You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113
Best of Luck!
Answer: 21 miles
Step-by-step explanation:
Here's the remainder of the question:
Write an equation to determine the distance in miles x between the airport and Ann's home.
We are informed that the taxi fare was $2.10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10, this can be expressed into an equation as:
(2.10 × x) + 5 = 49.10
2.10x + 5 = 49.10
2.10x = 49.10 - 5
2.10x = 44.10
x = 44.10 / 2.10
x = 21
The distance between the airport and Ann's home is 21 miles.
