Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal.
Identity - a * b = ab
Time to run 1 mile * number of miles run must be 30 minutes or less
Time to run a mile is 8
Used m = number of miles ran
8m <= 30
<= is less than or equal to
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
