4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
Answer:
1. (-2,-7)
2. (3,-9)
3. (7,-2)
4.(-3,9)
Step-by-step explanation:
Since the reflection is across the x-axis, the y-coordinate will be flipped.
Example: (-7,4) would become (-7,-4)
HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.
Example: (-7,4) would become (7,4)
Answer:
$246.42
Step-by-step explanation:
13.69(4+4+4+4) + 27.38
13.69(16) + 27.38
219.04 + 27.38
246.42
You should make $246.42.
