Everybody is picking c . Yes c is correct.

But the answer actually is -153/42. How do you put it in a mixed fraction?

-153/42= - 51/14 (Dividing both d numerator and denominator by 3)

= - 3 9/14 ans

In a certain coordinate system {O, e₁, e₂, e₃}, where eᵢ, i ∈ {1, 2,3,4} denotes unit vectors and O the origin.
Three vertices of a parallelogram ABCD are given as A(0, 1, -1) B(1, 0, 2) and C(2, 3, 0).

Find the coordinates of the point D.

Hi, great minds. Please I need help with this assignment.

find the positive value of C if the expression (2C+3)y² -6y+4-c is perfect square

Hi, great minds. Please I need help with this assignment.

find the positive value of C if the expression (2C+3)y² -6y+4-c is perfect square

(2C+3)y² - 6y + (4-C),
for a perfect square, b² = 4ac ........*
a = 2C+3, b = -6, and c = 4-C,

sub. these in eqn *;
b² = 4ac
(-6)² = 4 × (2C+3) × (4-C),
36 = 4(2C+3)(4-C),
36 = 4(8C -2C² +12 - 3C),
36 = 4(12 + 5C - 2C²),
36 = 48 + 20C - 8C²,
8C² - 20C - 48 + 36 = 0,
8C² - 20C - 12 = 0,
divide through by 4;
2C² - 5C - 3 = 0 .........**

solving eqn ** quadratically;
C = 3 or -½

Thank you so much, I really appreciate.

OK

Please can someone help me with this in the picture. Solve using logarithm table. My problem is the subtraction and addition signs in the questions.

Please teachers, who can share me soft copy of first term question papers for senior secondary 1, 2 and 3. Email address is paulmarkino@gmail.com or WhatsApp me on 08032334579

dont be a lazy teacher. type the questions yourself

Boss am not a teacher. I just want to be able to solve such questions. I don't want to make it like I set up the question.

Ok bro. Nice one then . I teach A level and Junior school 3, would have sent seniors for you if I had it .

b) Log (p - q)/√13

P.S: If possible solutions should be hand written snapped and uploaded for better comprehension
Thanks.

thanks in advance.

The pairs (x, y) = (2, 3), (3, 2) are indeed solutions to the system. It remains to show that they're the only solutions to the system.
To do this, it is enough to prove that if a solution to the above system exists, then they must be positive integers. Indeed, from x + y = 5. We deduce that the pair (x, y) must be rational numbers. On the other hand, from x² + x^y = 17, we get x^y = 17 -x² from this we deduce that x and y must be positive integers for it that were not the case, the number x^y is irrational while 17 - x² would be rational and equality cannot hold. And this completes the proof.

For everyone.
