Which is the best approximation to a solution of the equation e^x = 2x + 3?

TiliK225 [7]

The correct question is
Which is the best approximation to a solution of the equation
e^(2x) = 2e^{x) + 3?

we have that

e^(2x) = 2e^{x) + 3-----------> e^(2x)- 2e^{x) - 3=0
the term
e^(2x)- 2e^{x)----------> (e^x)²-2e^(x)*(1)+1²-1²------> (e^x-1)²-1

then
e^(2x)- 2e^{x) - 3=0--------> (e^x-1)²-1-3=0------> (e^x-1)²=4
(e^x-1)=2--------> e^x=3
x*ln(e)=ln(3)---------> x=ln(3)
ln(3)=1.10
hence
x=1.10

the answer is x=1.10

What is the slope of the line that passes through the points (7,26) and (12, -39)?

Elena-2011 [213]

The slope (m) = -13.

We can use the slope formula:

m = (y2 - y1) / (x2 - x1)

Let (x1, y1) = (7, 26)
(x2, y2) = (12, -39)

Plug in the values into the formula:

m = (y2 - y1) / (x2 - x1)
m = (-39 - 26) / (12 - 7)

m = -65/5

m = -13
