Answer:
X=15
y=17
Step-by-step explanation:
4y+112=180
4y=180-112
4y=68
y=68/4
y=17
7x+7=112
7x=112-7
7x=105
X=105/7
X=15
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
Answer:
-4
Step-by-step explanation:
5-2=3
3/3=1
1-5= -4
If the point is on the unit circle:
x² + (√3/3 )² = 1²
x² + 3/9 = 1
x² + 1/3 = 1
x² = 1 - 1/3
x² = 2/3 / √
x = √2/√3 · √3/√3 = √6 / 3
Answer: A ) square root (6) / 3
