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.

How can you tell if two equations for parallel lines or perpendicular lines. please explain?
kicyunya [14]
To find out if they are parallel we need to see if the gradient is the same, to do this we need to get y in terms of x:
assuming the first equation is x+y+7=0
y=-x-7
and
y=x-3
The gradient is the coefficient of x (the number infront of x)
For equation 1 the gradient is -1, and for number 2 it is 1, therefore they are not parallel.
However to check if they are perpendicular we need to see if their gradients multiply to equal -1.
-1*1=-1 therefore they are perpendicular
