Can anyone me with those 2 questions?

-4x+15y=27 for the first one

-15c+14f=30 for the second one

Step-by-step explanation:

All you have to do is distribute it out and combine like terms

1st: -4x + 15y -21

2nd: -15e + 14f + 30

Step-by-step explanation:

So you would first distrubute the number outside of the parenthesis. So for the first one thats a -3 and for the second one it's a -7. Multiply those by the terms inside and then combine your like terms. That will give you your answers. Hope this helps :)

the answer is b.)

< 1=< 2

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.
