First you need to substitute x for -2 and y for 3 in the equation.
So it would be...
6(-2) + 5 - 3(3)
-12+5-9
Then your answer is -16.
Hope that helped!
Answer:
1: (4,1) x=4 y=1
2: (1,10) x=1 y=10
3: (-25/4,5) x= -25/4 y=5
Step-by-step explanation:
It would be a lot to explain all three so if you really need it just ask
Answer:
$ 3820
Step-by-step explanation:
When the car is new, it is 0 year old. It means, t = 0
Initial value = 26,000 (0.84)^0 = 26,000(1)
Initial value = $ 26000
Similarly, when car is 11 year old, t = 11
=> 26000(0.84)¹¹ = 26000(0.14691)
≈ $ 3819.842
≈ $ 3820 (round to near ten)
First move the 2n over to the other side by subtracting it
so
4n=-8
then divide 4n by 4 and do the same to the other side
so
n= -8/4
n= -2
y = 4
first note that the right side simplifies to 12, equation can be written
= 12 ( multiply both sides by 0.8 )
2y + 1.6 = 9.6 ( subtract 1.6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
