Answer:
hich graph represents this system?
y = 2 x + 1. y = negative 4 x + 7.
On a coordinate plane, a line goes through (0, 7) and (1, 3) and another goes through (1, 3) and (2, 5).
On a coordinate plane, a line goes through (negative 4, 0) and (0, 7) and another line goes through (negative 4, 3) and (0, 1).
On a coordinate plane, a line goes through (0, negative 4) and (1, 3) and another goes through (0, 2) and (1, 3).
On a coordinate plane, a line goes through (0, 7) and (8, 5) and another line goes through (0, 1) and (8, 5).

Sending all passengers below while refueling
Explanation:
Safety tips for refueling a boat includes;
1) People that are not involved in the refueling of the boat should be made to leave the area
2) The engines, electronics, ignition system and open flames should be off
3) Ensure the boat is properly secured to the dock
4) Do not use the hands-free clips and try not to be distracted
5) Ensure not to completely fill the fuel tank as fuel has the tendency to expand as its temperature rises. The tank should have about 90% filling
The suns gravity pulls on the planets and keeps them in place. Its gravitational pull puts them in orbit around the sun
Answer:
Velocity after collision will be 20 m/sec
Explanation:
We have given mass of arrow 
Mass of arrow 
Mass of apple 
Apple is at rest so velocity of apple 
According to conservation of momentum
Momentum before collision is equal to momentum after collision
v = 20 m/sec
Answer:
cos to = $ 24
Explanation:
When replacing the bulb only 25% of the energy is used, therefore
W = 0.25 100
W = 25 W
Let's look for the energy in the life of the bulb
E = 25 10⁻³ 12000
E = 300 Kwh
now we can calculate the cost using a direct proportion rule.
Cost = 0.08 300
cos to = $ 24
