torisob [31]

Answer:

x= 9

y=-12.5

Step-by-step explanation:

3x+2y = 2×2

2x+2y =-7×3

6x+4y =4

- 6×+6y =-21

-2y =25

y=-12,5

2x+2(-12,5)= -7

2x+-25= -7

2x= -7+25

2x/2=18/2

Compute the difference quotient StartFraction f left parenthesis x plus h right parenthesis minus f left parenthesis x right par

kenny6666 [7]

Answer:

$\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3$

Step-by-step explanation:

$f(x)=-4x^2-3x-4$

$f(x+h)=-4(x+h)^2-3(x+h)-4$

$f(x+h)=-4(x^2+2xh+h^2)-3(x+h)−4$

$f(x+h)=-4x^2-8xh-4h^2-3x-3h-4$

$f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4-(-4x2-3x-4)$

$f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4+4x2+3x+4$

$f(x+h) - f(x)=-8xh-4h^2-3h$

$f(x+h) - f(x)=h(-8x-4h-3)$

$\dfrac{f(x+h) - f(x)}{h}=\dfrac{h(-8x-4h-3)}{h}$

$\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3$
