PLEASE HELP For what value of the variable will the value of 2x+1 be 20 greater than 8x+5?

wlad13 [49]

It will be a negative.

for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11

-2(2) + 1 = -3

but that's only 8 apart, so it'd be higher.

-4(2) + 1 = -7

-4(8) + 5 = -27

BOOM

Tadaaaa,

You probably thought positive, but sometimes it's negative, you know what I mean?

Use the graphs below to help you answer the question. Which of the following is the best approximation to a solution of the equa

brilliants [131]

Answer:

2 is the correct option.

Step-by-step explanation:

We have the equation $e^x=4x+1$ .

We will plot the graphs of the function $e^x$ and $4x+1$ .

Then, the intersection points of both the graph will be the solution of the equation $e^x=4x+1$ .

From the graphs, we see that,

The intersection points of the graphs are (0,1) and (2.337,10.347).

The solution of the equation is the value of 'x' co-ordinate where they intersect.

So, we get, x = 2 is the correct option.
