Write an expression to represent Vivian's change in elevation from -9.6 feet at the bottom of the Ferris wheel to 12.3 feet at
Effectus [21]

Answer:

<h2><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em></h2>

<em />

Step-by-step explanation:

Give the distance covered by Vivian at the bottom of the elevation to be -9.6 feet and the distance covered by Vivian at the top of the elevation to be 12.3 feet, Vivian's change in elevation will be expressed as the difference in the elevation at the bottom and the elevation at the top.

Let the initial elevation Ei = -9.6 feet

Final elevation Ef = 12.3 feet

Change in elevation ΔE = Ef - Ei

Change in elevation ΔE =12.3 - (-9.6)

Change in elevation ΔE = 12.3 + 9.6

Change in elevation ΔE = 21.9 feet

<em>Hence the expression to represent Vivian's change in elevation from -9.6 feet at the bottom of the Ferris wheel to 12.3 feet at  the top is </em><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em>

Use the point-slope form linear equation given.
Agata [3.3K]

y-3=3(x+1)

opening the bracket

y-3=3x+3

y=3x+3+3

equation of the line in the form y=mx+c;

y=3x+6

therefore gradient=3

parallel lines have same gradient therefore gradient of the other line is 3

y--3/x-0=3

y+3=3(x-0)

y+3=3x-0

y=3x-3.
