Step-by-step explanation:
Answer:
d. The equation has one solution and there is not enough information to determine the direction of the parabola.
Step-by-step explanation:
For a general quadratic equation
y = ax² +bx +c
the solution is

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.
D tells us whether there are
- two different real solutions
- two identical real solutions ("one solution")
- two complex solutions.
If D= 0,

and there are two identical solutions ("one solution").
The direction of the parabola depends on the sign of a.
That information is not given, so we cannot determine the direction of the parabola.
Answer:
x<−8 or x>−4
Step-by-step explanation:
−x>8 or −x<4
We know either −x>8 or −x<4
−x>8(Possibility 1)
−x
−1
>
8
−1
(Divide both sides by -1)
x<−8
−x<4(Possibility 2)
−x
−1
<
4
−1
(Divide both sides by -1)
x>−4
Answer:
15 and 21
Step-by-step explanation:
Given the n th term formula
T = 2n + 5
To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula
= (2 × 5) + 5 = 10 + 5 = 15
= (2 × 8) + 5 = 16 + 5 = 21
It is C.
First, you have to do the problem in the (), so 3*4 = (12). 12 - 2 is 10. Next, you do the other () which is 5 + 7 which is 12. 12 + 10 = 22
