Answer: -x/2 + 1
Step-by-step explanation:
write t in terms of x
x = 2t
t = x/2
substitute t in y
y = 1 - t
y = 1 - x/2 or -x/2 + 1
Answer:
B
Step-by-step explanation:
Initial mean = 156, Changed mean = 163.92
So, mean increases. Only condition that satisfies this is B.
To find area, you multiply length * width. There are 4 sides on a number, so we need to have a equation like this. x * x * y * y = 12cm. If we do 4 * 4, we get 8. We could also use 2 * 2 = 4. 8 + 4 = 12. So, width = 8, and length = 4.
Hope this helps! ☺♥

If you look closely.. You can see that one is longer than the other
Answer:
x= -1; y= -2
Step-by-step explanation:
A: 6x+4y= -14
B: -x-5y=11
6B is : -6x-30y=66
A+6B is : -26y=52
so y= -2
so A becomes : 6x+4.(-2)= -14
so x= -1
