Someone help... pleaseee
frutty [35]

Answer:

2x + 8

Step-by-step explanation:

Don't worry, this is simple! Add up the common terms.

For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.

So combine the x terms: 2x

And the numerical terms: 8

Combine 2x and positive 8.

2x + 8

Help me do the ones marked in red.
Dmitrij [34]

Answer:

  2. "two thirds of the fourth power of <em>r</em>"

  4.  n + 14

  6.  7 +11n

  8.  (2/5)n^2

__

  7.  28

  8.  1/5

Step-by-step explanation:

2. "two thirds of the fourth power of <em>r</em>"

__

4. "sum" means the listed items are added. You can use any convenient variable to represent "a number." I often use <em>n</em> for <em>n</em><em>umber</em>.

  n + 14

__

6. "7 more than" means 7 is added to whatever follows. "11 times a number" means the number is multiplied by 11.

  7 + 11n

__

8. "of" means "times". The square of a number is that number to the power of 2.

  (2/5)n^2

__

7 & 8 (evaluation). Your calculator can do this. (If not, get one that can.) Note that parentheses are needed around numerators and denominators and anything else that must be treated as a single value.

A Bernoulli differential equation is one of the form dxdy+P(x)y=Q(x)yn Observe that, if n=0 or 1, the Bernoulli equation is line
aleksandr82 [10.1K]

It's unclear whether the ODE is

xy'+y=4xy^2

or

xy+y'=4xy^2

If the first case, then divide through both sides by y^2 to get

xy^{-2}y'+y^{-1}=4x

then substitute z=y^{-1}, so that z'=-y^{-2}y'. Then

-xz'+z=4x\implies-\dfrac1xz'+\dfrac1{x^2}z=\left(-\dfrac1xz\right)'=\dfrac4x

\implies-\dfrac1xz=\displaystyle\int\frac4x\,\mathrm dx

\implies z=-4x\ln|x|+Cx

\implies\boxed{y=\dfrac1{Cx-4x\ln|x|}}

If the second, then dividing through by y^2 gives

xy^{-1}+y^{-2}y'=4x

The same substitution as before gives

xz-z'=4x\implies e^{-x^2/2}z'-xe^{-x^2/2}z=\left(e^{-x^2/2}z\right)'=-4xe^{-x^2/2}

\implies e^{-x^2/2}z=\displaystyle-4\int xe^{-x^2/2}\,\mathrm dx

\implies z=4+Ce^{x^2/2}

\implies\boxed{y=\dfrac1{4+Ce^{x^2/2}}}

The Massachusetts Department of Employment and Training predicted that there will be 21% more jobs for computer programmers in M
vova2212 [387]

Answer:

19,324

Step-by-step explanation:

The original amount is 100% of the original amount since 100% means a whole amount.

A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.

Now we calculate 121% of 15,970.

To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.

121% of 15,970 =

= 121% * 15,970

= 1.21 * 15,970

= 19,323.7

19,324
