3x+2y=2 Y=x-9 A) (4,-5) B) (4,13) C) (-5,4) D) (20,11)

BlackZzzverrR [31]

Y = X - 9
so 3X +2Y = 2
will be 3X +2×(X-9) = 2
3X + 2X -18 = 2
5X = 2 + 18
5X = 20
X = 4
Y = X - 9
Y = 4-9
Y = -5
the answer will be A) (4,-5)

If s(x) = 2x2 + 3x - 4, and t(x) = x + 4 then s(x) · t(x) =

Paladinen [302]

Answer:

$\large\boxed{s(x)\cdot t(x)=2x^3+11x^2+8x-16}$

Step-by-step explanation:

$s(x)=2x^2+3x-4,\ t(x)=x+4\\\\s(x)\cdot t(x)\\\\\text{use the distributive property:}\ a(b+c)=ab+ac\\\\s(x)\cdot t(x)=(2x^2+3x-4)(x+4)\\\\=(2x^2+3x-4)(x)+(2x^2+3x-4)(4)\\\\=(2x^2)(x)+(3x)(x)+(-4)(x)+(2x^2)(4)+(3x)(4)+(-4)(4)\\\\=2x^3+3x^2-4x+8x^2+12x-16\\\\\text{combine like terms}\\\\=2x^3+(3x^2+8x^2)+(-4x+12x)-16\\\\=2x^3+11x^2+8x-16$
