Answer:

<h2><u>#1: </u></h2>

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:  

4 lbs / $3  = 1lb / x     = cross-multiply  

4x = 3   =  divide by 4  

x = 3/4 dollars = $.75 per pound

----------------------------------------------------  

<h2><u>#2: </u></h2>

The point (8,6) means that 8 lbs. of potatoes = $6.

Hope this helps!

Answer:

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

 

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:

4 lbs / $3  = 1lb / x       cross-multiply

4x = 3      divide by 4

x = 3/4 dollars = $.75 per pound

 

The point (8,6) means that 8 lbs. of potatoes = $6.

DIA [1.3K]

Answer:

y=-4/3x-8/3

Step-by-step explanation:

Use the slope formula y2-y1/x2-x1

Finding the slope, 4-(-4)/-5-1 = 8/-6 = -4/3

y=-4/3x + b

Substituting,

-4=-4/3+b

-12/3+4/3=b

b=-8/3

y=-4/3x-8/3

CALCULUS RELATED RATES: A 20 foot ladder is leaning against a wall. The base of the ladder is placed 6 feet from the bottom of t
Daniel [21]

Answer:

2.17ft/s

Step-by-step explanation:

Look at the sketch of ladder at the beginning and after 3 seconds it starts to fall,

Distance of ladder from the wall 3 seconds after ladder starts to fall                                       =  Initial distance+  Velocity× time

= 6 + 2×3

= 12ft

Use trignometry to find out the speed of the top of ladder

cosθ= 12/20

θ= 0.825 rad

tan θ= v/2

v= 2.17ft/s
