Answer:
1. x + y = 25
2. x - y = 7
3. x = 16, y = 9
Step-by-step explanation:
(x + y = 25) + (x - y = 7)
2x (the y cancels) = 32
32/2 = 16, x = 16
substitute x in either equation
16 + y = 25
y = 9
Answer:
im pretty sure the distance is across the y and x axis
Step-by-step explanation:
Answer:
the value of x° is 40° ..........
Find attached solution.
With Rough Work by the right hand side.
Note that when you carry out the division, you then multiply out with the divisor, (y-3)
I hope this helps.
We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
