That variation results in Qxa4+
as in:
1. Qb5 Rxc5
2. Qd7+ Kc4
3. Qxa4+ (checkmate)
If you mean T to mean the rook takes c5 then:
1. Qb5 Rxc5
2. Qd7+ Kxe5
3. Ng4+ (checkmate)
Or if you mean the knight takes c5 then:
1. Qb5 Nxc5
2. Ng4 c1=Q
3. e3+ (checkmate)
I couldn't have solved it myself, but my chess computer can mate in 3 against any defence.
It gives the main line as:
1. Qb5 d1Q
2. Nxb3 axb3
3. Qd5+ (checkmate)
Hi Mandy. Glad to hear that you are feeling better. Yes I will be logging on at the weekend.
Looks like we need to teach you about negative numbers in coordinates and how to plot them.
Bye for now.
Incidentally I have got a screen picture of the graph using GeoGebra so if you are really stuck I could email it to you
or even post it on here. However it would be better for you if you manage to plot the final point without that help.
First of all well done for getting the four that you have done correctly  they all look fine to me.
Now with the (3,4) one you might just about be able to squeeze it on to your graph paper if you
extend the axes the other way like this:
i
i
i (The other four points are in this area)
i
0
3 


x 4
You then need to go three spaces to the left of the point where the lines cross and four spaces
down. Remembering to make the spaces equal between each point on your axes.
Obviously my sketch above is only a rough guide in plain text  you will be able to do the
graph properly on your paper. I think that you just about have space to the left of your point
at which the axes cross (which is the bottom left on your graph point (0,0) ).
Okay
Mandy, can I assume by the fact that you have not done it that you are stuck on the exercise or are you just busy?
Ok I am improvising here:
Plot the following coordinates on some graph paper:
A (2,6)
B (3,4)
C (5,3)
D (6,2)
E (3, 4)
Put the letter next to each point to show which is which, and please upload a snapshot of the graph paper that you use so that we can see if they are correct.
How well do you think you are getting on with coordinates?
If you were given a set of coordinates to plot do you think you would do it correctly?
There was a link to a website http://www.mathplayground.com/locate_aliens.html
How did you get on with that?
hi steve b mandy here how are you? how do you think i am doing and do you think i should do a home maths course yet or nor?
I am fine thankyou. I think that you are doing well studying via the maths forum with the help of Chris and Bob, but remember that distance learning courses will charge for their service so I am tempted to say that you should not commit your self to any study you have to pay for because you have a tendency to start doing something and then stop abruptly and lose momentum and in any case the level you are studying at is, while good to see, a somewhat basic level and below the level of most maths courses.
One thing I must say that is positive is that you have learnt a skill that I can't do namely to add graphics to a post!
I suppose I could learn how to do it, but since you have been getting on so well I don't want to interfere with other maths teachers.
Hi Steveb mandy here hope you are ok? have you seen what I have been doing could you send me a message back on here and let me know what you think then please?
Mandy, you are doing very well keep up the good work. I am glad to see that Chris has been helping you and Bob Bundy is teaching you as well.
There may be an element of "too many cooks spoil the broth" if I try to teach you at the same time, but I am happy to jump in if you think it would help.
Bar charts, pie charts and line graphs are quite tricky to teach via a forum because a lot of pictures are needed. In fact you are using a new method of displaying graphics on this forum that I have not got any experience of yet.
One thing that I have thought of is drawing graphs using a spreadsheet and it could be used as a means of creating some exercises. The trouble with that is that spreadsheet graphs may be a little too easy to create and if you are preparing for any form of exam you are expected to draw the graphs yourself. However sometimes the graph is already drawn for you and you have to answer questions about it.
I see that you are doing questions involving negatives and positives: Remember two negatives cancel to make a positive in maths so ((1)) = 1 (minus minus 1 equals plus one).
:)
It was question 5 from the bar charts page.
Bob has given his apologies that he is not able to do MIF at the moment.
He has said don't worry if you can't do the screenshots Mandy.
He said can Chris please make up 3 more questions like the one Mandy got wrong.
You could try the questions at the bottom of the pages of the maths is fun teaching website on graphs. There are for instance 10 questions on bar graphs and 10 questions on line graphs.
Hi Mandy, what do you mean by the word "graphics" ?
Do you mean graphs ?
Here are two links to the maths is fun teaching website on graphs:
http://www.mathsisfun.com/data/bargraphs.html
http://www.mathsisfun.com/data/linegraphs.html
Graphics is used as a term in computing to refer to pictures, images, animation etc.
I have sent you a spreadsheet of this, but it went through to your mobile. I will try sending it again if you like, but you can always just use the post above. Are you okay ?
Here is another set of fractions, decimals and percentages, I will send you a spreadsheet version of these:

Since Bob joined in with this you have improved, but I don't want to get too mad with excitement that you could pass GCSE. I am hopeful that in terms of everyday maths you are doing well and better than before. One thing we did think about is that maybe you should avoid doing the full GCSE and just try to benefit from the forum engagement to get you improved. To get a 'C' at GCSE for you is a tall order. I personally would recommend going full steam ahead towards learning basic maths.
Just for the record there was one silly mistake in my answers that I sent to you where I had made a mistake with 0.12 and converting this to a fraction.
The correct answer is in fact (3/25) as a fraction and not (6/25) so sorry about that.
The working for this might go as follows:
0.12 = 12 /100
12 /100 = 6 / 50
6 / 50 = 3 / 25
I wrote those out in a hurry.
The latest set of questions are as follows:
Fraction Decimal Percentage
4/5  
1/12  
6/7  
1/3  
 0.65 
 0.16 
 0.55 
  60%
  40%
  20%
  80%
My apologies by the way about 1/12, 6/7 and 1/3
I realise that these need rounding.
I should try to round them to 2 decimal places if you can.
See if you can format the text in the spreadsheet,
but don't worry if you can't.
