Jimmy will receive -18 marks in the mathematics competition.
3*10=30
-8*6=-48
30+-48=-18
Step-by-step explanation:
The equation of the line is y = 3x - 6 (D).
Yes, because everyone has an equal chance of participating.
First, you would need to calculate how many miles George ran.
1.1 mi + 2.1 mi = 3.2 mi
Now, 1 mile = 1,609.34 meters, so you would multiply the number of meters per mile by the number of miles.
3.2 × 1,609.34 = 5,149.9 meters
George ran 5,149.9 meters in all.
I hope this helps!
the assumption here is that the function f(x), has an inverse function of f⁻¹(x), so let's assume that is indeed the case, f⁻¹(x) is the inverse function of f(x).
for functions and their inverse, if they're indeed inverse of each other, then
f⁻¹( f(x) ) = x
f( f⁻¹(x) ) = x.
