This means what what angle plus 95° gives you an 180° angle. So an 85° angle measure is supplementary to 95

What is 3 1/2 + 2 1/3

To start off, you should make each fraction have a common denominator.

2*3 = 6
3*2 = 6

The lowest common denominator is six.

so 3 3/6 + 2 2/6 = 5 5/6

Hopefully that helps!

Answer:

the one real zero is in the interval (-1, 0)

Step-by-step explanation:

Descartes' rule of signs tells you there are 0 or 2 positive real zeros. Changing the signs of the odd-degree terms and applying that rule again tells you there is one negative real zero. At the same time, those coefficients (-3, -5, -5, +7) have a negative sum, so you know ...

f(-1) = -6

f(0) = +7

so there is a zero in the interval (-1, 0).

You can try a few values between x=0 and x=10 to see what the function does in that part of the graph. You find ...

f(1) = 10

f(2) = 21

f(3) = 58

So, it is safe to conclude that there are no real zeros for x > 0.

The only real zero of f(x) is in the interval (-1, 0).
