Answer:14
Step-by-step explanation:
x + 7 = 21
group like terms
x = 21 - 7
When positive cross = sign it turns negative
x = 14
We plot these data where x corresponds to the time and y corresponds to the velocity. Using the calculator, y - intercept is equal to 50. y-intercept is the y-value when x is zero. The car is accelerating. The average rate of change when x =1 to x=3 is (56-52)/(3-1) or 2 miles/hour^2. The car would reach 60 miles/hour when x=5 from the acceleration of 2. Domain is 5.
-2x+12 because you gotta distribute your -2 to the rest of the equation.
