What is the value of the expression below when w=3?
10w2 +9w-2

85 if the "2" in 10w(2) is being multiplied.

But if not, then

115 if the "2" in 10w2 is an exponent.

85

Step-by-step explanation:

10(3)2 + 9(3)-2

(30)2 + (27)-2

60+25=85

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
