Answer:
y=-4/13x-28/13
Step-by-step explanation:
m=y2-y1/x2-x1
m=-4-0/6-(-7)
m=-4-0/6+7
m=-4/13
y-y1=m(x-x1)
y-0=-4/13(x-(-7))
y-0=-4/13x-28/13
y=-4/13x-28/13
The correct answer to your question is number 2
Answer:
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Step-by-step explanation:
Let the age of Alicia be x
Let the age of Quentin be y
Let the age of Rosalyn be z
If the sum of the siblings’ ages, in years, is 48 then;
x+y+z = 48.... 1
If Rosalyn is two years older than Quentin then;
z =y+2 ..... 2
Also if Quentin is four years younger than Alicia then;
y = x-4 ... 3
From 3:
x = y+4 ... 4
Substitute 2 and 4 into 1 to have:
y+4+y+y+2 = 48
3y + 6= 48
3y = 48-6
3y= 42
y = 14
Since x= y+4
x = 14+4
x = 18
Since z = y+2
z = 14+2
z = 16year
This means that;
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Answer:
1 ≤ x < 7
