Connor and Pilar are in a rock-climbing club. They are climbing down a canyon wall. Connor starts from a cliff that is 200 feet above the canyon floor and climbs down at an average speed of 10 feet per minute. Pilar climbs down the canyon wall as shown in the table. Time in minutes 0 1 2 3
Pilar's height (feet) 242 234 226 218

Part A: Who is descending (going down) faster per minute? How much faster is that person going?

Part B: Write a function to model Pilar's descent as shown in the table. Identify the rate of change and the initial value.

Part C: Will there be anytime that Connor and Pilar will meet on their way down? Explain your reasoning.

Part D: Lydia is also a member of the rock-climbing club. The graph represents her descent. Does this graph represent a linear or non-linear function? Justify your answer with information from the graph.

step-by-step explanation:

1/4 = .25 / 25%

the answer is the third / last answer

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
