Answer:
its yes I think
Step-by-step explanation:
ummm I think its yes it's hard to explain
Answer:
x=1
y=−2
z=5
(heres how i got the answer)
Step-by-step explanation:
x+2y+3z=12
x−3y+4z=27
−x+y+2z=7
Solve x+2y+3z=12 for x.
x=−2y−3z+12
Substitute −2y−3z+12 for x in the second and third equation.
−2y−3z+12−3y+4z=27
−(−2y−3z+12)+y+2z=7
Solve equations for y and z respectively.

y=−2
Substitute −2 for y and 5 for z in the equation x=−2y−3z+12.
x=−2(−2)−3×5+12
Calculate x from x=−2(−2)−3×5+12.
x=1
The system is now solved.
x=1
y=−2
z=5
First, we calculate the radius of the circle.
radius=diameter / 2
radius=44 ft / 2=22 ft.
Second; we calculate the area of a circle.
area of a circle=πr²
area of a circle=π(22 ft)²=484π ft²
Remember: 22²=22 * 22 =484
Answer: B) 484π ft²
Up is the y value and left is the x value.
In the point ( t,u) t is the x value and u is the y value.
Moving to the left, you subtract the value and moving up you add the value.
The answer would be (t, u) → (-t – 3, u + 8)
