Answer:
k - 2e + 9 = 0
k - e - 4 = 0
Step-by-step explanation:
Given that Elena is currently e years old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.
So, k - 9 = 2(e - 9)
⇒ k - 2e + 9 = 0 .............. (1)
And, in four years, Elena will be as old as Katie is now.
So, k = e + 4
⇒ k - e - 4 = 0 ............... (2)
Therefore, the equations (1) and (2) matches the conditions. (Answer)
Answer:
The exact amount of British pounds would be 81.769
Step-by-step explanation:
slope = 2 and y-intercept = 0
the equation of a line in ' slope- intercept form ' is
y = mx + c ( mis the slope and c the y-intercept )
given 2x - y = 0 ( add y to both sides )
2x = y or y = 2x + 0 ← in slope-intercept form
with slope m = 2 and y-intercept c = 0
