6x - 11 - 2x = -7
4x - 11 - = -7
4x = 11
X= 2
12- 11 -4 -3y = -7
-3 -3y = -7
-3y = -4
Y = -1
It should be 2,-1
Answer: 
Step-by-step explanation:
Volume is base* height
the base a the circle
area of a circle: 
the radius is 1/2 of the diameter, so it's 4
To find the volume I multiplied it by 8 (height)
Answer:
As x increases , y decreases then increases
Step-by-step explanation:
There are two situation
1> when x < 0
2> when x>= 0
let see
when x < 0
we see that as value of x moves from -ve value towards zero (i.e x is increasing) then value of y is decreasing( value of x has moved from positive side of y( above x-axis) towards negative side of (below x-axis)\
Thus, we can say that
for x < 0
As x increases , y decreases
________________________________________
when x>= 0
we see that as value of x moves from 0 towards +ve value(i.e x is increasing) then value of y is increasing( value of x has moved from negative side of y( below x-axis) towards positive side of (above x-axis)\
Thus, we can say that
for x >= 0
As x increases , y increases
_________________________________________
combining both observation it can be said that
As x increases , y decreases then increases which is equal to fouth option
