(1, 1), 5 + 2 = 7, not that hard!
Answer:
x = 3/4 + (3 sqrt(5))/4 or x = 3/4 - (3 sqrt(5))/4
Step-by-step explanation:
Solve for x over the real numbers:
8 x^2 - 12 x - 23 = -5
Divide both sides by 8:
x^2 - (3 x)/2 - 23/8 = -5/8
Add 23/8 to both sides:
x^2 - (3 x)/2 = 9/4
Add 9/16 to both sides:
x^2 - (3 x)/2 + 9/16 = 45/16
Write the left hand side as a square:
(x - 3/4)^2 = 45/16
Take the square root of both sides:
x - 3/4 = (3 sqrt(5))/4 or x - 3/4 = -(3 sqrt(5))/4
Add 3/4 to both sides:
x = 3/4 + (3 sqrt(5))/4 or x - 3/4 = -(3 sqrt(5))/4
Add 3/4 to both sides:
Answer: x = 3/4 + (3 sqrt(5))/4 or x = 3/4 - (3 sqrt(5))/4
Hello!
I would be more than happy to help!
So to find the balance use this equation.
Balance = Credit- Debit
In other words, to find BALANCE... You Subtract Debit from Credit
whats my credit? 84$
Whats my debit? 29$
Whats my balance? Lets find out! How? Well, lets subtract my credit (84) from my debit (29).
84-29= 55
Balance =55
Hope this helped!
345= 3 hundreds, 4 tens, and 5 ones
391= 3 hundreds, 9 tens, and 1 one
You can use the model I attached to help u see it better.
Hope this helps!
Answer:
58+40e−t/2458+40e−t/24
step by step explanation:
Normally, the temperature of a corpse is the temperature of the surrounding environment.
This is done by losing or gaining heat to equilibrate to that of the surrounding.
Let's assume that the final temperature of the corpse is after t hrs.
Then the temperature of the surrounding in degree Fahrenheit is equal to 58+40e−t/2458+40e−t/24
