16
Step-by-step explanation:
1. Use a vertical number line to count how many spaces are between -6 and 10.
Answer:
The first six terms of this arithmetic sequence are: 30, 32, 34, 36, 38, 40
Step-by-step explanation:
The nth term of an arithmetic sequence is given by:
In which d is the common difference, that is, each term is increased by d.
d = 2, Po= 30
First term is 30, each consecutive is increased by 2. So
30, 32, 34, 36, 38, 40

Step-by-step explanation:
We can simplify this fraction down further by divide both numerator and denominator by 2:
10/2 = 5
12/2 = 6
5/6 will be equivalent to 10/12
Answer: B) 0 real roots
---------------------------------------
The general rule is...
if D > 0, then you have two different real roots (see note below)
If D = 0, then you have exactly one real root
If D < 0, then you have no real roots (the two roots are imaginary/complex)
where D is the discriminant found by the formula
D = b^2 - 4ac
Note: If D is also a perfect square, then the two real roots are also rational. This assuming that a,b,c are rational.
