<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155

Answer:
The stock Norman purchased increased in its value by 25%.
Step-by-step explanation:
Original Value of the stock = $ 420
New(Current) value of the stock = $ 525
We have to find the percentage change in the value of stock. The formula to calculate the percentage change is:

Substituting the given values into this formula results in:

A positive value of Percentage Change indicates a growth. This means that the stock Norman purchased increased in its value by 25%.
Answer:
3a^4
Step-by-step explanation:

Hope this helps!
A]<span>Given that y varies jointly with w and x and inversely with z and y = 175 when w = 5, x = 20 and z = 4.
then
y=kwx/z
where k is the constant or proportionality given by:
k=yz/wx
but
y=175, when w=5, x=20, z=4
hence
k=(175*4)/(5*20)
k=7
Thus the equation is:
y=(7xw)/z
b]</span><span>find y when w = 2, x = 24 and z = 6.
y=(7*2*24)/6
y=336/6
y=56</span>
