Step 1: Simplify both sides of the equation.

−3x+8+5x=−4

(−3x+5x)+(8)=−4(Combine Like Terms)

2x+8=−4

2x+8=−4

Step 2: Subtract 8 from both sides.

2x+8−8=−4−8

2x=−12

Step 3: Divide both sides by 2.

2x

2

=

−12

x=−6

valentinak56 [21]

Answer:

The longest bar in her histogram is the Intervals 5-9 with the value of 5

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo

My answer:

  • Intervals 0-4 : there are 2 results
  • Intervals 5-9 : there are 5 results
  • Intervals 10-14 : there are 4 results
  • Intervals 15-19 : there are 5 results

So the longest bar in her histogram is the Intervals 5-9 with the value of 5

Hope it will find you well.

Find a formula for the inverse of the function. f(x) = e^6x − 9
STatiana [176]

Answer:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

Step-by-step explanation:

So we have the function:

f(x)=e^{6x}-9

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

x=e^{6f^{-1}(x)}-9

Add 9 to both sides:

x+9=e^{6f^{-1}(x)}

Take the natural log of both sides:

\ln(x+9)=\ln(e^{6f^{-1}(x)})

The right side cancels:

\ln(x+9)=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

And we're done!
