Answer:

√15/3

Step-by-step explanation:

x² - y² =√5

(x +y)*(x -y) = √5

(x +y) * √3 = √5

x+y  = √5 / √3

x +y = √5*√3 / √3*√3

x +y = √15/3

Scrat [10]
The answer is 194 because you multiply 59 and 500 and then 38 and 500 you then get 29,500 plus 19,000 divided by 250 you add the two together and get 48,500 divided by 250 and end up with 194

(03.01) Is the following relation a function? y equals the sine of 3 x
nikdorinn [45]
A relation is a function if it passes the vertical line test.  That graph in a coordinate plane is just a sin wave that is spread out.  If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time.  That makes it a function.  It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!

PLSSS HELP IF YOU TURLY KNOW THISS
xxMikexx [17]

Answer:

2 1/2

Step-by-step explanation:

Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.

4 3/4

4 * 4 + 3 = 19

19/4

2 1/4

2 * 4 + 1 = 9

9/4

Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.

19/4 - 9/4 = 10/4

Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:

4 * 2 = 8

10 - 8 = 2

2 1/2
