1 day equals 24 hours.
18 hours / 24 hours = 0.75 days
The total days is 5.75 days.
Multiply the amount the bulb uses in 1 day by 5.75 days:
3600 x 5.75 = 20,700 watt-hours.
Answer:
{5,6,7}
Step-by-step explanation:
3s>12
divide by 3 on both sides and you get
s>4
so {5,6,7} is the only one that works since it needs to be greater than 4
sorry if I replied too late, but I hope this helps
It is y+1=0.9(x+4) because the formula is y - y1=m(x + x1) you only need one point and the slope. If you have two points, you need to find the slope by using the slope formula slope=y2-y1/x2-x1. Filling it in it would look like slope=7-(-1)/5-(-4). The double negatives cancel each other out and it turns to addition signs leaving us with slope=7+1/5+4 so the slope is 8/9 or 0.9. Now you can fill out the point-slope formula y+1=0.9(x+4)
