Answer:

{(-6,-6), (-2,-2), (7,-6), (-5,0)}

Step-by-step explanation:

Function: Every domain (x-value) has only one range (y-value)

The other choices had an x-value that had more than one y-value, which makes only this one a function.

Hope this helped :)

Y=3x-5 6x+3y=15 what is the value of y in the following system

Darina [25.2K]

y=3x - 5....(i)

6x+3y=15.....(ii)

Then,

Keeping value of y in (ii)equation;

or,6x+3(3x-5)=15

or,6x+9x-15=15

or,15x=15+15

or,x=30/15

:x=2

Now, Keeping value of x in (i) equation;

 y= 3x-5

or, y= 3×2 - 5

or,y= 6-5

: y=1

Answer:

$\Huge\boxed{2x^3+5x^2-7x+20}$

Step-by-step explanation:

$\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd$

$(x+4)(2x^2-3x+5)\\\\=(x)(2x^2)+(x)(-3x)+(x)(5)+(4)(2x^2)+(4)(-3x)+(4)(5)\\\\=2x^3-3x^2+5x+8x^2-12x+20\\\\\text{combine like terms}\\\\=2x^3+(-3x^2+8x^2)+(5x-12x)+20\\\\=2x^3+5x^2-7x+20$
