A negative rational number that is not a integer? Examples

2 answers:

8 0

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

1-25. Given f(x) =- 2/3x +3 and g(x) = 2x2 - 5, complete parts (a) through (f).

Korolek [52]

Answer:

When f or g are equivalent to a number you are solving for x. For example b, d, e, f. In the equation g(x) =2x2-5 I assumed 2 was a typo. So, if it's incorrect, please use same steps and just adjust the solution.

Step-by-step explanation:

$f(x)=-\frac{2}{3x}+3$

a) $f(3)=-\frac{2}{2(3)} +3$

$=-\frac{1}{3}+3$ $=\frac{-1+6}{3}$ $=\frac{5}{3}$

b) $f(x)=-5$

$-5=-\frac{2}{3x}+3$

$-8=-\frac{2}{3x}$

$-24x=-2$

$x=\frac{1}{12}$

$g(x)=2x-5$

c) $g(-3)=2(-3)-5$

$=-6-5$

$=-11$

d) $g(x)=-7$

$-7=2x-5$

$-2=2x$

$x=-1$

e) $g(x)=8$

$8=2x-5$

$12=2x$

$x=6$

f) $g(x)=9$

$9=2x-5$

$11=2x$

$x=\frac{11}{2}$

Answer:

Approximately 920.324 p/m

Step-by-step explanation:

so to figure this out, we need to simply divide 6,688 people by 7.267 square miles. 6,688/7.267=920.324.... So we have approximately 920.324 people per square mile
