Answer:

D (0, -2), (1, 0), (3, 3), (4, -5)

Step-by-step explanation:

The first number in a coordinate pair (x, y) is the x, so the first number is how much left or right you go, where the second number is how far up or down you go. if the (x) is negative, you go left, if it's positive you go right, of the (y) is negative you go down, if it's positive you go up.

Answer:

D

Step-by-step explanation:

Answer:

use formula

area = 1/2 *Height *(side 1 + side 2)

Answer:

use the equation of area of parallelogram = height ×base

Answer: I think you should divide them all and if you get the same answer it’s proportional if you don’t get the same answer it’s non-proportional

Step-by-step explanation:

Answer:

It is non-proportional.

Step-by-step explanation:

The table is non-proportional because it expresses a curved line instead of a straight line.

An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5                           ...................(1)

327/6 = 54.5                              ...................(2)

599.5/11 = 54.5                          ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).

Answer:

y= -18

a= -18

Step-by-step explanation:

2y+3 = 3(y+7)

2y+3=3y+21

     -21     -21

2y-18=3y

-2y      -2y

-18=y
