The difference of two negative integers is 8 and their product is 48.Find the two integers.

The answer is 12 and 4

Step-by-step explanation:

1st equation: -x-(-y)=8

2nd equation: (-x)(-y)=48

-x-(y)=8

-x+y+8

y=x+8

-x(x+8)=48

-x^2-8x=48

Multiply -1

x^2+8x=-48

x^2+8x+48=0

(x+12)(x-4)=0

x=-12

x=4

Check:

-(-12)-(4)=8

12-8=8

8=8

(-12)(-4)=48

48=48

the correct answer is d

hope this

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
