1] y - 3x = -8
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}
Answer:
12600
Step-by-step explanation:
5% of 12000 is 600 so just add them
Answer:
not a solution
Step-by-step explanation:
y < 7x + 8
Substitute (2-,-6) into the inequality
-6 < 7(-2) +8
-6 <-14+8
-6 <-6
This is not true because they are equal not less than
A cube because it has 6 faces/sides and 12 edges.
The real answer is 1 2 5 i had this one
