Answer:
3rd option
Step-by-step explanation:
( factorise numerator and denominator )
3x² - 3 ← factor out 3 from each term
= 3(x² - 1²) ← x² - 1 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
x² - 1
= x² - 1²
= (x - 1)(x + 1) , then
3x² - 3 = 3²(x - 1)(x + 1) ← in factored form
--------------------------------
x² - 5x + 4
consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)
the factors are - 1 and - 4 , since
- 1 × - 4 = + 4 and - 1 - 4 = - 5 , then
x² - 5x + 4 = (x - 1)(x - 4)
then
= 
← in factored form
Answer:
Step-by-step explanation:
lets pick 2 points on the line....(6,5) and (10,3)
slope = (y2 - y1) / (x2 - x1)
(6,5)....x1 = 6 and y1 = 5
(10,3)....x2 = 10 and y2 = 3
now we sub
slope = (3 - 5) / (10 - 6) = -2/4 = -1/2
now we use y = mx + b
slope(m) = -1/2
u can use either of ur points...I will use (6,5)...x = 6 and y = 5
now we sub and find b, the y int
5 = -1/2(6) + b
5 = -3 + b
5 + 3 = b
8 = b
so ur equation is : y = -1/2x + 8 <===
Step-by-step explanation:
3/4 of 12
3/4 × 12 = 9
6/7 of 49
6/7 × 49 = 42
2/3 × 27 = 18
3/8 x 16 = 6
