Could you explain your answer?
If it's wrong it should be report called "improper answer."

Answer:
A
Step-by-step explanation:
Write each parabola in standard form.
f(x) = x²
f(x) = (x − 0)² + 0
For p(x), complete the square.
p(x) = -50 + 14x − x²
p(x) = -(x² − 14x + 50)
p(x) = -(x² − 14x + 49 + 1)
p(x) = -(x² − 14x + 49) − 1
p(x) = -(x − 7)² − 1
The transformation from f(x) to p(x) includes a reflection about the x-axis, a shift right 7 units, and a shift down 1 unit.
The answer is A.

Answer:

0 = -6x
0 = x

(0,-12)
Step-by-step explanation:
x - boat speed; y - current speed; Path = 336:2 = 168 miles
1) 12 * (x + y) = 168; -> x + y = 14;
2) 14 * (x - y) = 168; -> x - y = 12;
1) x = 14 - y;
2) (14 - y) - y = 12;
14 - 2y = 12;
2y = 2;
y = 1 mph
x = 14 - 1 = 13 mph
Answer:
Boat speed = 13 mph
Current speed = 1 mph
The answer would be 9 because
No.5=1/3x=21
So x is twenty one21
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
