It's an upside (-) down parabola. The axis of symmetry is the x coordinate of the vertex.
you can easily find this using formula: x= -b/2a
for parabola: ax² + b + c = 0
x = -16 ÷ 2(-4)
x = 2
Answer C
Answer:
P < -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Add 4 to both sides.
Therefore, the answer is P < -1! (Also, the graphed solution is below.)
Answer:
2/8
Step-by-step explanation:
1. take 1/8 and multiply it by 2/1
Answer:
a. The price per ticket is 4 bucks, and b. you get 1/4 of a ticket for a dollar.
1. the penguin walks 75 feet in 45 seconds, and 2. it takes 27 seconds to walk 45 feet.
Step-by-step explanation:
Tickets:
16 dollars divided by 4 tickets is 4 dollars, so 4 dollars = 1 ticket. therefore, 1 dollar gives you 1/4 of a ticket.
Penguins
formula: X = feet, Y = seconds
X*0.6=Y
10 feet*0.6=6 seconds
(?) feet*0.6= 45 seconds
75 feet*0.6=45 seconds
same thing, but backwards this time
45 feet*0.6=(?) seconds
45 feet*0.6= 27 seconds
Hey can I have brainly please I am really close to leveling up
thx
I hope this helps you
x=4
f (4)=4+3
f (4)=7
x= -2
g (-2)=13. (-2)-5
g (-2)= -26-5
g (-2)= -31
f (4)+g (-2)= 7 -31= -24
