Let <em>f(x)</em> = <em>x</em>³ + <em>x</em> - 5. <em>f(x)</em> is a polynomial so it's continuous everywhere on its domain (all real numbers). Since
<em>f</em> (1) = 1³ + 1 - 5 = -3 < 0
and
<em>f</em> (2) = 2³ + 2 - 5 = 5 > 0
it follows by the intermediate value theorem that there at least one number <em>x</em> = <em>c</em> between 1 and 2 for which <em>f(c)</em> = 0.

A ratio that compares two quantities measured in different units is a conversion factor!
7x+y=11 where y= -5 So, when we substitute y in the equation then,
7x + (-5) = 11 that is 7x - 5 = 11....
So, B. is the right answer.
Answer:
Just like multiplying fractions
Step-by-step explanation:
Rational numbers are like fractions a/b
and they are multiplied straight across
4 6 24 because 4 x 6 = 24
-- x -- = ------
5 7 35 because 5 x 7 = 35
