Which equation is correct regarding the diagram of circle
O?
OmZXZY = {(a + b)
mZXZY = {(a - b)
OmZXoY = {(a + b)
©mXoy = {(a - b)

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
