I hope im right!!
Answer:
6x2 + 23x + 7 = 0
Factorization:
(2x + 7)(3x + 1) = 0
Solutions based on factorization:
2x + 7 = 0 ⇒ x1 = −7
2
= −3.5
3x + 1 = 0 ⇒ x2 = −1
3
≈ −0.333333
Extrema:

Answer:
3.14
Step-by-step explanation:
Answer:
(21, 17 )
Step-by-step explanation:
Using the midpoint formula and equating to the coordinates of the midpoint.
Let endpoint 2 have coordinates (x, y ), then
0.5(x - 3) = 9 ( multiply both sides by 2 )
x - 3 = 18 ( add 3 to both sides )
x = 21
and
0.5(y - 5) = 6 ( multiply both sides by 2 )
y - 5 = 12 ( add 5 to both sides )
y = 17
endpoint 2 = (21, 17 )
