Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationa

Dimas [21]

These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match.

Hope this helps!

F(x)=2x^2 -5 , simplify f(x+h)/h , where h≠0

7nadin3 [17]

Answer:

$\huge\boxed{\dfrac{f(x+h)}{h}=\dfrac{2x^2+4xh+2h^2-5}{h}}$

$\huge\boxed{\dfrac{f(x+h)}{h}=\dfrac{2x^2-5}{h}+4x+2h}$

Step-by-step explanation:

$f(x)=2x^2-5\\\\\dfrac{f(x+h)}{h}=\dfrac{2(x+h)^2-5}{h}=\dfrac{2(x^2+2xh+h^2)-5}{h}\\\\\dfrac{f(x+h)}{h}=\dfrac{2x^2+4xh+2h^2-5}{h}\\\\h\neq0$

How do I solve this using elimination? 80x + 45y = 645 x + y = 12

sergeinik [125]

X + y = 12 / x (-45);
Then, -45x - 45y = -540;
We have 80x + 45y = 645 and
-45x - 45y = -540
________________
35x = 105;
Finally, x = 105÷35;
x = 3;
y = 12 - 3;
y = 9;
