tion x over 40 EndFraction = StartFraction 10 over 8 EndFraction the same?
Answers
A because both result in the equation 8 x = 400, which simplifies to x = 5
B because both result in the equation 8 x = 400, which simplifies to x = 50
C because both result in the equation 40 x = 80, which simplifies to x = 2
D because both result in the equation 40 x = 80, which simplifies to x = 20

What is the rate of change between (29,9) and (33,10)?
Tema [17]

Answer:

\frac{1}{4}

Step-by-step explanation:

The rate of change is a measure of the slope

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)

m = \frac{10-9}{33-29} = \frac{1}{4} ← rate of change
