Answer:
x=4, y=9
Step-by-step explanation:
Solve with substitution.
We have that
<span>6x^2 +12x+5=0
to find the x intercepts resolve the second order equation
x=[-b(+-)</span>√(b²-4ac)]/2a
x1=[-12(+)√(12²-4*6*5)]/12---> [-12(+)√(144-120)]/12
=[-12(+)√(24)]/12--------> -1+√24/12-----> -1+√6/6
x1=-1+√6/6
so
x2=-1-√6/6
see the graph in the attached figure
<span>
the answer is
</span>the x-intercepts for the graph of the quadratic function in <span>exact form are
</span>x1=-1+√6/6
x2=-1-√6/6

Total children = 24
Probability of 2 black haired = 2/ 8 = 1/4
Answer:B is similar
Step-by-step explanation:
Do you know triangles add up to 180°
So...
180-(90+58)= 32°
