Answer:

No solution

Step-by-step explanation:

Given two equations are 2x+4y= -8 and 4x+8y= 5

These two lines are parallel They don't have a solution because they do not meet .

Multiply the first equation by 2 we get 4x+8y = -16

the other equation is 4x+8y= 5 clearly these two are parallel .

To prove by elimination method we have subtract those two equations we get 21≠0 which is not possible.

Therefore there is no solution to the given set of equation.

What transformation takes the graph of f(x)=2x+3 to the graph of g(x)=2x+4 ?
Zolol [24]

The original function f(x) = 2x+3.

And the transformed function is g(x) = 2x+4.

We can see that if we add 1 into function f(x), we get

f(x) +1 or 2x+3+1 = 2x+4.

<h2>So, 1 is being added in original function f(x)  and we get g function g(x) = 2x+4.</h2>

<em>According to rules of transformations, when we add some number k in the given function, it move k units up and if we subtract k from given function, it move k units down.</em>

<h3>Therefore, correct option is B option.</h3><h3>B. translation 1 unit up.</h3>
