Answer:
The answer is -2 & 3
Step-by-step explanation:
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?
Answer:
x = -3
Step-by-step explanation:


Add 2/3 x to both sides: 
Subtract 8 from both sides: 
Multiply both sides by 3: 
Divide both sides by 11: 
Therefore, point of intersection between both lines is at point (-3, -1)
FG = FE
3n - 4 = n + 8
2n = 12
n = 6
FG = 3(6) - 4
FG = 18 - 4
FG = 14
answer
14
0.4x 0.4x 0.4 = (0.4)^3
Exponential form = (0.4)^3
