3x^2 + 6x - 24
3(x^2 + 2x - 8)
3(x + 4)(x - 2) <==
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.
Answers my vary but what i got is 140 divided by 10 = 14
Answer:
-2(2x+4)
Step-by-step explanation:
The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
