Answer:
<h2>No solution : 0= -5</h2>
Step-by-step explanation:


1.
the line of symmetry is x=2, means that the x coordinate of the vertex is x=2.
the point x=2 is the midpoint of the roots

and

.
so


Remark: in the x-axis, if c is the midpoint of a and b, then

2.
since

and

are roots

and

3.
equalizing:



in the left side factorize a, in the left side factorize 8:
![a[(x_1)^{2}-(x_2)^{2}] =8(x_1 -x_2)](https://tex.z-dn.net/?f=a%5B%28x_1%29%5E%7B2%7D-%28x_2%29%5E%7B2%7D%5D%20%3D8%28x_1%20-x_2%29)
in the right side use the difference of squares formula:

simplify by


substitute

with 4:

a=2
Answer: C)2
Answer:
14 mi per hour
Step-by-step explanation:
14x6 equals 84
Not necessarily the case, because the function tends to infinity when sin(x) approaches 0 and it is 1 (minimum value) when sin(x) = 1. Look at the picture to know what it looks like.
First, we can do distributive property.
-3(n + 8) = 15
-3 x n = -3n, -3 x 8 = -24
So we have, -3n + -24 = 15
Minus -24 on both sides of the equal sign.
-3n + -24 - -24 = 15 - -24
-3n = 39
Divide 3 on both sides.
-3n/-3 = 39/-3
n = -13
Hope i helped!! :D
