Radical 27 can be simplified to 3 radical 3, or 3 times radical 3.
Since radical 3 is an irrational number, as you can see by typing it into a calculator, multiplying it by 3 would still result in a irrational number.
Hope this helps!
