Step-by-step explanation:

hello : let An = 2n - 6

1) the first three terms are :

the first term is : when n= 1 A1 =2(1)-6 = 2-6 = -4

the second term is : when n= 2 A2 = 2(2)-6 = 4-6 = -2

the third term is : when n= 3 A3 = 2(3)-6 = 6-6=0

2) the tenth term is : when n= 10 A10=2(10)-6 =20-6=14

Answer:

Step-by-step explanation:

2n - 6

a) n = 1 ; 2n - 6 = 2*1 - 6 = 2 - 6 = -4

n = 2 ; 2n - 6 = 2*2 - 6 = 4 - 6 = -2

n = 3 ; 2n - 6 = 2*3 - 6 = 6 - 6 = 0

b) n=10; 2n - 6 = 2*10 - 6 = 20 - 6 = 14

Which pair of figures appears to be congruent

inn [45]

Answer:

when they have equal sides and the exact shape and the same angle measures. they have tobe the same size.

Step-by-step explanation:

For example, when you have a square with sides 3 cm, then you compare it with the exact copy of the square. These squares are congruent. Two figures are congruent if and only if they have the exact same shape and the exact same size. If the corresponding sides of two figures with the same shape have the same length, then the two figures are congruent.

Barney's Book Store currently has 2000 books in stock. There are 3 times as many non-fiction books as fiction books. Determine t

xxMikexx [17]

Answer:

There are 1500 non fiction books and 500 fiction books currently in the store.

Step-by-step explanation:

Given:

Total Number of books = 2000

Let the number of fiction books be 'x'.

Now given:

There are 3 times as many non-fiction books as fiction books.

Number of non fiction books = $3x$

We need to find the number of non-fiction and fiction books.

Solution:

Now we know that;

Total Number of books is equal to sum of the number of non-fiction and fiction books.

framing in equation form we get;

$x+3x=2000\\\\4x=2000$

Dividing both side by 4 we get;

$\frac{4x}{4}=\frac{2000}{4}\\\\x= 500\ books$

Number of fiction books = 500

Number of non fiction books = $3x=3\times 500 =1500$

Hence There are 1500 non fiction books and 500 fiction books currently in the store.

Write the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1). Include your work in y

lys-0071 [83]

First find the slope,
m=(y2-y1)/(x2-x1)=(1-(-9))/(7-6)=10
Next, use the point slope form to find the equation:
L : y-y1=m(x-x1) => y-1=10(x-7)
[in point slope form, point is (7,1), slope=m=10 ]
