It’s because 2/3 of 30 miles in 3/4 hours is the same as 20 miles in 1/2 hour.
Proof:
30/1x2/3
60/3 = 20
3/4x2/3
6/12 = 1/2

Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10? –10, –12, –14, –16, –18, ... –2, 8, 18, 28, 38, .

Answer:
D
Step-by-step explanation:
Given
f(n + 1) = f(n) - 2 with f(1) = 10
To generate the sequence substitute values for n into the recursive formula.
f(1) = 10
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
f(4) = f(3) - 2 = 6 - 2 = 4
f(5) = f(4) - 2 = 4 - 2 = 2
The first 5 terms are 10, 8, 6, 4, 2
P = 2w + 2h
factorise
P = 2 (w + h)
divide both sides by the coefficient of w + h
P ÷ 2 = 2 (w + h) ÷ 2
P/2 = w + h
make w the subject of the formula
w = h - p/2

Answer:
2. An absolute.value cannot be negative
Step-by-step explanation:
I.I'll explain it short why absolute.value cannot be negative
Given |4x - 7| = -1
4x = -1 + 7
4x = 6
x = 3/2
II. Prove by x = 3/2
|4(
) - 7| = -1
|2(3) - 7| = -1
|6 - 7| = -1
| -1 | = -1
1 = -1 false, not true
III. Absolute value is came from 
As you knew square root value cannot be negative
So absolute.value cannot be negative.
Ask me for anything.
