Answer:
see below
Step-by-step explanation:
take f(x)=5x-6, which is y=5x-6
switch the y for x and x for y and you get
x=5y-6
then add 6 on both sides and you get
x+6=5y
now divide both sides by 5 and you get
y=(x+6)/5
which is the inverse of the original function

Answer:
Step-by-step explanation:
The discriminant comes from the quadratic formula. We use the discriminant to determine, before factoring, what types of solutions we can expect when we do factor. In the quadratic formula, the discriminant is under a square root sign. If the number under a square root sign is negative (meaning the discriminant is negative), we will not have real number solutions because you can't have a negative number under a square root. So a is your choice.
I’d say no because a complementary angle is 2 or more angles with a sum of 90 degrees [tip for differentiating supplementary and complementary angles: complementary (c) comes first in the alphabet (this is 90 degrees) and supplementary (s) comes later (this is 180 degrees. 180 comes later in counting] Anyway, an obtuse angle is more than 90 degrees which already can’t be a sum. (I’m not 100% sure but I hope this helps!)
