Write a recursive rule for the sequence 4,10,16,22
Phantasy [73]

Answer:

a_{n+1} = a_{n} + 6

Step-by-step explanation:

The terms have a common difference d between consecutive terms, that is

10 - 4 = 16 - 10 = 22 - 16 = 6

To obtain the next term add 6 to the previous term ( recursive rule ), thus

a_{n+1} = a_{n} + 6 with a₁ = 4

NC Check-Ins 2 Math Grade 7 - NC Check-In 2- 2020-21 - Form 5657
sveticcg [70]

Answer:

33

Step-by-step explanation:

Given that :

Card numbered from: 500 - 799

The required number of values must meet both conditions 1 and 2

Condition 1 : first of the 3 digits is odd :

500 - 599 = 100

700 - 799 = 100

(100 + 100) = 200 cards

Condition 2: three digits is divisible by 6

{500 - 599} and {700 - 799}

The numbers divisible by 6 are 33

Tell wether the angles are adjacent or vertical. Then find the value of x.
Gre4nikov [31]

Answer:

The angles are vertical

Step-by-step explanation:

x+42+2x+1=180

put the like terms together i.e 2x+x+42+1=180

you get: 3x+43=180

Take 43 to th other side of 180 i.e 3x=180-43 i.e (180-43=137)

You get 3x=137

Divide both sides by 3

you get x=45.666666666667(Round off to get 45.67)

Substitute the value of x to the angles

x+42(45.67+42=87.67)

2x+1(2(45.67)+1=92.34

Add 87.67+92.34=180

THis shows that the angles are vertical
