Let's start with the x coordinates.

-8 is on the left, and -4 to the right, so that will help organize this.

the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.

rise/run so 1/4 is the slope.

y=(1/4)x - 7

The domain for the graph (in interval notation) is
Ksenya-84 [330]

Answer:

Domain: [-3, 1]

Step-by-step explanation:

Doman is the set of x-values that can be inputted into function f(x).

We see that our x-values span from -3 to 1. Since both have no holes, they are included in our domain:

[-3, 1] or -3 ≤ x ≤ 1

Points O, A, B lie on the same line. OA = 12 cm, OB = 9 cm. Find the distance between the midpoints of segments OA and OB if: Po
12345 [234]
Short Answer: 1.5
Givens
OA = 12
OB = 9
O does not lie on AB

Argument
The order that these lines must be in is OBA. O is on your left, B is in the middle and A is on your right. 

Mark your distances as follows.
OB = 9
BA = 3

Mark the midpoint of OA = M1
Mark the midpoint of OB = M2

M1 = 12 / 2 = 6 so M1 is 6 units from O
M2 = 9/2 = 4.5

The distance between the two midpoints is 6 - 4.5 = 1.5
Answer M1 - M2  = 1.5 <<<<

Nice problem: Thanks for posting.

the coordinates of the vertices of a polygon are (2,4) (6,4) (6,0) and (2,0). The polygon is dilated with a scale factor of 3/2
svlad2 [7]
Take the first point (2, 4)  a scale factor of 3/2 will move the x coordinate 2 to 2*3/2  = 3 and the y coordinate 4 will  be moved to 4*3/2 = 6.
So the image of ( 2, 4) will be ( 3, 6)  TH other verices will move in the same fashion.

The sum of two consecutive integers is 23. what are the integers?
Zepler [3.9K]

Let the consecutive integers be x and x+1.

Then,

x + (x + 1) = 23

=> x + x + 1 = 23

=> 2x + 1 = 23

=> 2x = 23 - 1

=> 2x = 22

=> x = 22/2

=> x = 11

So, the integers are:

x = 11

and x + 1 = 11 + 1 = 12

So, the consecutive integers are 11 and 12.
