Answer:
Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so
An aircraft has a maximum of 220 economy seats
A flight will be cancelled if the money taken for the seats is less than $28,800.
so
therefore
Three inequalities that represent the situation are
For this case we have that by definition, the area of a triangle is given by:
Where:
h: It's the height of the triangle
b: It is the base of the triangle.
They tell us that the height of the triangle is 3 units more than the base. That means that if the base is "b" then the height is "b + 3". So, the area is:
ANswer:
Option C
A. 10p (10 dollars per photo)
b. 75-5
sorry but I can't remember how to do c.:(
(x² + 4x - 45)/(x² + 10x + 9)
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45
= (x² + 9x) - (5x + 45)
= x(x + 9) - 5(x + 9)
= (x + 9)(x - 5)
<span>
Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9
= (x² + x) + (9x + 9)
= x(x + 1) + 9(x + 1)
= (x + 1)(x + 9)
<span>
Hence, the given expr. = N/D </span>
= {(x + 9)(x - 5)}/{(x + 1)(x + 9)
= (x - 5)/(x + 1)
<span>
Restrictions : x ≠ - 1, x = 5 </span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
