Question

x: number of minutes
y: height above ground
find rumi and noams height after 2 minutes.
rumi: ? feet noam: ? feet
(chart: noam: y = 8x + 10; rumi: y = 10x, x-axis: number of minutes, y-axis: height above ground)

Explanation:

Step1: Calculate Rumi's height

Rumi's height is given by the equation \( y = 10x \). Substitute \( x = 2 \) (minutes) into the equation.
\( y = 10\times2 = 20 \)

Step2: Calculate Noam's height

Noam's height is given by the equation \( y = 8x + 10 \). Substitute \( x = 2 \) (minutes) into the equation.
\( y = 8\times2 + 10 = 16 + 10 = 26 \)

Answer:

Rumi: 20 feet, Noam: 26 feet
