Answer:

x+5-2x=2

5-x=2

Step-by-step explanation:

y = x + 5

y - 2x = 2

substituting y from the first equation into the second equation

We are given with first equation y = x + 5

We plug in x+5 for y in second equation

y - 2x = 2, Replace y with x+5

x+5-2x=2

combine like terms

x-2x is -x

5-x=2

find the exponential regression equation for the data points (-4, 0.75), (-2, 6), (3, 28), and (5, 162)
zubka84 [21]
<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM 

</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.

anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.

there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.

Estimate 25.65 + 13.23 + 6.35 by rounding each number to the nearest tenth.
sergij07 [2.7K]

Answer:

  • b. 25.7 + 13.2 + 6.4 = 45.3

Step-by-step explanation:

25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4

  • 25.65 + 13.23 + 6.35 =
  • 25.7 + 13.2 + 6.4 =
  • 45.3

Correct choice is b.

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.
