F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2
f(f^-1(x)) = x so answer is -2
10^6/10^-3 = 10^6-(-3) = 10^6+3 =
10^9
Answer has decimal numbers or fraction any you like to choose
Hello!
To put -3x-7y-14=0 into standard form, or ax+by=c where the a value cannot be negative, and there are no fractions or decimals, or any common factors, first add -14 to both sides to get -3x-7y=14. Then, since your a value is negative, multiply the entire equation by -1 which will result in your answer:
3x+7y=-14
Hope this helps!
I am assuming this is a trapezoid.
The area of a trapezoid is : A=(B1+B2)H/2
Plug in the numbers to get:
18=(6+B2)*2/2
18=6+B2
18-6=6-6+B2
B2=12
