In general, the graph of f(x-h) will shift the graph of f(x) to the RIGHT h units. In general, the graph of f(x+h) will shift the graph of f(x) to the LEFT h units. In general, the graph of f(x) + k will shift the graph of f(x)  UP k units. In general, the graph of f(x)...

Your question may be to complete the square to solve for x? If that is the case, here is how you would go about doing that: To complete the square on the left side of the equation, you want to get a form of (x + a)2 on the left side.  To do that, you want to get a form of...

Just to clarify: Do you want to graph the following function? : g(x) = -√(x+2) + 2   where the (x+2) is the radicand (under the radical)   Do you know how to graph y = -√x? If so, do you know how the (x+2) changes the graph of  y = -√x ? Then,...

Well, the area of a rectangle is the length of the base times the length of the height: A= bh Since a square is a special type of rectangle that has 4 sides equal in length, the area is:  A = s*s or A = s2 where s is the length of one of the sides of the square. So, you have...

Do you mean 2 3√(128x4)  -  2*6 3√(54x) ?   It looks like your problem may really involve cube roots, not square roots. So, this is 2 times the cube root of the whole term (128x4) under the radical minus 2 times the cube root of the whole term (54x)  under the radical...

Since this is all multiplication and division, (no addition or subtraction), you can simplify like variable parts. You will need to use the fact that   am    =     am-n    ( for a not = 0)                         ...

Using the addition method, you could first multiply one equation by -1 then add to eliminate the x variables.  Let's multiply the second equation by -1 to give us: 4x   +  13y  =  40 -4x  +  (-3y) =  40   adding gives us           ...

First, think about what you did to figure out the first answer when the number of kilowatt hours was 300. C, the cost of usage, is what you found, when you used 300 as your kilowatt hours. So, you multiplied 8.77 by 300 and added 7.57 So,  C  =       ...

To solve a system of linear equations by graphing, you will need to graph both lines. The 3 possible solutions as mentioned in the problem are: one solution, no solution, or an infinite number of solutions.  When you graph the 2 lines, you will have one of 3 different possibilities. ...
