Please refer to the manual and check if the chosen MODE is the correct one required to process the equation or the commutation required or else this wont work.
Check to see the different modes and study on how to apply them to the said equation.

You want to rent a jet ski it would cost 50.00 for a deposit plus 35.00 per hour how long can you rent the jet ski if you have 450 budgeted for the rental fee

$450.00 divided by $35.00=12 hours with $30.00 left to pay the sales tax. $35.00 x 12hrs =$420.00. The deposit can be figured in the available cash as when you return the jetski you will be refunded the $50.00 deposit giving you the whole $450.00 to use to pay the bill.

What is y+x = -4 , graph and find the y-intercept ?

Hey! The standard equation of a straight line is y=mx+b (wherein x&y are the coordinates, m is the slope of the line and, b is the y-intercept). Re-arranging your equation to follow the standard equation, you'll have y= -x - 4 or y=(-1)x + (-4).

To plot the equation, try substituting a number to the (x) coordinate to get the value of the (y) coordinate:
If x=0, y= -4
If x=1, y= -5
If x=2, y= -6
If x=3, y= -7
Assuming you know how to plot these coordinates, you now have a graph of the equation. Hope I answered your query. Thank you.

Examples of homogeneous differential equation

Hi janeth sabay,


Have a good day!!


Here is your needed example for Homogenous differential equation:


The equation 49e8abf8a1c5be91fadbf33a5405bdc3.gif is said to be homogeneous if P and Q are homogeneous functions of x and y of the same degree.


We can test to see whether this first order equation is homogeneous by substituting 21fe29cd49ecbd3abe2ae6373e89eab6.gif . If the result is in the form f(v)i.e. all the x's are canceled then the test is satisfied and the equation is Homogeneous.

Example 1:19c981882c1f9b05fadf586b56a931bc.gif(2)


There are no terms in x on the right hand side and the equation is Homogereous.Example 2:72f80f87eb510a9e0fd81c423b3faa55.gif(4)


So the original equation is not homogeneous.Methods Of Solution.

A solution can be found by putting y = vx on both sides of the equation:-

Example 3:


Putting y - vx

Since y is a function of x so is v




Separating the variables





Substituting (12) in equation (10)

In complex number mode, how to get out?

"Is there anything that I can do about this to stop my answers being complex numbers when solving cubic equations?"
You are making an assumption that is unwarranted.Namely that a cubic equation must necessarily have 3 real roots. This is not the case.

Let your equation be
If coefficients are complex you should expect some complex roots. Right?
If the coefficients are REAL then depending on the discriminant
you can have three cases
DELTA positive : three distinct real roots
DELTA=0 , the equation has a multiple root and all roots are REAL
DELTA negative: the equation has ONE real root and 2 complex roots that are complex conjugate of each other.

It suffices to look at the Tartaglia/Cardano expressions of the roots to know that more often than not there is going to be complex roots.

How do i put and x or y or m into and equation

Rename your variable (unknown) X, because the calculator takes X as the default unknown. It will ask you "Solve for X?"
the 7, the second minus sign, 3 and 11 use the relevant keys.
For the first minus sign use the negation key or change sign (-)
For the variable X, examine the calculator keys on the row where the parentheses are. To the right corner of the key area there is a symbol in the same color as the ALPHA key. I believe the X is under the right parenthesis, or thereby.
To enter the X variable you press [ALPHA][ )]. To enter the = sign, you press [ALPHA] [CALC].

To execute the solve command, press [SHIFT] [CALC] and you will be prompted " Solve for X?"

Look at these equations 11=6+a a+7=10+b use both equations to work out the value of b??

1st equation:

Everything the you do to one side of the equals sign in an equation, you have to do to the other.  So let's subtract 6:


The second equation:


Now we know from the first equation that a= 5, so let's put that in:


Or, simplifying:


Let's take away 10 from both sides:


So your answer is:  b=2

Solver not working properly

try a simple equation like x^2-1 which should come out with x = 1,-1

no sign change would indicate that the graph of the curve never crosses the x axis, if you graphed the above equation and calculated the zeros, it would come out with -1, 1 which it should, but if you put in x^2+1, the graph would never cross and therefore have no sign change from pos to neg or vice versa, the left-rt are the left and right bounds or the lower and upper bounds which was corrected in later calculators, Please let me know the outcome of graphing both of the above equations and then putting them in the solver. you could also use the quadratic equation to prove the answers if you liked, hope this helps
