(a) -7

(b) 7

(c) DNE

Step-by-step explanation:

(a) lim f(x) x -->0-

= lim 7 (-x) / x

= -7

(b)  lim f(x) x -->0+

= lim 7y / y

= 7

(c) lim f(x) ≠ lim f(x)

≠: does not equal sign

x -->0-  ≠ x -->0+

so lim f(x) x -->0 = does not exist

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the answer would be 44.79
