Answer:
5, 9, 13, 17, 21, .....
Step-by-step explanation:
To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule
a₁ = 4(1) + 1 = 4 + 1 = 5
a₂ = 4(2) + 1 = 8 + 1 = 9
a₃ = 4(3) + 1 = 12 + 1 = 13
a₄ = 4(4) + 1 = 16 + 1 = 17
a₅ = 4(5) + 1 = 20 + 1 = 21
X = 5 - 3y
x = 2y - 10
5 - 3y = 2y - 10
<u> + 3y + 3y </u>
5 = 5y - 10
<u>+ 10 + 10</u>
<u>15</u> = <u>5y</u>
5 5
3 = y
x = 2y - 10
x = 2(3) - 10
x = 6 - 10
x = -4
(x, y) = (-4, 3)
Answer:
y - 2x = 2
Step-by-step explanation:
2y - 4x = 4
2(y - 2x) = 4 | : 2
y - 2x = 2
