Answer:
I haven't learn this yet but you can maybe ask desmos that app is helpful maybe it can help with your question.
Combined like terms than subtract with system of equations
Answer:
4x² + 13x + 3 and 2x² - 3x - 17
Step-by-step explanation:
(a)
f(x) + g(x)
= 3x² + 5x - 7 + x² + 8x + 10 ← collect like terms
= 4x² + 13x + 3
(b)
f(x) - g(x)
= 3x² + 5x - 7 - (x² + 8x + 10)
= 3x² + 5x - 7 - x² - 8x - 10 ← collect like terms
= 2x² - 3x - 17
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
Answer:
Volume = 52.5³
Step-by-step explanation:
Volume = Length * Width * Height
Substitute
Volume = 7/2 * 5/2 * 3/2
Volume = 105/2³
Simplify
Volume = 52.5³
