Hello, please consider the following.

{2}^{x + 2 } = 9 \times( {2}^{x} ) - 2\\\\2^x \cdot 2^2=9\cdot 2^x-2\\\\(9-4)2^x = 2\\\\2^x=\dfrac{2}{5}\\\\\text{We take the ln.}\\\\xln(2)=ln(2)-ln(5)\\\\x=\dfrac{ln(2)-ln(5)}{ln(2)}=-1.32193...

Let me know if you need further explanation.

Thank you

Solve the inequality. Graph the solution set. 2r−9≤−6
Annette [7]

Hey there! :)

2r - 9 ≤ -6

To solve for r, we must move all variables to one side.

So, let's start out by adding 9 to both sides.

2r - 9 + 9 ≤ -6 + 9

Simplify.

2r ≤ 3

Divide both sides by 2.

2r ÷ r ≤ 3 ÷ 2

Simplify.

r ≤ 3/2

Simplify so that we don't have improper fractions.

r ≤ 1 1/2

Therefore, r is lesser than or equal to 1 1/2.

Using the process of elimination, we can see that the only answer choice that has r ≤ 1 1/2 in it is the THIRD answer choice.

~Hope I helped!~
