Welldone to everyone
a friend of mine scored 207 and wanna study computer science,what are his chances

generally rise of 10°C.... of the temperature of a reaction system,..... the reaction rate

A. increases
B. doubles
C. subsides
D. drops

Eben331:
A...As the temperature increases, the rate of reaction increases.

TeflonBlixx:


For every 10 degree increase in temperature, the rate of reaction doubles. . B

Eben331:

Pls is true dat ui uses negative marking in putme? I heard it is advisable to leave question you don't know the answer to unshaded than shading it. When you wrote yours last year, did you answer all the questions or there are some questions you didn't answer? Pls I need clarifications on these.

Pes13:


Shade Everything, nothing like negative marking.
I can tell you this. Last year, after my Putme, I remembered at least 14 questions I got wrong which was confirmed by my textbook. I was still able to score 80%. It would have been lower than that if there was negative marking.

Mathematics

1. If the equations ax + by = -4 and bx + ay = 1 are satisfied by x= 1, y = 2, find the value of a and b.

2. The line whose equation is ax + by = 7 passes through the points with coordinates (-2, -1) and (-1, -3). Find the values of a and b. [Hint: substitute the given values of x and y to obtain twi simultaneous equations.]

3. Show that the equations ax + by = c and px + qy = r will have no solution if aq = bp.

pls show your workings

x^2-xy-6y^2=0,multiplying 1st and last term gives me -6(xy)^2.so factors are 2xy and-3xy...substituting these values for -xy, I got x2+2xy-3xy-6y2=0...factorizing gives me (x-3y)(x+2y)=0...going for x-3y=0,x=3y and x/y gives me 3...I hope I am right...

Samsonyte:
close to the answer sir
The equation is a quadratic in two variables x and y Factorise the left hand side: x^2 - xy - 6y^2 = 0 (x^2 - 3xy)+ (2xy - 6y^2) = 0 x(x - 3y) +2y(x - 3y) = 0 (x + 2y)(x - 3y) = 0 From (i) x = 3y i.e x/y = 3 and from (ii) x = -2y i.e. x/y = -2 The values of x/y are 3 and -2.
