Answer is A)
1km=1000metres
15km=15000 metres
15000/600=25
25-1=24 (minus the last one)
hope this helps :)
The square root of 13 rounded to the nearest tenth is 3.6, so you would plot this somewhere in between 3 and 4 on a number line.
Y = 4x + 3 ---------(1)
y = -x - 2 ---------(2)
Subtract (2) from (1), you get
0 = 5x + 5
⇒ 5x + 5 = 0
⇒ 5x = -5
⇒ x = -5/5 = -1
y = -(-1) - 2 = -1
Answer is (-1,-1)
Either you can use distributive property or you can add up the numbers in the brackets.
Hopefully that helped! :)
