7.96 / 6 = 1.33 <== unit rate
Step-by-step explanation:
I think its D: table sugar
We can write this as:-
P(x) = + x^3 - 5x^2 - 25x + 125
There are 2 changes of real sign so by Descartes Rule of signs there are either 2 positive real roots or 0 positive roots.
P(-x) = - x^3 - 5x^2 + 25x + 125
There is just one change of sign so there is exactly 1 real negative root.
125 is a multiple of 5 so By rational root theorem 5 could be a positive root.
P(5) = 125 - 125 - 125 + 125 = 0 so one zero is 5
if we divide the polynomial by (x - 5) we get the quadratic
x^2 - 25
(x + 5)(x - 5) = 0
x = 5,-5
so the roots are 5 (multiplicity 2) and -5.
2 real positive zeroes and one real negative zero
Answer:
the value of x is 3

Hope this helps!!!! :)
$128
We have the rate “$176 for 11 hours of work”
Find the unit rate of dollars per hour by:
Divide 176 ÷ 11 = 16
UNIT RATE: $16 per hour
Now find how much dollars for 8 hours by:
Multiply 16 • 8 = 128
FINAL ANSWER:Mary would earn $128 for 8 hours of work

Have a nice day!
