Answer:
The number of children's tickets bought was 300 and the number of adult tickets bought was 700
Step-by-step explanation:
Let
x ----> the number of children's tickets bought
y ----> the number of adult tickets bought
we know that
-----> equation A
-----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for x
<em>Find the value of x</em>
therefore
The number of children's tickets bought was 300 and the number of adult tickets bought was 700
<span>So we wan't to know how much would 14 bags of seeds cost if three bags cost 14.16$. What we wan't first is the price of only one bag of bird seeds and lets call it x. To get that we need to divide the cost of three bags of seeds by 3 and we get that x=14.16$/3=4.72$. So now that we know how much one bag of seeds costs we can simply multiply it by 14 and get our answer: 14*4.72$=66.08$</span>
The correct answer is: [B]:
________________________________________________________
<span> f(x) = (x - 9)(x + 9)(x + 5); x= 9, -9, -5 .

-13>-5x+2>-28 subtract 2 from all expressions
-15>-5x>-30 divide each expression by -5
Be sure to reverse direction of signs when you divide/multiply by a negative value!
3<x<6
So the "graph" will be a infinitely high plane, or area, contained between the two vertical lines x=3 and x=6
