1/3y + 1/2 = 2/3.....multiply everything by common denominator of 6
2y + 3 = 4
2y = 4 - 3
2y = 1
y = 1/2

OR

1/3y + 1/2 = 2/3
1/3y = 2/3 - 1/2
1/3y = 4/6 - 3/6
1/3y = 1/6
y = 1/6 * 3
y = 3/6
y = 1/2

Does the table represent a function if the input is 1,2,3,4 and the output is 3,6,11,18?
skelet666 [1.2K]
Yes..it does. To be a function, all the inputs (x's) have to be different numbers...there can be no repeating x's...there can be repeating outputs (y's)...just not the x's

1. Match the polynomial identity to the correct answer.
Katen [24]

Answer:

a: (a-b)(a+b);b: (a-b)(a^{2}+ab+b^{2});  c: (a^{2} +2ab+b^{2}); d: (a+b)(a^{2}- ab+b^{2})

Step-by-step explanation:

Given the expressions all that is required is to expand them (using the distributive property) to see which answers they match up to:

For a: (a-b)(a+b)=a^{2} +ab-ab-b^{2} =a^{2}-b^2

For b: (a-b)(a^2+ab+b^2)=a^3+a^2b+ab^2-a^2b-ab^2-b^3=a^3-b^3

For c calculate the square of a sum: (a+b)^2=a^2+ab+ab+b^2

(add like terms) c: a^2+2ab+b^2

For d: (a+b)(a^2-ab+b^2)=a^3-a^2b+ab^2+a^2b-ab^2+b^3=a^3+b^3

a box contains 1 3/4 pounds of pancake mix. Jada used 7/8 pound for a recipe. What fraction of the pancake mix in the box did sh
ololo11 [35]

Answer:

Jada used 1/2 of the pancake mix in the box

Step-by-step explanation:

we know that

1\frac{3}{4}\ pounds -----> represent the 100% of the box

so

by proportion

Find what fraction represent \frac{7}{8}\ pounds

First convert mixed number to an improper fraction

1\frac{3}{4}\ pounds=\frac{1*3+4}{4}=\frac{7}{4}\ pounds

\frac{100}{(7/4)}=\frac{x}{(7/8)}\\ \\x= 100*(7/8)/(7/4)\\ \\x=50\%

Convert the percentage into fraction

50\%=50/100=1/2
