Answer:

x = 11

Step-by-step explanation:

If A were parallel to B, alternate exterior angles would be congruent.

Equation:

5x + 9 = 6x - 2

9 + 2 = 6x - 5x

11 = x

Hope this helps!

Let me know if you clarification :)

Answer:

x = 11

Step-by-step explanation:

If both lines were parallel, then the angles with labels would be alternate angles between parallel lines, which will make them equal in measure.

so the measure of one (5x+9) would equal the measure of the other one (6x-2) which in math terms becomes:

5 x + 9 = 6 x - 2

subtract 5x from both sides:

9 = x - 2

add 2 on both sides

x = 11

What is the explicit rule for the geometric sequence?<br> 600, 300, 150, 75, ...

pochemuha

Answer:

Step-by-step explanation:

Hello, this is a geometric sequence so we are looking for a multiplicative factor.

$a_0=600\\\\a_1=a_0 \cdot \boxed{\dfrac{1}{2}} = 300 = 600 \cdot \boxed{\dfrac{1}{2}}\\\\a_2=a_1 \cdot \boxed{\dfrac{1}{2}} = 150= 300 \cdot \boxed{\dfrac{1}{2}}\\\\a_3=a_2 \cdot \boxed{\dfrac{1}{2}} = 75 = 150 \cdot \boxed{\dfrac{1}{2}}$

So, the explicit formula is for n

$\boxed{a_n=a_0\cdot \left(\dfrac{1}{2}\right)^n=600\cdot \left(\dfrac{1}{2}\right)^n}}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
