Answer:
d = 6 , a₁ = - 6 and a₁₀ = 48
Step-by-step explanation:
The nth term of an arithmetic progression is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₃ = 6 and a₇ = 30 , then
a₁ + 2d = 6 → (1)
a₁ + 6d = 30 → (2)
Subtract (2) from (1) term by term to eliminate a₁
4d = 24 ( divide both sides by 4 )
d = 6
Substitute d = 6 into (1)
a₁ + 2(6) = 6
a₁ + 12 = 6 ( subtract 12 from both sides )
a₁ = - 6
Then
a₁₀ = - 6 + (9 × 6) = - 6 + 54 = 48

Answer:
y = 2x + 12 is your answer.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other.
First, distribute 2 to all terms within the parenthesis.
y - 6 = 2(x + 3)
y - 6 = 2x + 6
Next, isolate the variable y. Add 6 to both sides.
y - 6 (+6) = 2x + 6 (+6)
y = 2x + 6 + 6
y = 2x + 12
y = 2x + 12 is your answer.
