Answer:
x² + 1 = 0
Step-by-step explanation:
You can form any with discriminant negative (B²-4AC < 0)
An example could be:
x² + 1 = 0
x² = -1 which has no real roots/solutions

Step-by-step explanation:
The balance in the account after 13 years is $8233.79.
<h3>Compound interest: Calculating balance in an account</h3>
From the question, we are to use the compound interest formula to compute the balance in the account
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $7000
r = 3.3%= 0.033
n = 1
t = 13
Putting the parameters into the formula
A = P(1 + r/n)^nt
A = 7000(1 + 0.033/1)^(1×5)
A = 7000(1 + 0.033)^5
A = $8233.79
Hence, the balance is $8233.79

Answer:
It'll have an open circle on both 7 and 21, with a line connecting.
Which is none of the options, unless one isn't shown?
Step-by-step explanation:
-23 > -4x + 5 > -79
So:
-23 > -4x + 5
-23 - 5 > -4x
-4x < -28
x > -28 / -4
x > 7
-4x + 5 > -79
-4x > - 79 - 5
-4x > -84
x < -84 / -4
x < 21
