Answer:
This is known as <em>substitution property</em>. In that problem you substituted 5 for b, which shows that this equation illustrates the substitution property.
Answer:
13/15 > 4/5 is a true stament.
Step-by-step explanation:
The left side is 0.86 repeating turned into a decimal. which means 0.86 is greater than the right which the right is 0.8 turned into a decimal. which in this case this means that the given stament is always true.
You use the discriminant of the quadratic formula which is
Using the values of the given quadratic formula you will find that
If the discriminant equals less than 0 you have no real roots(imaginary roots).
If it equals exactly 0, you have 2 real equal roots.
If it is more than 0, then you have two different real roots.
Therefore the quadratic function
Will have two real roots.
Answer:
Semicircle
Step-by-step explanation:
As we can see, the arc is bounded by the chord MO
since the chord passes through the center of the circle, we have it that the chord is a diameter
Mathematically, an arc bounded by a diameter represents half of a circle
So we can conclude that the arc MNO in circle C is a semicircle
