<span>Correct answer is A.
Anything with a constant gradient is a linear function.
y = c
y = 0×x + c
k = 0 - constant gradient</span>
Answer:
2 km/h
Step-by-step explanation:
Let
Rate of river current = x km/h
Speed of Peter's boat = 4x km/h
He takes 15 km trip up (opposite direction)
His speed upstream = 4x - x
= 3x
His speed is 3x and distance is 15 km
Time = Distance / Speed
15/3x
= 5/x
And
Moving downstream (same direction)
Speed will be 4x + x = 5x
Distance = 15km,
speed = 5x
Time = Distance / Speed
= 15/5x
= 3/x
Total time take for trip = 4 hours
Total time take for trip = upstream + downstream
4 =5/x + 3/x
4 = 8/x
Cross product
4 * x = 8
x = 8/4
x = 2
Rate of river current = x km/h
= 2 km/h
My guess would be: 3 x(times) 500+80+4
Answer:
A.
Step-by-step explanation:
when you distribute it you keep the subtraction sign and have to multiply 6 by 50 and then 6 by 1
Answer:
The value of 
.
Step-by-step explanation:
Given:
We need to solve this equation.
Solution:
First combining equation having same denominators we get;
Now denominators are common so we will solve the numerators we get;
Now by cross multiplication we get;
Now Applying distributive property we get;
Now Combining the like terms we get;
Hence on solving we get the value of .
