Answer:
B
Step-by-step explanation:
They both scored the same so no one it was even .
Answer:
The x-coordinate of A is:
a = 6.1
Step-by-step explanation:
For point A:
x-coordinate = a
x-coordinate + y-coordinate = 14
y-coordinate = 14 - x-coordinate
y-coordinate = 14 - a
So point A can be written as (a, 14-a)
Let (a,14) be (x₁,y₁)
Point P can be written as (3a, a²+13a-11)
Let P be (x₂,y₂)
Slope of a line passing through 2 point is given as:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
where m=7
Substitute all values
![7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1](https://tex.z-dn.net/?f=7%3D%5Cfrac%7B%28a%5E2%2B13a-11%29-%2814-a%29%7D%7B3a-a%7D%5C%5C7%3D%5Cfrac%7Ba%5E2%2B13a-a-11-14%7D%7B3a-a%7D%5C%5C7%3D%5Cfrac%7Ba%5E2%2B12a-25%7D%7B2a%7D%5C%5C14a%3Da%5E2%2B12a-25%5C%5Ca%5E2-2a-25%3D0%5C%5Ca%3D6.1%2Ca%3D-4.1)
As A has only positive coordinates
a = 6.1
Answer:
Ahimsa, it means 'non-injury' and 'non-killing'
Answer:
Two double roots in this case.
I could say 4, but you have a pair of double roots x = 6 and x = -2
Step-by-step explanation:
x = 6 is a double root of f(x)
x = -2 is a double root of f(x)
