Which of the following is not a function?

Cerrena [4.2K]

The guy who links files is pretty annoying amiright...

Divide 18/35 by 3/5 to get your answer. You can also multiply 3/5 by 35/18.

5 goes into 35 7 times, so cross out the 5 and 35 and put 1 and 7. 3 goes into 18 6 times, so cross out the 3 and 18 and put 1 and 6.

Now you have 1/1 times 7/6. Your answer is 7/6.

emmasim [6.3K]

Answer:

h<-8/3

Step-by-step explanation:

collect like terms

-10h+7h>9-1

3h>8

divide both sides of the inequality by -3 and flip the inequality sign

h<-8/3

Which algebraic expression is a polynomial with a degree of 3?

Irina18 [472]

Option a: $4x^{3} -\frac{2}{x}$

Option b: $2y^{3} +5y^{2} -5y$

Option c: $3y^{3} -\sqrt{4y}$

Explanation:

The highest degree of a polynomial is the largest exponent of that variable.

Now, we shall determine the polynomial with degree 3.

Option a: $4x^{3} -\frac{2}{x}$

From the expression $4x^{3} -\frac{2}{x}$ , the highest degree of the polynomial is 3.

Hence, $4x^{3} -\frac{2}{x}$ is a polynomial with a degree of 3.

Hence, Option a is the correct answer.

Option b: $2y^{3} +5y^{2} -5y$

From the expression $2y^{3} +5y^{2} -5y$ , the highest degree of the polynomial is 3.

Hence, $2y^{3} +5y^{2} -5y$ is a polynomial with a degree of 3.

Hence, Option b is the correct answer.

Option c: $3y^{3} -\sqrt{4y}$

From the expression $3y^{3} -\sqrt{4y}$ , the highest degree of the polynomial is 3.

Hence, $3y^{3} -\sqrt{4y}$ is a polynomial with a degree of 3.

Hence, Option c is the correct answer.

Option d: $-xy\sqrt{6}$

From the expression $-xy\sqrt{6}$ , the highest degree of the polynomial is 1.

Hence, $-xy\sqrt{6}$ is a polynomial with degree 1.

Hence, Option d is not the correct answer.

There are 122,100 public school teachers in Ohio and Ohio has a population of 11.6 million people. Illinois has a population of 12.9 million people. If the number of public school teachers per capita in Illinois was proportional to that of Ohio, how many public school teachers would we expect Illinois to have?

This problem uses proportionality or the relationship between two values. Typically, proportions are expressed as fractions. So, we can set this up as

$\frac{Teachers}{Population}$ and we can use this to express both of our values. So, for Ohio, we have $\frac{122,100}{11,600,000}$ and for Illinois we have $\frac{x}{12,900,900}$ . Now, because they are proportional, we can set them equal to each other and we get $\frac{122,100}{11,600,00} = \frac{x}{12,900,000}$ . Now we can cross multiply to get $11,600,000x=1446090000000$ . To get the $x$ alone on one side, we divide by $11,600,000$ and we get 124,662.931034, which is about equal to 124,663.

Therefore, we expect Illinois to have 124,663 public school teachers
