dexar [7]2 years ago
6 0

Answer:

equation= y-y¹=m(x-x¹)

where m = gradient or slope

slope= <u>y²</u><u>-</u><u>y</u><u>¹</u>

x²-x¹

= <u>4--</u><u>7</u>

-1--3

= <u>4+7</u>

-1+3

= <u>1</u><u>1</u>

2

= 5.5

equation= y-4=5.5(x--1)

= y-4=5.5(x+1)

y-4= 5.5x+5.5

y= 5.5x+5.5+4

y= 5.5x+9.5

qaws [65]

Answer:

  $25000

Step-by-step explanation:

If the salvage value is 20% of the cost, then 80% of the cost will be depreciated over 10 years. Over the 5 years from Jan 1 20X1 to Dec 31 20X5, the $10,000 accumulated depreciation represents 5/10 of that 80%, or 40% of the initial cost.

  $10,000 = 0.40 × cost

  $10,000/0.40 = cost = $25,000

The acquisition cost of the equipment was $25,000.

GarryVolchara [31]

Answer:

The answer is y= -1/3x-5

Step-by-step explanation:

(9, -8) and (-6, -3)

m= y²-y¹/x²-x1

m= (-3)-(-8)/(-6)-9

m= 5/-15

m=-1/3

y=mx+b

y=-1/3x+b

-3=-1/3(-6)+b

-3=2+b

-2 -2

-5=b

The answer is y=-1/3x-5
