Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
Answer: Option B- The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60
4e - 6e - 5 = 15
Begin by combining like terms:
4e - 6e = -2e.
The equation is now simplified.
Now, it is time to find the value of the variable.
-2e - 5 = 15
Step 1: Add 5 to both sides.
We now have -2e = 20.
Step 2: Divide both sides by -2 to isolate the variable.
-2e / 2 = e; 20 / -2 = -10.
Therefore, e = -10.
