Answer: x ≥ -1
<u>Step-by-step explanation:</u>
4(2x - 3) ≥ 4(x - 4)
8x - 12 ≥ 4x - 16 <em>distributed 4 into 2x - 3</em>
4x - 12 ≥ -16 <em>subtracted 4x from both sides</em>
4x ≥ -4 <em>added 12 to both sides</em>
x ≥ -1 <em>divided both sides by 4</em>
Graph: -1 -------------→

Answer:
yes
Step-by-step explanation:
Markup based on selling price
Answer:
Step-by-step explanation:
So we just want to get y by itself
2x - 4y = 8
4y = 2x - 8
y = (2/4)x - 2
y = (1/2)x - 2
In this form the y intercept and slope are easy to see. the slope is m and y intercept is b.
slope = 1/2
y intercept = -2
Answer:
Step-by-step explanation:
Economics is a branch of social science and it deals with more of observations, theories, laws, deductions and construction of abstracts model.
So, to do all of these, economists need to be good at mathematics to approach some of these abstracts model.
Like all other scientist, economists also do hypothesis to allow them study the economy growth and help them construct a model that solve this goals these requires a lot of mathematical models and abstract reasoning. They usually employ mathematical and graphical models and analysis to solve the economic issue e.g. demand and supply curves analysis
Economic models usually employ graphical and mathematical analysis to help explain and illustrate such economic processes.
All of these makes economic very hard to study. So to study economics, you need to be good at mathematics
