19. v/2 = 2 1/30

Turn mixed number(s) to improper fraction(s).
v/2 = 61/30

Multiply both sides by 10.
v/2 × 10 = 61/30 × 10

Simplify.
5v = 61/3

Divide both sides by 5.
5v ÷ 5 = 61/3 ÷ 5

Simplify.
v = 61/15

61/15 or if you want it as a mixed fraction, it would be 4 1/15.

The relation ia a quadratic relation because of the highest Power of x to be 2

Step-by-step explanation:

For

Y=- x+4. Y= 1

Y=x-2. 1= x-2

2y =2. 1+2= x

Y= 1. 3= x

For

Y= x+3. 1= x

Y= 3x+1. Y= 3+1

0= 2x-2. Y= 4

2= 2x

1= x

Y= x²+3x-18

For -5

First difference

25-15= 10

Second difference

10-18= -8

For -4

First difference

16-12= 4

Second difference

4-18= -14

For -3

First difference

9-9= 0

Second difference

0-18 = -18

For -2

Second difference

-2-18= -20

For -1

First difference

1-3 = -2

Second difference

-2-18 = -20

For 0

First difference

0+0 = 0

Second difference

0 -18= -18
