Answer:

x = -10

y = 13

Step-by-step explanation:

-3x + 2y = 56

-5x - 2y = 24

__________ +

-8x____ = 80

x______= 80/-8

______x = -10

-3x + 2y = 56

-3(-10) + 2y = 56

30 + 2y = 56

2y = 56 - 30

2y = 26

y = 26/2

y = 13

F(x)=2x^2+1 using the derivate definition

morpeh [17]

$\bf \stackrel{\textit{de} \textit{finition of a derivative as a limit}}{\lim\limits_{h\to 0}~\cfrac{f(x+h)-f(x)}{h}}\\\\
-------------------------------\\\\
f(x)=2x^2+1\implies \lim\limits_{h\to 0}~\cfrac{[2(x+h)^2+1]~~-~~[2x^2+1]}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{[2(x^2+2xh+h^2)+1]~~-~~[2x^2+1]}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{[2x^2+4xh+2h^2+1]~~-~~[2x^2+1]}{h}$

$\bf \lim\limits_{h\to 0}~\cfrac{\underline{2x^2}+4xh+2h^2\underline{+1}~~~~\underline{-2x^2-1}}{h}\implies \lim\limits_{h\to 0}~\cfrac{4xh+2h^2}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{2\underline{h}(2x+h)}{\underline{h}}\implies \lim\limits_{h\to 0}~2(2x+h)\implies \lim\limits_{h\to 0}~2(2x+0)\implies 4x$
