Answer:
3, 1, - 1, - 3 and - 15
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is
a₁ = 5 - 2(1) = 5 - 2 = 3
a₂ = 5 - 2(2) = 5 - 4 = 1
a₃ = 5 - 2(3) = 5 - 6 = - 1
a₄ = 5 - 2(4) = 5 - 8 = - 3
The first 4 terms are 3, 1, - 1, - 3
For 10th term substitute n = 10 into the rule
a₁₀ = 5 - 2(10) = 5 - 20 = - 15

Answer:
[tex]h^{-1}[/tex] (x) = 2x - 6
Step-by-step explanation:
let y = h(x) and rearrange making x the subject
y = [tex]\frac{1}{2}[/tex] x + 3 ( multiply through by 2 to clear the fraction )
2y = x + 6 ( subtract 6 from both sides )
2y - 6 = x
Change y back into terms of x with x = [tex]h^{-1}[/tex] (x)
[tex]h^{-1}[/tex] (x) = 2x - 6

Write a function equation that represents a line that contains the two points (-3, 5) and (2, 10).
Step-by-step explanation:
1. 1st of all calculate the gradient
( - 3, 5) ( 2, 10)
Gradient = (10 - 5) / ( 2--3)
= 1
2. Then find the eq
Y = mx + c
Where m is the gradient
y= 1x + c
Now replace any 2 coordinates from above in the eq.
For ex I'm taking (2, 10)
Y = 1x + c
In the coordinate, x = 2 and y =10
By replacing this in the eq, I will find c
10 = 1(2) + c
2 + c = 10
c = 10 - 2
= 8
So the eq is y = x + 8 ⬅️
