For this case what you can do is factorize the <span>polynomial equation</span>, which would be left like follows
x ^ 3 + x ^ 2 + 9x + 9 = 0
(x + 1) (x ^ 2 + 9) = 0
Resolving, we have that the missing root is
x = -1
Answer
x=-1
Well to find the area of any figure you must first have knowledge on the formula. The formula for a triangle is 1/2 x b x h. Since you have the base 32, multiply that by 1/2 which will give you 16. Then you have to multiply 16 by the height. I'm not sure what the height is because you never gave me one but hopefully this helped! God bless :)
The cost per unit of the auto shop function is the slope of the function
87 represents the slope and the cost per tire purchased
The function is given as:
![\mathbf{C(t) = 87t + 32}](https://tex.z-dn.net/?f=%5Cmathbf%7BC%28t%29%20%3D%2087t%20%2B%2032%7D)
A linear function is represented as:
![\mathbf{C(t) = mt + b}](https://tex.z-dn.net/?f=%5Cmathbf%7BC%28t%29%20%3D%20mt%20%2B%20b%7D)
Where:
m represents the slope or the unit rate.
So, by comparison:
![\mathbf{m = 87}](https://tex.z-dn.net/?f=%5Cmathbf%7Bm%20%3D%2087%7D)
This means that 87 represents the slope and the cost per tire purchased

Answer:
a. y = (3/5)× x +1
Step-by-step explanation:
y= mx+c
m = (13-4)/(20-5) = 9/15 = 3/5
c= 1
so, y= mx+c becomes y= (3/5) × x +1
