X = 10
3x + 5y = 20
What is the solution (x, y) of the system of equations?

X=10

Y=-2

Step-by-step explanation: The value of X is given therefore you use it to find the value of Y in the equation:

3(10)+5y=20

5y=20-30

5y=-10

5y/5=-10/5

5 is cancelled out leaving y=-2

I hope this helps. :)

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
