Solve the equation for y. 4.2x-1.4y=2.1

Mathematics

mr Goodwill [35]3 years ago
8 0

Subtract 2.1 from both sides:

4.2x-1.4y-2.1=0

Add 1.4y to both sides:

4.2x-2.1=1.4y

Of course, we can rewrite this as

1.4y=4.2x-2.1

Divide both sides by 1.4

y = \dfrac{4.2}{1.4}x - \dfrac{2.1}{1.4} = 3x - 1.5

Use the graph below to answer the question that follows:
seraphim [82]
Let's start with our parent function:

f(x) = sin x

One cycle on this graph occurs between 0 and 2π. Therefore, our b-value is one.

There is no vertical shift up. The sinusoidal axis is along y = 0.

The wave is not inverted, it starts at the origin and rises on both the y and x axis. Thus there is no negative value before the function.

The amplitude of the wave is 3. A normal sine wave rises to a maximum of 1, but this is multiplied by 3.

f(x) = 3 sin x

There are an infinite amount of equations that could be used to represent this graph, but this is perhaps the most intuitive.
