Answer:
C. aₙ = 7 + (n-1)(-4)
Step-by-step explanation:
a₁ =7 a₂ = 7-4 = 3 a₃ = 3 - 4 = 7-4 -4 = 7- 4* ( 3-1) = -1
aₙ = 7 + (n-1)(-4)

Answer:
663
Step-by-step explanation:
ratio of Malay = 5
ratio of Indian= 4
ratio of Chinese= 8
Total number of Indian + Chinese= 468
Total ratio= 5+4+8= 17
Let the total number of students= X
Ratio of India= 4/17 × X=
Ratio of Chinese= 8/17 × X=
Addition of ratio of both India and Chinese=
4X/17 + 8X/17= 468
(4X +8X)/17 = 468
12X/17= 468
X= 663
Hence, total number of students is 663
Answer:
x^2 - 6x + 9
Step-by-step explanation:
(x-3)^2
(x-3)(x-3)
x^2 -3x -3x + 9
x^2 - 6x + 9
^2 means (x - 3) times itself twice.
(x - 3)(x - 3) multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)
Firsts (x* x) Outs (x*-3) Inners (-3 * x) Lasts (-3*-3)
xx -3x -3x +9 Combine like terms.
-3x -3x Adding/subtracting integers- same signs means you add
and keep the sign.
x^2 -6x + 9
Answer:
Step-by-step explanation: Subtract b from both sides to isolate mx :
y - b = mx + b - b
y - b = mx
STEP 2 :
Divide both sides by x in other to isolate x
(y - b) / m = mx / m
(y - b) /m = x
Therefore, making x the subject gives the final equation as : x = (y - b) /m
