Answer:
the center is (0,0) and the radius is 3
Step-by-step explanation:
Let's look at the graph... its center will be at (0,0), and the radius = 3
Imagine any line drawn through the center will "split" the circle in half, and can be called a line of symmetry.
Answer:
The terms are x, -4, 3 and -5x.
The like terms are x and -5x, as well as -4 and 3.
Step-by-step explanation:
Like terms are terms that have the same variables and powers.
Answer:
A, in quadrant II, or 2
Step-by-step explanation:
Answer:
1/2y-4=x
Step-by-step explanation:
Y=3+2x+5
add 3 and 5
y=8+2x
subtract 8
y-8=2x
divide by 2
1/2y-4=x
Answer:
16 + sqrt(128)
Step-by-step explanation:
find the lengths of all 3 sides:
the side from (-9,8) to (-9,16) will be 16-8=8 (x stays constant)
The side from (-9,8) to (-17,8) is 8 (-9- (-17)=8)
The side from (-9,16) to (-17,8) will be found from the distance formula
d=sqrt((-17-9)^2 + (8-16)^2))
= sqrt(128)
So the perimeter will be these 3 numbers added together
P=sqrt(128) + 8 + 8
= 16 + sqrt(128)
which can simplify to:
= 16 + 4sqrt(8)
= 16 + 8sqrt(2) = 8+ sqrt(2)
