Answer:
Step-by-step explanation:
hello :
y= 5x + 9
y = -x +3
so : 5x+9 = -x+3
5x+x= 3-9
6x=-6
x=-6/6 = -1
The formula for the volume of a cylinder is V=pi*r^2*h
Since the diameter is 6.8, the radius must be 3.4 (6.8/2)
We can then plug in the given values to solve for the volume
V=3.14*3.4^2*4
V=3.14*11.56*4
V=145.2 so B
Hope this helps

Answer:
Simplifying
6x + -2y = 30
Solving
6x + -2y = 30
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
6x + -2y + 2y = 30 + 2y
Combine like terms: -2y + 2y = 0
6x + 0 = 30 + 2y
6x = 30 + 2y
Divide each side by '6'.
x = 5 + 0.3333333333y
Simplifying
x = 5 + 0.3333333333y
