Answer:

<h2><u><em>P = 16</em></u></h2><h2><u><em>C = 24-P = 8</em></u></h2>

Step-by-step explanation:

Heads: P + C = 24

C = 24 - P

Legs: 4P + 2C = 80

Substitute, from heads: 4P + 2 (24 - P) = 80

4P + 48 - 2P = 80

2P = 32

<u><em>P = 16</em></u>

<u><em></em></u>

<u><em>C = 24-P = 8</em></u>

====================

Check:

P + C = 16 + 8 = 24

4P + 2C = 4(16) + 2(8) = 64 + 16 = 80

Can someone help right away!! please!!
larisa [96]

Answer:

y = - 2x + 1

Step-by-step explanation:

Substitute an x value from the table into the equation

x = 1 : y = - 2(1) = - 2 ← require to add 1 to obtain y = - 1

x = 4 : y = - 2(4) = - 8 ← require to add 1 yo obtain y = - 7

Then equation describing the relationship is

y = - 2x + 1

The formula v =sqrt 64h can be used to find the velocity, v, in feet per second, of an object that has fallen h feet. Find the v
miskamm [114]
To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:

 1. You have that the<span> formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:

 v=</span>√(64h)
<span>
 2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:

 v=</span>√(64h)

 h=23 feet

 v=√(64)(23)
 v=√(1472)
 v=8√23
 v=38.37 feet per second

 3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
