Answer:
No real roots
Step-by-step explanation:
Given
7x² + 5x + 1 = 0 ← in standard form
with a = 7, b = 5, c = 1
To determine the nature of the roots use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then the roots are not real
Here
b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3
Thus the 2 roots are not real
Answer:
$2.85
Step-by-step explanation:
First, add the bill up ($8.70 + $10.30 = 19). So now you need to find what 15% of $19 is...To find the percentage of something you need to turn it into a decimal, 0. (whatever the percentage number is). So in this case, 19 times 0.15, which is a tip of $2.85.
