Answer:
1, 11x + 3y + 15z
2, 3x + 12y + -5z
Step-by-step explanation:
all you need to do is combined the like terms and make sure the signs (<em>positive and negative signs</em>) are right
Answer:I’m sorry this is hard I don’t think I have the right answer chose C
Step-by-step explanation:
![y = {x}^{3} - 4 {x}^{2} - 45x \\ y = x( {x}^{2} - 4x - 45) \\ y = x(x + 5)(x - 9) \\ x = 0, - 5,9](https://tex.z-dn.net/?f=y%20%3D%20%7Bx%7D%5E%7B3%7D%20%20-%204%20%7Bx%7D%5E%7B2%7D%20%20-%2045x%20%5C%5C%20y%20%3D%20x%28%20%7Bx%7D%5E%7B2%7D%20%20-%204x%20-%2045%29%20%5C%5C%20y%20%3D%20x%28x%20%2B%205%29%28x%20-%209%29%20%5C%5C%20x%20%3D%200%2C%20-%205%2C9)
So, to find our x-intercepts, y must be zero
![0 = x \\ \\ 0 = (x + 5) \\ - 5 = x \\ \\ 0 = (x - 9) \\ 9 = x](https://tex.z-dn.net/?f=0%20%3D%20x%20%5C%5C%20%20%5C%5C%200%20%3D%20%28x%20%2B%205%29%20%5C%5C%20%20-%205%20%3D%20x%20%5C%5C%20%20%5C%5C%200%20%3D%20%28x%20-%209%29%20%5C%5C%209%20%3D%20x)
ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts
Answer:
what?
Step-by-step explanation:
Answer:
3 miles
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles
This is the change in miles / change in time.
Chang in miles = 3
Change in time = 1
Slope = 3/1
Slope = 3
