Answer:
5
Step-by-step explanation:
(3,8) (0,4)
X1 = 3 X2 = 0
Y1 = 8 Y2 = 4


Do what's in the parentheses so...
- 3-0= 3
- 8-4= 4
Now plug it in!

Now you are going to finish the parentheses so...
- (3)^2= 9
- (4)^2= 16
Plug that in so that you have this...

Add 9+16 to get...

Then you are going to find the number or numbers that make this a perfect square...

So 5 is your answer
I think the answer is 6 because 900/150= 6 and 6X150 is 900 :)
There are NO choices.
I know for TWO linear equations to have a unique solution they CANNOT be parallel.
Answer:
16 km/h ….. still water boat rate
4 km/h …. Current rate
Step-by-step explanation:
The speed of the boat supposed to be x km/h
The current rate is y km/h
(x + Y) * 3 = 60
(x – y) * 5 = 60
3x + 3y =60 ….. ①
5x – 5y = 60 ….. ②
① * 5 … 15x + 15y = 300 … ①’
② * 3 … 15x – 15y = 180 … ②’
①’- ②’ … 30y = 120
Y = 4 km/h …. Current rate
15x = 300 – 15*4 = 240
X = 16 km/h ….. still water boat rate
