Answer:
x = 38
Step-by-step explanation:
using the law of logarithms
•
x = n ⇔ x =
, hence
(2x - 12) = 3 ⇒ 2x - 12 =
= 64
add 12 to both sides
2x = 76 ( divide both sides by 2 )
x = 38
Answer:
Step-by-step explanation:
-10 ( y-4) + 3y = 5 <--- substitute the value of x into first equation
-10y + 40 + 3y = 5
-7y + 40 = 5
-7y = -35
y= 5
x = 5 - 4
x = 1

Answer:
<h2>x = -5.24 or x = 3.24</h2>
Step-by-step explanation:

Answer:
Let the two numbers be x and y.
Then x + y = 20, and y = 20 - x.
Their product is what you get when you multiply the two numbers together, in other words xy, or x(20 - x). You can expand this out to get 20x - x².
The product of the two numbers will be maximum at the value
