8. Last year Carlito Olmstead drove 142,400 miles in the delivery van that he purchased 2 years ago for $22,565.00. It is now worth $10,320.00. HS variable costs this year were gasoline $28,365.21, oil and filters $598.10 2 sets of tires $897.60, battery $85.95, and maintenance $1,256.54. His insurance cost $2,884.26, registration was $159.65, and loan interest we $658.93. What was the cost per mile for an to operate his van?​

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
