The next number is 17.
-3 + 2 = -1
-1 + 4 = 3,
3 + 6 = 9
9 + 8 = 17

Answer:

$3^{ -x+3}$

Step-by-step explanation:

We need to simplify out the given exponential expression . The given expression to us is ,

$\rm\implies \dfrac{\dfrac{1}{3}}{3^{x-4}}$

We can use the <u>Law of </u><u>Exponents</u> to simplify the given expression . Recall that ,

$\rm\implies \red{\dfrac{a^m}{a^n}= a^{m-n}}$

Note that , we can write ,

$\rm\implies \dfrac{1}{3}= 3^{-1}$

Therefore our expression becomes ,

$\rm\implies \dfrac{ 3^{-1}}{3^{x-4}}$

Simpify using the Law of Exponents ,

$\rm\implies 3^{ -1 - ( x - 4 )}$

Open the brackets in exponent ,

$\rm\implies 3^{ -1 - x +4 }$

Simplify to get final expression ,

$\rm\implies \boxed{\quad \blue{ 3^{-x+3} \quad}}$

Line L1, L2 and L3 are in the same plane, L1 is perpendicular to L2, and L3 is parallel to L1. which of the following statement

exis [7]

Only Statement 2 is surely correct.
because there maybe chances that the line L1 and L3 lies above the line L2 and they can also fulfill the condition of perpendicularity so we can't be sure about statement 3 & statement 1 is clearly incorrect

Need help with this I am not good in Geometry

Answer:

Step-by-step explanation:

Lines p and line r are parallel. This actually means that they will extend continuously without meeting at a point.

Let us assign an alphabet to an angle to make it easy for reference. The diagram is shown in the attached photo

From the photo,

Angle T is equal to 34 degrees. This is because angle T and 34 degrees are corresponding angles.

Angle G = angle T. This is because angle T is vertically opposite to angle G. Therefore

G = 34 degrees

Please help me!! Iv been stuck!

Sloan [31]

Answer:

$7$

Step-by-step explanation:

Because the leftmost triangle is a 45-45-90 isosceles right triangle, $a = b =\frac{7\sqrt2}{\sqrt2} = 7\\$

The rightmost triangle is a 30-60-90 triangle, and the side lengths are in the proportion $1:\sqrt3:2$ from shortest to longest. Therefore, $c = 7\cdot\frac{\sqrt3}{1} = 7\sqrt{3} \implies \boxed{7}$
