kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer:
X=7 1/3, y=0
Step-by-step explanation:
1) 1.5x+2y=11 --> 3x+4y=22
2) 3x+6y=22
Subtract 1) from 2)
2y=0
y=0
Plug into 2)
3x+6*0=22
3x=22
x=7 1/3
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:
x = 4 + sqrt(5) or x = 4 - sqrt(5)
Step-by-step explanation:
Solve for x:
(x - 4)^2 = 5
Take the square root of both sides:
x - 4 = sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
x = 4 + sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
Answer: x = 4 + sqrt(5) or x = 4 - sqrt(5)
