Answer:

Senior citizen tickets = $9

Student tickets = $11

Step-by-step explanation:

We begin by converting these into simultaneous linear equation;

Senior citizen tickets = a

Student tickets = b

5a + 9b = 144

14a + 6b = 192

5a = 144 - 9b

a = 144/5 - 9b/5

a = 28.8 - 1.8b

We now substitute this into the first equation

14(28.8 - 1.8b) + 6b = 192

403.2 - 25.2b +6b = 192

-19.2b = 192 - 403.2

b = -211.2/-19.2

b = 11

Put the value of b into either equation

5a + 9b = 144

5a + 9(11) = 144

5a +99 = 144

5a = 144-99

5a = 45

a = 9

Given the following absolute value function find the range f(x)= |x+5|-8
Flauer [41]
The minimum value for |x+5| is 0, so the minimum for f(x) is 0-8=-8.
There is no maximum for |x+5|, so neither does f(x).
Therefore the range of f(x)=|x+5|-8 is [-8,+inf) in interval notation, or
from -8 to infinity in words.

A jar contains $36.25 in quarters and nickels. How many quarters and dimes are in the jar? Please explain how u got the answer,
kumpel [21]
So, look:

36*4 = 144

There are 145 quarters in all.

And in nickels, there are:

144 * 5 = 720 + 5 = 725
There are 725 nickels in all.

Dimes: 144 * 10 = 1440 + 10 = 1450  (or you could do 145 * 10 and still get 1450. Like I did in the nickels and everything. :) )

= 1450 dimes 

I hope this helps!

The surface area of a sphere is S(x) = 4πx2, where x is the length of the radius of the sphere. Restrict the domain to create a
Orlov [11]
Given that the surface area of the sphere is S(x)=4πx², the inverse function will be obtain as follows: make x the subject of the function
S(x)/(4π)=x²
get the square root of both sides:
x=√[S(x)/(4π)]
replace x by S⁻¹(x) and S(x) by x
this will give us the inverse as :
S⁻¹(x)=√[x/(4π)]
The above implies that the inverse is the square root of the radius divided by 4π
