I wish I could explain how to do these, but I can recommend Math-way. You can type the equations in and it with simplify it for you. It will even show you the steps, but you have to pay fro that part, but at least it will give you the answer.
Answer:
You can do this. It's actually pretty simple
Step-by-step explanation:
You are given 3 hours. and you re told 5 kph or kilometres per hours.
3 replaces the x variable. You can take it from there and for sure you'll get the answer you want for y
Answer:
12 =x
Step-by-step explanation:
We can use proportions to solve
6 x
---- = -------
10 10+10
Using cross products
6 ( 10+10) = x*10
6*20 = 10x
120 = 10x
Divide by 10
120/10 = x
12 =x
All the x coordinated are 0, 5, -3, and -4.
0, 5, and -3 are all greater than or equal to -3
