Im thinking it's the first one, I'm not sure though, I know g(x) is the y axis so (1/2)x correct me if I'm wrong
Let the distance of the race be d miles. We can now write the equation:

which when solved, gives the value of as 4.2 miles.
The time to walk 4.2 miles at 3 mph is 4.2/3 = 1.4 hours.
The answer is 1.4 hours or 1 hour 24 minutes.
45 - 15 - 15 = 45 - 30
45 - 30 = (15)
Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
