    2x+3y=5
-3x+2y=-14




3( 2x+3y=5)
  2 (-3x+2y=-14)
--------------------
   13y=-13        ⇒y=-13/13=-1


  2( 2x+3y=5)
-3(-3x+2y=-14)
---------------------
13x  = 52      ⇒x=52/13=4

Answer: x=4; y=-1

To check:
2x+3y=5
2*4+3*(-1)=8-3=5

-3x+2y=-14
-3*4+2*-1=-12-2=-14

For which function does f decrease by 15% every time x increases by 1
LenaWriter [7]

Answer:

f(x) = 0.85^{x}

Step-by-step explanation:

The exponential function that decrease by 15% every time x increases by 1 is given by:

f(x) =  {(1 - 0.15)}^{x}

We simplify the parenthesis to get:

f(x) = 0.85^{x}

Therefore the decrease by 15% every time x increases by 1 is

f(x) =  {0.85}^{x}

The second choice is correct.
