Answer:

Step-by-step explanation:
Given the expression:

First, we open the outer brackets

Therefore:

Answer:
C
Step-by-step explanation:
Observing that <em>f</em> has to be placed inside <em>g</em>, we can easily substitute x^2 - 3 in place of the x in x + 1, making it
(x^2 - 3) + 1 which equals
(x^2) - 2
Step-by-step explanation:
180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b)
we will proceed to verify each case to determine the solution of the problem
we know that
If the ordered pair is a solution of the inequality , then the ordered pair must be satisfied the inequality
we have

<u>case A</u> point 
Substitute the values of x and y in the inequality

-------> is true
therefore
the pair ordered
is a solution of the inequality
<u>case B</u> point 
Substitute the values of x and y in the inequality

-------> is false
therefore
the pair ordered
is not a solution of the inequality
<u>case C</u> point 
Substitute the values of x and y in the inequality

-------> is true
therefore
the pair ordered
is a solution of the inequality
<u>case D</u> point 
Substitute the values of x and y in the inequality

-------> is false
therefore
the pair ordered
is not a solution of the inequality
<u>case E</u> point 
Substitute the values of x and y in the inequality

-------> is false
therefore
the pair ordered
is not a solution of the inequality
therefore
<u>the answer is</u>


Adult ticket= $6.00 Child ticket= $3.00
Total=$168.00
$6 x 17 people=$102 $3.00 x 17 kids= $51 + 5 kids x$3=$168
Adult tickets sold= 17
Children's Tickets sold= 22
