X+y = 6
-y+2+y = 6 ... replace x with -y+2
(-y+y) + 2 = 6
(-1y+1y) + 2 = 6
(-1+1)y + 2 = 6
0y + 2 = 6
0+2 = 6
2 = 6 ... this equation is false
Since the last equation is false, this means that no matter what we pick for x and y, there is no solution. This system is inconsistent. The two lines are parallel (they never intersect to form a solution)
Answer:
To be complement sum of angle must be 90°
But to be supplement sum of angle must be 180°
Step-by-step explanation:
Answer:
x = 2.5
Step-by-step explanation:
hypotenuse^2 = side^2 + side^2
(x+4)^2 = x^2 + (6)^2
x^2 + 8x + 16 = x^2 +36
we get,
8x = 36 - 16
x = 20/8
x = 2.5
Answer:
7
Step-by-step explanation:
The 'braces' don't really matter in this equation, it is all multiplication, just open those bad boys up and you get 4*2*7=4*2*? Now it is much easier, just take the value missing from the left side and you find it is 7!
