Answer:
The largest root of this equation is 12
Step-by-step explanation:
To find this, first factor the equation.
x^2 - 13x + 12 = 0
(x - 12)(x - 1) = 0
Now set each parenthesis equal to 0 to get the roots.
x - 12 = 0
x = 12
x - 1 = 0
x = 1
The larger of those two is 12 and that is the answer.

Answer:
This would be a $150 increase
Step-by-step explanation:
In order to find the increase in price, we need to determine the overall costs for buying and selling. In order to do that, multiply the number of shares by the cost per share.
12 * $27 = $324
12 * $39.50 = $474
Now to find the difference, we subtract the old amount from the new amount.
$474 - $324 = $150
Answer:
a) $520
b) $580
c) Interest amount is same each year
Step-by-step explanation:
Given - Georgie put $500 in her savings account, earning interest at a rate of 4% each year. She did not make any more deposits or withdrawals.
To find - a) How much money was in the account after one year?
b) How much money was in the account after 4 years?
c) Was the amount of money earned in interest the same or different each year?
Proof -
Here given that,
Principal amount = $500
rate of interest = 4% = 4/100 = 0.04
Now,
a)
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(1)]
= 500 [ 1 + 0.04] = 520
⇒Amount = $520
b)
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(4)]
= 500 [ 1 + 0.16] = 580
⇒Amount = $580
c)
In 2nd year,
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(2)]
= 500 [ 1 + 0.08] = 540
⇒Amount = $540
Now,
Interest in 1st year = 520 - 500 = 20
Interest in 2nd year = 540 - 520 = 20
So,
The interest amount is same each year
The given expression is:
(x/2) + 5
Let's look at each terms separately:
x/2 means that you you're getting half the value of a number
+5 means that you are adding 5
Combining both, you can conclude that you are adding 5 to half a certain given number.
Comparing this with the choices, the correct choice would be:
C. five more than half a number.
