Y = mx + b

7x + 8y = -12
Subtract 7x from both sides
8y = -7x - 12
Divide each side by 8
y = -7/8x - 12/8
Simplify
y = -7/8x - 3/2

So besides simplifying, if I’m doing this correctly, it should be correct.

Given a regular square pyramid with RS = 6 and PX = 4, find the following measure.<br><br> PY =

Dennis_Churaev [7]

Answer:

$PY=5\ units$

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

$PY^{2}=PX^{2}+XY^{2}$

In this problem we have that

$XY=RS/2=6/2=3\ units$

$PX=4\ units$

substitute

$PY^{2}=4^{2}+3^{2}$

$PY^{2}=25$

$PY=\sqrt{25}\ units$

$PY=5\ units$
