Answer:
y = - 400 + 700x
Step-by-step explanation:
Nour's altitude increased at a constant rate from the Dead Sea up to Amman.
Initially, her altitude was 400 meters below from the sea level and then she arrived at an altitude was 1000 meters above sea level arrived to Amman, 2 hours later.
So, she moves (400 + 1000) = 1400 meters in 2 hours.
Therefore, her rate of change of altitude is
meters per hour.
Therefore, if y represents Nour's altitude in meters relative to the sea level after x hours then the relationship between the altitude and number of hours is given by
y = - 400 + 700x (Answer)
She will need 5 and a half hours. First step is to do 360-112.5 the pgs she read and her goal. then you'll get 247.5. To find how many hours you need to find the unit rate. so 247.5 divided by 45 is 5.5 hours.
hope this helped. can u mark me as the brainiest answer
Answer:
True
Step-by-step explanation:
4. 0.2618
5. 1.222
6. 5.236
Y=mx+b
subbing in m=-34
y=-34x+b
subbing in x=8 and y=-9
-9=(-34)(8)+b
solve for b:
b= 263
therefore, the equation of the line is
y=-34x+263
