Answer:
Step-by-step explanation:
hello :
a= 1 b= -4
the vertex is : ( -b/2a ; f(-b/2a)
-b/2a = - (-4)/2 = 2
f(2) = (2)²-4(2)-5 = 4-13= -9
the vertex is : (2 ; -9)
I think it would be 9 miles.
C will be the rightful answer
Answer: sally initially has $240, Tom initially has $180.
Let initial amount of money sally has = x
Then, initial amount tom has = 75% * x = 0.75x
Now to present,
Amount sally has = x -120
Amount tom has = [x - 120] + [50% * (x-120)]
= x - 120 + 0.5x - 180
= 1.5x - 180
Since Tom didn't spend, it means this is the same amount tom has then we equate both equations.
0.75x = 1.5x - 180
180 = 0.75x
x = 240
Therefore, initial money of sally of sally = $240
Initial money of tom = 240 * 0.75 = $180.
y-2 = 3/10(x+3)
3y = 10
y = 10/3
looking for perpendicular so slope = 3/10
using the given point
