Solve for y in terms of x. x=(y+2)/(y+3)

1 answer:

7 0

Multiply both sides by y+3 to get xy+3x=y+2. Subtract 2 from both sides as well as xy, getting 3x-2=y-xy. After that, divide y from both sides to get (3x-2)/y=1-x. After that, divide both sides by (3x-2) to get 1/y=(1-x)/(3x-2). After that, multiply both sides by y to get 1=y(1-x)/(3x-2), and then multiply both sides by
(3x-2)/(1-x) to get (3x-2)/(1-x)=y

Step-by-step explanation:

Given

number of students at WMS = 136+188 = 324

number of students at PMS = 316+208 = 524

Ratio of students

WMS : PMS = 324 : 524 = 81 : 131

State which of the following ordered pairs is a function. Set A: (-1, 0), (-2, 1), (4, 3), (3, 4) Set B: (1, 4), (2, 3), (3, 2),

Mice21 [21]

Answer:

Both set A and B.

Step-by-step explanation:

Set A: (-1, 0), (-2, 1), (4, 3), (3, 4)

Set B: (1, 4), (2, 3), (3, 2), (4, 1)

Set C: (2, 1), (3, 2), (2, 3), (1, 4)

In order for (x,y) to be a function, only one x get the value of y, but many x'es can get the value y.

Looking at the set A and B, and the definition above, we can say that they are functions.

What about set C? It is not a function, as x = 2 is equal 1 or 3, which does not meet the condition from the definition.
