Answer:
one solution : (-2 ; -7)
Step-by-step explanation:
hello :
x - y = 5
....(*)
- 3 x + y = - 1 ....(**)
by (*) : y=x-5
by(**) : y = 3x-1
3x-1 = x -5
3x-x=-5+1
2x= -4
x= -2
but : y = x-5 so : y= -2-5=-7
one solution : (-2 ; -7)
Just use distance formula for each point and plug it in p=a+b+c
collect the like terms
4x - 9 = 6-x
4x + x= 6+9
and then complete the equation
5x = 6 + 9
5x = 15
x = 15 ÷ 5
x = 3
Answer: I(x)=12x
Step-by-step explanation:
Let I represent the total money earned
Let x represent the number of toys sold
Since each toy is 12 dollars, then the company will earn 12 dollars for each toy that is sold.
Therefore, the equation is,
I(x)=12x
