Answer:
(attached file #2)
Step-by-step explanation:
let's change the variable n to a variable x (it can be x and y):
x ≥ -8
go to the X-axis which is the line going horizontal, just as the first picture attached!
2. Now go to the -8 on that line and draw a straight bold line going up (vertical)
and there you have the answer to the question.
if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!
Hope this helps,
Lucas
Answer:
H = h + x
h = 568 meters
Step-by-step explanation:
The helicopter descends 114 meters to be 454 meters above the ground.
Therefore, the equation which describes this situation using h as the original height will be given by
H = h + x ....... (1)
Where H is the final height from the ground and x is the height that the helicopter ascends(Positive sign) or descends(Negative sign). (Answer)
Here, in our case, H = 454 meters and x = -114 meters.
Therefore, the original height of the helicopter from ground will be
h = H - x = 454 - (-114) = 568 meters. (Answer)

Step-by-step explanation:
step 1. (((0-(4•(a2)))+3ab)+(12•(b2)))+(((9•(a2))+ab)-7b2)
step 2. (((0-(4•(a2)))+3ab)+(12•(b2)))+((32a2+ab)-7b2)
step 3.(((0-(4•(a2)))+3ab)+(22•3b2))+(9a2+ab-7b2)
step 4. (((0-(4•(a2)))+3ab)+(22•3b2))+(9a2+ab-7b2)
step 5. 5.1 Factoring 5a2 + 4ab + 5b2
Answer:
apples= 15
oranges = 12
Step-by-step explanation:
5+4=9
27/9=3
therefore
apples=3*5=15
oranges=4*3=12
