Step-by-step explanation:
Let x be the number.
Then the algebraic expression will be x^2 + 11x.
If f(x)=x^2+7x+20 has the same roots as g(x)=Ax^2+Bx+1, then
one must be a multiple of the other.
By comparison of the constant terms, we know that 20g(x)=f(x), or
g(x)=(1/20)f(x)
=(1/20)(x^2+7x+20)
=(1/20)x^2 + (7/20)x + 20/20
=(1/20)x^2 + (7/20)x + 1
Therefore A=(1/20), B=(7/20), and A+B=(1+7)/20=8/20=2/5
Answer:
y-1=3(x-2)
Step-by-step explanation:
Known:
Point slope form is this: y-y₁=m(x-x₁)
(2,1)
2=x1
1=y1
3=m
y-1=3(x-2)
