All positive integers less than or equal to 72<span />
Step-by-step explanation:
x^2 -2kx +7k -12 = 0
two equal roots -->Δ = b^2 -4ac = 4k^2 - 4(7k-12)=0 = 4(k^2 - 7k +12)=4(k-4)(k-3)=0
so k =3 and k =4
A) 26 minus x
b)8 times x
c)760 minus x
d)2.79 divided by x
The smallest amount of points at which they could intersect is 2.
