A) (32x² + 24x +12) / 16. Notice that the GCD of 32, 24 and 12 is 4
then let's factorize:
4(8x² + 6x + 3) / 16. Now simplify numerator & denominator by 4
Hence a) = (8x² + 6x + 3) / 4
b) 35/(42x² - 49x +21); the GCD (of denominator) of 42, 49 and 21 is 7
then let's factorize:
35/[7(6x² -7x +3); Notice that 35 = 7.5 ; 7.5/ 7(6x²-7x+3)
Now simplify numerator & denominator by 7
Hence b)= 5/(6x²-7x+3)
Now do the same for the others.
Answer:
x - y = -1 ....... 1
3x + 2y = 22 ........ 2
Make x the subject in the first equation
x = -1+y
Substitute this into the second equation
3(-1+y) + 2y = 22
-3 + 3y + 2y = 22
5y = 25
Divide both sides by 5
y = 5
Substitute y = 5 into x = -1+y
x = -1+5
x = 4
x = 4 , y = 5
Hope this helps
The value of y is 29
Since x=4, put 4 in 9x
y = 9(4) - 7
y = 36 - 7
y = 29
Answer:
A
Step-by-step explanation:
The end behaviour as x gets larger and positive ( right- hand end )or larger and negative ( left- hand end )is determined by the term of the greatest degree.
For p(x) that is 4
, with
• Even degree (8) and positive leading coefficient (4), then
as x → ∞ , p(x) → ∞ and
as x → - ∞ , p(x) → ∞
If you are multiplying by 100, the decimal will move 2 places to the right.
It moves to the right when multiplying because the number is getting greater, and there are 2 zeroes in 100 so it moves twice.
