Describe how to create the graph of the direct-variation relationship "y varies directly with x where y=-8.4 when x=4 ."

Mathematics

Lyrx [107]1 year ago

Answer:

Plot the graph of y=2.1x.

Explanation:

If y varies directly as x, we have the equation of variation as:

\begin{gathered} y=kx \\ k\text{ is the  constant of proportion} \end{gathered}

When x=-4 and y=-8.4

\begin{gathered} -8.4=-4k \\ k=-\frac{8.4}{-4} \\ k=2.1 \end{gathered}

Substituting k back into the equation above, we have:

y=2.1x

So, to create the required graph, simply plot the graph of y=2.1x.

Hector is solving an equation with variables on both sides, and his work is shown below. Explain Hector mistake in his work, and
Liono4ka [1.6K]

Answer:

  • x = 22.8

Step-by-step explanation:

<u>Solution of the given equation</u>

  • -124 + 4 7/8x = -10 - 1/8x
  • 4 7/8x + 1/8x = -10 + 124          ⇒ added 1/8x + 124 to both sides
  • 5x = 114
  • x = 114/5
  • x = 22.8

<u>Hector's mistakes</u>

  • 4 7/8x on left hand side becomes 4 6/8x as 1/8x was subtracted
  • -10 becomes -9 on right hand side for no reason

Answer:

The dominant economic systems of the modern era are capitalism and socialism, and there have been many variations of each system across the globe. Countries have switched systems as their rulers and economic fortunes have changed. For example, Russia has been transitioning to a market-based economy since the fall of communism in that region of the world. Vietnam, where the economy was devastated by the Vietnam War, restructured to a state-run economy in response, and more recently has been moving toward a socialist-style market economy. In the past, other economic systems reflected the societies that formed them. Many of these earlier systems lasted centuries. These changes in economies raise many questions for sociologists. What are these older economic systems? How did they develop? Why did they fade away? What are the similarities and differences between older economic systems and modern ones?
