Answer:
(-4,4)
Step-by-step explanation:
-5x-10y=-20
10x+10y=0
divide both sides by 2
-5x-10y=-20
5x+5y=0
that makes
-5y=-20
divide both sides by -5
y=4
now substitute 4 for y
10x+10 x 4=0
multiply
10x+40=0
subtract
10x=-40
divide
x=-4
You would take 25.5 feet and convert it to inches (306 inches) then just divide that by 6 and you get 51 inches or 4 feet 3 inches depending on how the answer needs to be reported.
Think it this way. 120/3=40. you need three consecutive numbers, which means those numbers are n1+n2+n3=120 and middle number n2 is gotten by dividing the number 120 with how many numbers you sum, in this case 3. the smaller number n1 is n2-1 and bigger n3 is n2+1
n1=40-1
n2=40+0
n3=40+1
Answer:
I don't actually know the answer you can ask the tutor
√-16 = 4i
So:-
3 ^√-16 = 3^4i
