Answer: {y,x} = {4,2} ) ) ) )4
Step-by-step explanation: y
[2] y = -2x + 8
// Plug this in for variable y in equation [1]
[1] (-2x+8) - x = 2
[1] - 3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
y = -2x+8
x = 2
// Use the x value to solve for y
y = -2(2)+8 = 4
Solution :
{y,x} = {4,2}
-20 because 40 is a positive and spent is negative
Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 
and ( )² = 12
2² + (
)² = 4 + 8 = 12
Thus the triangle is right → C
Answer:
It is the third one because of formula I² + 2I*II + II²
In your case I = 4x and II = 3
Answer:
Lindsay owns 12 books
Step-by-step explanation:
1/3x:Lindsay
x:Destiny
1/4x: Henry
1/3x+1/4x+x=57
4/12x+3/12x+x=57
7/12x+x=57
19/12x=57
x=57*12/19
x=36
1/3x=36/3
1/3x=12
