Answer:

A function is a relation that for each input, there is only one output.

Here are mappings of functions. The domain is the input or the x-value, and the range is the output, or the y-value.

Each x-value is related to only one y-value.

Athough the inputs equal to -1 and 1 have the same output, this relation is still a function because each input has just one output.

This mapping is not a function. The input for -2 has more than one output.

I hope that helps. I don't know if it is right or wrong, but good luck :)

Amar is making giant holiday cookies for his friends at school. He makes each cookie with 6 oz of cookie dough and decorates the

g100num [7]

Answer:

$13\frac{1}{3}\ cookies$

Step-by-step explanation:

we know that

Amar makes each cookie with 6 oz of cookie dough

we have

5 lb of cookie dough

Convert to ounces

1 lb=16 oz

5 lb=5*16=80 oz

Using proportion

Let

x ------> the number of cookies

$\frac{1}{6}\frac{cookie}{oz}=\frac{x}{80}\frac{cookies}{oz}\\\\x=80/6\\ \\x=13.33\ cookies$

Convert to mixed number

$13.33=13\frac{1}{3}\ cookies$

therefore

He can make $13\frac{1}{3}\ cookies$

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches. If the girth is 63

tester [92]

Answer:

Length of package can be = 22 inches

Step-by-step explanation:

Given:

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches

To find length of package when girth of package is = 63 inches

Solution:

Let length of package be = $l$ inches

Let girth length of package be = $g$ inches

Sum of length and girth of package = $(l+g)$ inches

To qualify for a certain postage rate the sum of length and girth should not exceed 85 inches.

Thus, the inequality representing the situation can be given as:

$l+g\leq 85$

We are given girth of package is = 63 inches

So, inequality to find length would be:

$l+63\leq 85$

Subtracting both sides by 63.

$l+63-63\leq 85-63$

$l\leq 22$ inches

So, length should not exceed 22 inches in order to qualify.

Thus, the maximum length of package to qualify for the postal rate must be = 22 inches

Simplify 12^4 times 30^8 times 125^2 divided by 128^4 times 625^3 timed 27^6

natta225 [31]

Answer:

25/2985984

Step-by-step explanation:

12^4*30^8*125^2/(128^4*625^3*27^6)

(2^2*3)^4*(2*3*5)^8*(5^3)^2/(2^7)^4*(5^4)^3*(3^3)^6)

(2^8*3^4*2^8*3^8*5^8*5^6)/(2^28*5^12*3^18)

2^(8+8-28)*3^(4+8-18)*5^(8+6-12)

2^-12*3^-6*5^2

25/(2^12*3^6)

25/2985984
