Answer:
He is right
Step-by-step explanation:

Hope this helps!
The root (zero) of this problem is A., x =5 only.
Substitute f(x)=0
0=x^2 - 10x + 25
Solve for x.
x = 5.
Okay, here we have this:
Considering the provided information and that a positive correlation refers to the fact that as one increases the other also increases, we obtain that:
As more calories are eaten, it influences that the weight also increases, it means that there is a positive correlation.
The nearest tenth is 3.8 or 3.80
Answer:
y - 7 = (x + 5)
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Slope(m) = 1
Point: (-5, 7) = (x1, y1)
To write the equation in point-slope form, we need to know the slope and one point. Since we were already given the values of the slope and one point, all we have to do is input those values into the equation:
y - y1 = m(x - x1)
y - 7 = 1(x - (-5))
y - 7 = (x + 5)
The equation in point-slope form is: y - 7 = (x + 5)
