The sum of the numerator and denominator of a fraction is 3 less than twice the denaominator if the numerator and denominator are decreased by 1 the numerator becomes half the denominator

answer:

step-by-step explanation:

the numerator be 'x' and denominator be '  y'

then,

the sum of the numerator and denominator of a fraction is 3 less than the twice is x+y=2y-3 : - x-y+3=0 - equation 1

if  the  numerator and denominator is decreased by 1 then

x-1/y-1=1/2 : - 2(x-1) = 1(y-1) : - 2x-y-1=0 -equation 2

then equation 1 = equation 2

x-y+3=2x-y-1 : - x=4

from  the equation 1 

x-y+3=0 : - 4-y+3=0 : - y=7

there fore the fraction is 3/7 

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
