Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
Answer:
You can factor it by taking out the five, since it is a common factor of 5 and 15 (for example: 5(-x - 3) ), you can remove the negative value ( -1(5x+15) ), or your can remove the negative and the 5 (-5(x+3) ).
Step-by-step explanation:
Answer:
y = 3x² - 15x + 18
Step-by-step explanation:
y = 3(x - 3)(x - 2) ← expand factors using FOIL
= 3(x² - 5x + 6) ← distribute parenthesis by 3
y = 3x² - 15x + 18 ← in standard form

Answer:
B (although you failed to put the division bar between the 24 and the 5)
Step-by-step explanation:
The x-intercept exists where y = 0. So we plug in 0 for y and solve for x:
-5x + 3(0) = -24 and
-5x = -24 so
x = 24/5
The y-intercept exists where x = 0. So we plug in 0 for x and solve for y:
-5(0) + 3y = -24 and
3y = -24 so
y = -8
The coordinate for the x-intercept is (24/5, 0)
The coordinate or the y-intercept is (0, -8)
Choice B
