Need more information. Are you solving for x or for y? is there a second equation? Are you graphing?

Total right away tells me we are adding.   To Find distance, you multiply speed times time. So Jethro's distance is 3 x 2 and Randy's distance is 4 x 3.  Then we add these.

10?   Unless I am mistaken, it is 1 second per strike.    10 strikes, 10 seconds.

This is a similarity problem. It basically is saying 1:30 means for every 1 cm we have, you get 30 cm.     This is easier than other problems since it is 1:30  and not weird like 5:9.     So we can basically multiply each of the given dimensions by 30, and...

(Sale Price) x  (Sales tax rate) = tax   You are missing the Sale price so we will use P in place of that.   P x 7.5% = 9.75     Rewrite 7.5% as a decimal.  0.075   P x 0.075 = 9.75   Since we are solving for P,...

Compound interest uses the same formula all the time.     Future amount = beginning amount *( 1+interst rate)number of coumpounds   Written with variable is is  F = P(1+i)n   Depending on the problem you are usually given 3 out...

If there are 16 members an 2 are male, then how many are female? You should be able to find this number.   Then take the number you found and make that a numerator, make the denominator the number of boys. Then reduce.   Example:  Let's say there are 20 members on...

"Half of 36" is the same as (36 divided by 2). "Giving 4 away" is the same as (subtracting the new number by 4).   So start with 36, then divide by 2, then subtract 4.     If you can type this question then you can calculate the answer.

Let's start with the numerator(top). 27-2/3 means the cubed root of 27, then squared, then moved to the denominator because the exponent is negative.   The cubed root of 27 is 3. squared it becomes 9. and the negative exponent makes it 1/9. (the 1 appears because something...

I am getting f'(x) = 2xe^(x2+1).   Is that what you got?   Next you will have to use product rule.  (Derivative of 2x) times e^(x2+1)  + 2x times (Derivative of e^(x2+1))   I got f''(x) = 2e^(x2+1) + 4x2e^(x2+1)   Notice...

x = r cosθ    y = r sinθ     r = -3 θ = 120o   Plug them in a calculator and then write your answer as ( x, y).   If you are not able to use a calculator, then you will need to graph the line which will end up in Quadrant 4. If you create...

It is not very clear on who is getting what amounts. I am going to assume that the sales associates company gets 5.5% and 6.5%, and then the sales associate gets 25% of that.   First, half of 65000 is 32,500. So the company will earn 5.5% of 32,500 and 6.5% of the other 32,000.     5...

I just answered this same problem for another student. Please check the board. It is close to your post.

Let's review what this is saying and let's pretend we are talking about rats or some small animal that doesn't live too many years.    It says that at age 0, there were 100 rats, and at age 1 there were only 65 rats. That means that 35 rats died when they were 0 years old or another...

Compounded interest uses the formula     Final value = Present value *  (1 + interest /#of compound per year) #of total compounds     Although we don't know the present value, we can still create the equation and work backwards.   22,000...

\$150 for 10 months means he paid 150+150+150+... ten times. or 10 x 150 = 1500. This is the amount the debt has decreased. what amount did the debt start at if he has paid this much so far. His original debt must be higher 1500 higher than 6900.  I think you can take it from here...

Hello, unfortunately trig identities take time and depend on the problem. Trig identities are like proofs where there is no one method that will solve all of them or even the next one. Only time and a lot of practice will help you understand it.    Here are some pointers I give...

Create an upside down right triangle with 18.8o in the upper left, and 90o in the upper right.     The edge on the right side is the altitude, 1640.                                      ...

P(K,K) = (4/52) *(4/52) = 1/169   P(D, 8) = (13/52) * (4/52) = 1/52     P(4S, KD) = (1/52)*(1/51) = 1/2652   NOTE: denominator must decrease since there is one less card in the deck.   P(K, Q) = (4/52) * (4/51) = 4/663
