Answer:

2x  -8  =6

     

add 8 to -8 and 6.

the 8s cancel each other out and 6 +8 =14.

next you are going to divide 2x diveded by 2 and 14 by 2. the twos cancel out so its just x and then 14/2 is 7.

the answer is 7. hope this helps dude.

Write a recursive formula for each explicit formula
Crazy boy [7]

Answer:

38. a_1=107,\ a_n=a_{n-1}-1

40. a_1=87,\ a_n=a_{n-1}+52

Step-by-step explanation:

38. <u>Given explicit formula:</u>

a_n=108-n

When n=1, then a_1=108-1=107

When n=2, then a_2=108-2=106

When n=3, then a_3=108-3=105

When n=4, then a_4=108-4=104

and so on

You can see that each next number is 1 less than previous number, so the recursive formula is

a_n=a_{n-1}-1

40. <u>Given explicit formula:</u>

a_n=35+52n

When n=1, then a_1=35+52\cdot 1=87

When n=2, then a_2=35+52\cdot 2=139

When n=3, then a_3=35+52\cdot 3=191

When n=4, then a_4=35+52\cdot 4=243

and so on

You can see that each next number is 52 more than previous number, so the recursive formula is

a_n=a_{n-1}+52

8. Write the composition of translations T(7,8) •T(-3,-4)<br> as one translation.
11111nata11111 [884]

Answer:

T (4, 8)

Step-by-step explanation:

T(7,8) •T(-3,-4) = T ( -3+7, -4+8) = T( 4, 4 )

Instead of moving

(3 units to the left, and 4 units down) then ( 7units to the right and 8 units up) we could get to the same place by moving

( 4 units to the right and 4 units up)
