Given the replacement values x=-3/2 and 17/6 evaluate (a) xy and (b) x÷y

(a) xy

(-3/2) • (17/6)

-51/12

(b) x ÷ y

(-3/2) ÷ (17/6)

(-3/2) • (6/17)

-18/34

-8/17

A)

B) 0.50

C) y=15

Step-by-step explanation:

Let x be the number of miles traveled by car.

Then according to the problem the function is linear function (y=mx+c )as the rate of change is constant i.e. m= $0.50 per mile, the cost function (y in dollars) is given by

The graph of this equation will form a straight line .

The slope of the line is the rate of change of the function i.e. $0.50 per mile .

Hence, the slope (m)= 0.50

The y intercept occurs when x=0, so put x=0 in the equation we get y=15
