Answer:
x=3h+k/a-3
Step-by-step explanation:
Attached is the solution. I hope this helps you!!
This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
X and y
x=2y+9
x-y=22
*x is the larger number*
plug in x to solve for y
2y+9-y=22
y+9=22
-9 both sides
y=13
plug in y and solve for X
x=2 (13)+9
x=26+9
x=35
