Hello,
y=-x²+4x+5=-(x²-4x+4)+5+4=-(x-2)²+9
Answer A (2,9)
He will be charged for 551 miles.
30283-29582=701 miles traveled in the rental vehicle.
150 of those miles are free; 701-150 = 551 miles he will be charged for.
<span>3 times the complement of an angle is 30 more than the supplement of the original angle.
so if the angle is x then its complement is 90-x & supplement is 180-x
so 3(90-x)=(180-x)+30
or 270-3x=210-x
or 3x-x=270-210
or 2x=60
or x=30 the original angle

Answer:
15.00+(0.25)x=c

Answer:
x = 22, y = -4
Step-by-step explanation:
x + 6y = -2 --- Equation 1
-x = 3y - 10 --- Equation 2
Equation 2 ×(-1): x = -3y + 10 --- Equation 3
Substitute x = -3y + 10 into Equation 1:
x + 6y = -2
-3y + 10 + 6y = -2
3y + 10 = -2
3y = -2-10
= -12
y = -12 ÷ 3
y = -4
Substitute y = -4 into Equation 3:
x = -3y + 10
x = -3(-4) + 10
= 12 + 10
x = 22
