Answer:
Ur question?
Step-by-step explanation:
The correct answer is F(-2)=-23
You are told that y=-5, so just use that value for y in the second equation...
5x+4(-5)=-20
5x-20=-20
5x=0
x=0 so the solution, when the lines intersect, is the point (0,-5)
If quantity t varies inversely with a quantity r ,
Then mathematically t α 1/r,
Introducing a constant, t = k/r .
When t = 6 then r = 5,
therefore, 6 = k/5
k = 6×5
k = 30 (Constant of variation)
Which means the equation connecting t and r will be t = 30/r
To find the value of t when r = 15, we use the equation of this variation
such that, t = 30/15
t = 2
