Answer:

22.5 pages

Step-by-step explanation:

First divide the page number by the minutes it takes to read them to find pages per minute-

4.5 / 12 = .375

Then take that number and multiply it by the minutes in an hour-

(.375) (60) = 22.5

22.5 pages in one hour.

21 - 4x = 108

Subtract 21 from both sides

-4x = 87

Divide both sides by -4

x = -21.75

The first term of an arithmetic sequence is equal to four and the common difference is three. find the formula for the value of

hichkok12 [17]

The formula for the value of nth term is $a_{n}$ = 3n + 1

Step-by-step explanation:

The formula of the nth term in the arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

a is the first term of the sequence
d is the common difference between each two consecutive terms

∵ The first term of an arithmetic sequence is equal to four

∴ a = 4

∵ The common difference is equal to three

∴ d = 3

- Substitute these values in the rule of the nth term

∵ $a_{n}=a+(n-1)d$

∴ $a_{n}=4+(n-1)3$

- Simplify it

∴ $a_{n}=4+3n-3$

∴ $a_{n}=1+3n$

The formula for the value of nth term is $a_{n}$ = 3n + 1

K(1,0), L(4,1), M(1,4), N(-2, 3) 90% counterclockwise rotation

docker41 [41]

Answer:

K (0,1)

L (-1,4)

M (-4,1)

N (-3,-2)

Step-by-step explanation:

When you rotate a figure 90 degrees counterclockwise about the origin, the points all change from (x,y) to (-y,x). Therefore the points would go from: (answers on right side)

K (1,0) ---> K (0,1)

L (4,1) ---> L (-1,4)

M (1,4) ---> M (-4,1)

N (-2,3) ---> N (-3,-2)
