Answer:
x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3
Step-by-step explanation:
Subtract 15 from both sides
8x=-15
Divide 8 on both sides
Now you get your answer
x=-15/8 or -1 7/15
OR
Combine like terms
9x+15=0
Subtract 15 from both sides
9x=-15
Divide 9 from both sides
x=-15/9
Simplify
x=-5/3 or -1 2/3
Answer:
two solutions : (0,-3) , (3,0)
Step-by-step explanation:
hello :
y= x² -2x -3 ...(*)
y= x -3....(**)
x²-2x-3 = x -3
x²-3x=0
x(x-3) = 0
x=0 or x-3=0
x=0 or x=3
but : y=x-3
1) x=0 y=0-3=-3
2) x=3 y=3-3=0
two solutions : (0,-3) , (3,0)
Answer:
x<-4 or x≤4
Step-by-step explanation:
Answer: a= -5
Step by step: 2a - 2 = 6a + 18
-2a -2a
-2 = 4 a + 18
-18 - 18
-20 = 4 a
-5 = a
Answer:
1721 $
1612.80
Step-by-step explanation:
Straight line depreciation means depreciation is the same spread over for all the years. The spread over amount is nothing but total cost of equipment - salvage value.
Here we have
Cost of equipment(Purchase cost) ... 18000
Shipping costs ... 620
Installation costs ... 590
Total cost of equipment ... 19210
Less: salvage value at the end ... 2000
Net cost of equipment for 10 years ... 17210
Depreciation per year = Net cost /number of years of life
= 17210/10 = 1721/-
Hence answer is 1721/- for all years and also hence for year 2.

Peach tree has an average life of 12 years. First 3 years no benefit would arise, 4 to 8 would be peak and after that slowly decreasing.
Hence in 9th year there would be least value and least depreciation.
Hence answer is $1612.80
