19. Some drivers try to estimate their annual cost of repairs $c in relation to their average speed of driving s km/h using the equation
c=6s + 50. Draw the graph for 0 <s<160. From the graph find:
a) the estimated repair bill for a man who drives at an average
speed of 65 km/h
b) the average speed at which a motorist drives if his annual
repair bill is $300
c) the annual saving for a man who, on returning from a holiday,
reduces his average speed of driving from 100 km/h to 65 km/h.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

where is the picture

step-by-step explanation:

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
