Answer:
84
Step-by-step explanation:
Let the first digit = x
Let the second digit =y
x + y = 12
x + 4 = 3*y
===========
From the second equation, we learn that x = 3y - 4
Put that into the first equation.
3y - 4 + y = 12 Combine the left side
4y - 4 = 12 Add 4 to both sides
4y = 16 Divide by 4
4y/4 = 16/4
y = 4
=================
x + 4 = 12
x + 4 - 4 = 12-4
x = 8
So the number is 84
Answer:
y=3x-1
Step-by-step explanation:
start at (-1,-4) and go up 6 and over 2, thats your slope or m.
the y intercept is -1
Answer:
508 because you need to add up all the sides
Answer:
2 and -10
Step-by-step explanation:
let the two integers be x and y.
so, x+y=-8---‐-------(1)
and,
x=y+12-------‐-----(2)
from (1) and (2),
(y+12)+y=-8
or, 2y=-8-12
or, y=-20/2
or, y=-10
substitutting the value of y in (2),
x=-10+12=2
therefore the required integers are 2 and -10.
