Solve using elimination. 10x + y = -19 10x + 3y = -17

Subtract 10x

10x + y = -19

10x + 3y = -17

You would get:

-2y = -2

Two negatives make a positive number! Divide

y = 1

Plug in

10x + (1) = -19

10x = -20

Divide

x = -2

Your solutions are

x = -2

y = 1

we want to add the 2 equations to eliminate a variable

see which constants match

the x's both have 10

multiply the first equation by -1

-10x-y=19

add that to the 2nd equation

-10x-1y=19

10x+3y=-17 +

0x+2y=2

so 2y=2 -> y=1

subsitute to find other number

10x+y=-19

10x+1=-19

10x=-20

divide both sides by 10

x=-2

the solution is (x,y)=(-2,1)

step-by-step explanation:

u have to pay atttion to me

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.
