It will take him 16 hours because 25 is 1/4 of 100% so 4 times 4 is 16. So 16 is your answer :)
Its true a. A linear system is a set of equations
Answer:
3.5 blocks.
Step-by-step explanation:
After walking 3.5 blocks back she is back at her starting point.
We know that
in a quadratic equation of the form
ax²+bx+c=0
the discriminant is
D=b²-4ac
if D> 0 <span>then there are two real number solutions
if D=0 </span><span>then there's only one real number solution.
if D< 0 </span><span>then there are two complex number solutions
in this problem
we have
</span>3x²<span>-6x+3=0
a=3
b=-6
c=3
so
</span>D=b²-4ac-----> D=(-6)²-4*(3*3)----->D=36-36------->D=0
therefore
there's only one real number solution
