HELP!! 70 points will be given!<br> Picture included
kkurt [141]

Answer: a) -13/16

Step-by-step explanation: Start by setting equations equal and rearrange X^3 - x^2 + 1 = 0. Visual inspection of graph shows x between -1 and -1/2. Start with x = 3/4 plug in and calculate: just a little too small. Try going halfway towards -1: x =-7/8 Plug in and the answer is very far from 0. Go halfway back towards -3/4: -13/16 and the equality is very close.

FOR BRAINLIEST<br> Express 0.64 as a fraction in lowest terms.<br> 5/32<br> 64/10<br> 16/25<br> 4/5
Nadusha1986 [10]

Answer:In its decimal form, it says  ' 64 / 100 '.

In order to change it to its lowest terms, we look to see whether the

numerator and denominator have a common factor greater than ' 1 '.

If they do, then we can divide numerator and denominator by their

common factor, and have the same fraction in lower terms.

The common factors of  64  and  100  are  1,  2, and  4 .

We could divide top and bottom by 2, but that wouldn't finish the job.

It's always best to divide them by their greatest common factor, and

once you do that, you're done.

Dividing the numerator and denominator both by  4,

we get the fraction in its lowest terms:

        0.64  =  64/100  =  16/25
