Answer:
f(x)= 20 h(x)= -4
Step-by-step explanation:
ive learnd this already :)
Let's first start off with an equation to represent Celeste's budget:

Where:
'h' is the money in dollars that she needs to get her hair cut
'p' is the money in dollars that she needs to get her hair permed
'l' is the money in dollars that she needs for lunch
Now let's simplify this equation using the information that was given:

*This must be true since it is told that she needs $5 for lunch

*This is because the perm costs twice as much as the hair cut
Our new/updated equation is:

This is much easier to solve, let's rearrange and solve for 'p':



Therefore the perm costs $36
I hope this helps! Let me know if you have any further questions.
Let's look over the meaning of each option:
Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.
Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.
Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.
Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.
TL;DR: The answer is Socialism.
Well, don't you already have the t value ,-7.
Here is the set up:
x
x + 2
x + 4
x^2 + (x + 2) + (x + 4)^2 = 170
Take it from here.
