If (x)=2x+10,then f^-1(x)

Mathematics
1 answer:
vovangra [49]3 years ago
8 0
If f(x) = 2x + 10, then x = 2(f^-1(x)) + 10
[swap f(x) for x and x for f^-1(x)]

Rearrange:
2(f^-1(x)) = x - 10
f^-1(x) = (x - 10)/2

a scalene triangle has symmetry with respect to a line containing a median of the triangle . true or false
statuscvo [17]
Hi! Let me help you!
Before I answer your question, I should first introduce you to triangles! There ae three triangles: Isosceles triangle, equilateral triangle, and scalene triangle. If I remember it right, isosceles triangles have at least one line of symmetry; an equilater triangle must have three lines of symmetry; a scalene triangle HAS NO line of symmetry.

Now, to answer your question: the answer is FALSE. Scalene triangles have no line of symmetry.

I hope this helped you!

Solve for y. ln(y-1)-ln2=x+ln x
alexandr402 [8]
ln(y - 1) - ln(2) = x + ln(x)
e^{ln(y - 1) - ln(2)} = e^{x + ln(x)}
\frac{e^{ln(y - 1)}}{e^{ln(2)}} = e^{x} * e^{ln(x)}
\frac{y - 1}{2} = e^{x} * x
\frac{1}{2}y - \frac{1}{2} = xe^{x}
2(\frac{1}{2}y - \frac{1}{2}) = 2xe^{x}
y - 1 = 2xe^{x}
y = 2xe^{x} + 1

The table below represents an exponential function what is the common ratio
Greeley [361]

Solution:

Given:

A table representing an exponential function.

The x-values represent the terms, while the y-values represent the numbers.

The common ratio is gotten from the numbers (y-values).

The formula for common ratio is given by;

\begin{gathered} r=\frac{present\text{ term}}{preceed\text{ ing term}} \\  \\ \text{Hence,} \\ r=\frac{108}{36}=\frac{36}{12}=\frac{12}{4}=\frac{4}{1.33\ldots}=\frac{1.33\ldots.}{0.44\ldots} \\ r=3 \end{gathered}

Therefore, the common ratio is 3.
