P(x)=R(x)-C(x)
=(-0.5x²+800x-100)-(300x+250)
=-0.5x²+800x-100-300x-250
=-0.5x²+800x-300x-100-250
=-0.5x²+500x-350 (2)
Hello! I've noticed that this question hasn't been answered in a week, by now. If you still need the answers, here they are.
5) you need to use the Pythagorean theorem to get the answer. I got C) 5x + x<span>√17
6) Your answer choice would be C) 4</span><span>√6/ 3
Good luck. x</span>
Current Account Balance = $1,624.35
Initial Deposit = $975
Interest Rate (Simple) = 3.7% simple interest
Interest Earned = Current Account Balance - Initial Deposit
⇒ Interest Earned = $1,624.35 - $975
⇒ Interest Earned = $649.35
Now the Formula for Simple Interest is:
Simple Interest = ×
, where P is the initial deposit, R is the rate of interest and T is the time period
⇒ 649.35 = 
⇒ T = 
⇒ T = 18
Hence, Jeremiah has had the account for 18 years.
Flip over the second fraction
2 3/5= 13/5 ( Multiply the whole number with the denominator, 2*5=10 then add the numerator 10+3=13
-3 3/4= -15/4
13/5 * -4/15= -52/75
Answer :-52/75
Answer:
x = -2
Step-by-step explanation:
To find out what x is you have to use inverse operation.
Minus the 8 on both sides.
5x = -10.
Divide both sides by 5 to find out what x is on it's own.
x = -2.
Hope this helps :)
