Answer:
1, 6, 15, 20, 15, 6, 1
Step-by-step explanation:
The binomial expansion of (p + q)⁶ gives 1, 6, 15, 20, 15, 6, 1.
There is always one more extra term for each power;
(p + q)⁰ = 1
(p + q)¹ = 1 1
(p + q)² = 1 2 1
(p + q)³ = 1 3 3 1
(p + q)⁴ = 1 4 6 4 1
(p + q)⁵ = 1 5 10 10 5 1
(p + q)⁶ = 1 6 15 20 15 6 1
The above is a paschal triangle and which shows the coefficients of the expanded terms to their power.
Answer:
(4, 3 )
Step-by-step explanation:
Given a system of equations graphically, then the solution is at the point of intersection of the 2 lines.
The lines intersect at (4, 3 ) ← solution
Answer: 15 minutes is spent on reading
Step-by-step explanation:
1 hour = 60 minutes
Jeny spends 3/5th texting
= 3/5 x 60 = 36 minutes
Remaining = 60 - 36 = 24 minutes
3/8 on brushing and pyjamas
= 3/8 x 24 = 9 minutes
Remaining time is 60-36-9 = 15
Well if you’re looking for y then
x=4y + 7
-4y
x-4y=7
-x. -x
-4y=-x+7
_______
-4. -4. -4
y= 4x - 7/4
i’m pretty sure :)
