XYZ ABC XYZ ABC have a nice day
9.) a: The relationship between x and y is linear, as the line is straight and it passes through the orgin, and the values are proportional.
b: According to the graph, the drill team will have to pay $72 if they purchase 12 uniforms.(y=60x; 12=60(12))
10.) The relationship between x and y is nonlinear, as the line is not straight, nor pass through the orgin, which makes it also nonproportional.
Answer: x² + y² = 25
Step-by-step explanation: As we have x²+y²=25 (A) as options,
x-y=1 (B)
x+y=25 (C)
x²+y²=5 (D)
We can rule out B and C as they are not circles. Circles must be
(x - xc)² + (y - yc)² = r². They must have index 2.
We have then A or D.
As the circle must pass through (3,4), we can substitute as x=3 and y=4
(A) 3² + 4² = 9 + 16 = 25 ok
(D) 3² + 4² = 9 + 16 = 25 ≠ 5
So, it is A, x² + y² = 25
for x=2....value will be 53
for x=7.....value will be 33
