Answer:

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

A recursive rule for a geometric sequence is a1=2; an= 4/9 an-1

Oxana [17]

A recursive rule for a geometric sequence:

$a_1\\\\a_n=r\cdot a_{n-1}$

---------------------------------------------------

$a_1=2;\ a_n=\dfrac{4}{9}a_{n-1}\to r=\dfrac{4}{9}$

---------------------------------------------------

The exciplit rule:

$a_n=a_1r^{n-1}$

Substitute:

$a_n=2\left(\dfrac{4}{9}\right)^{n-1}=2\cdot\left(\dfrac{4}{9}\right)^n\cdot\left(\dfrac{4}{9}\right)^{-1}=2\cdot\left(\dfrac{4}{9}\right)^n\cdot\dfrac{9}{4}\\\\\boxed{a_n=\dfrac{9}{2}\cdot\left(\dfrac{4}{9}\right)^n}$

Need help with school

Answer: 139°

Reasoning:

Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.

14x-1=9x+14

To isolate the x to one side, subtract the 9x from the 14x.

5x-1=14

Now to get the constants on one side, add the 1 to the 14.

5x=15

Now divide both sides by 5 to isolate the x.

5x/5=15/5

x=3

Now that we know that, we can figure out angle 3.

9(3)+14

27+14= 41

Angle 3 = 41°

Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.

180°- 41°= 139°

<h3>Double checking your answer:</h3>

41°+139°=180°

1. write it on a piece of paper

stiv31 [10]

$\\ \sf\longmapsto 1\dfrac{1}{2}+2\dfrac{3}{4}$

$\\ \sf\longmapsto \dfrac{3}{2}+\dfrac{11}{4}$

$\\ \sf\longmapsto \dfrac{6+11}{4}$

$\\ \sf\longmapsto \dfrac{17}{4}$

2:-

$\\ \sf\longmapsto 4\dfrac{3}{7}+6\dfrac{1}{5}$

$\\ \sf\longmapsto \dfrac{31}{7}+\dfrac{31}{5}$

$\\ \sf\longmapsto \dfrac{155+225}{35}$

$\\ \sf\longmapsto \dfrac{380}{35}$

$\\ \sf\longmapsto 12$

3:-

$\\ \sf\longmapsto 4\dfrac{2}{5}+5\dfrac{2}{6}$

$\\ \sf\longmapsto \dfrac{22}{5}+\dfrac{32}{6}$

$\\ \sf\longmapsto \dfrac{132+160}{30}$

$\\ \sf\longmapsto \dfrac{292}{30}$

4:-

$\\ \sf\longmapsto 3\dfrac{7}{7}+3\dfrac{1}{3}$

$\\ \sf\longmapsto \dfrac{28}{7}+\dfrac{10}{3}$

$\\ \sf\longmapsto 4+\dfrac{10}{3}$

$\\ \sf\longmapsto \dfrac{12+10}{3}$

$\\ \sf\longmapsto \dfrac{22}{3}$
