thus, the best car is car B,because it can tavel 29 miles with only one gallon,andcar A can only travel 28 miles with one gallon.
Answer:
-1
Step-by-step explanation:
15x-8x-2=-9
Or, 7x=-9+2
Or, 7x=-7
Or, x=-7/7
Or, x =-1
3 divided by 10 is 0.3
2 divided by 5 is 0.4.
They are not equivalent.
The function is :
y = √(x-12), x≥12
To find the inverse function, we interchange x and y, and then make y the subject again.
So interchanging x and y we have:
x = √(y-12)
Squaring both sides gives;
x² = y-12
Now making y the subject we have,
y = x² +12
x≥0.
Therefore the inverse function is;
y = x² +12, x≥0.
Hence the correct answer is C.
