Answer:
The axis of symmetry is -b/2a
The x-intercept shown is 3 units away from the axis of symmetry.
The other x-intercept also must be 3 units away from the axis of symmetry but on the opposite side.
Subtract 3 from the axis of symmetry.
The other x-intercept is (-b/2a-3,0)
Step-by-step explanation:
Keywords
parallel, perpendicular, graphing, linear equation, slope, lines
we know that
If two <u>lines</u> are <u>perpendicular</u>, then the product of their <u>slope</u> is equal to minus one
so
![m1*m2=-1](https://tex.z-dn.net/?f=m1%2Am2%3D-1)
If two <u>lines</u> are <u>parallel</u>, then their <u>slope</u> are equal
![m1=m2](https://tex.z-dn.net/?f=m1%3Dm2)
In this problem we have
--------> <u>linear equation</u> A
the <u>slope</u> is ![m1=1](https://tex.z-dn.net/?f=m1%3D1)
--------> <u>linear equation</u> B
the <u>slope</u> is ![m2=-1](https://tex.z-dn.net/?f=m2%3D-1)
Find the product
---------> the <u>lines</u> are <u>perpendicular</u>
therefore
the answer is the option B
Perpendicular
using a<u> graphing</u> tool
see the attached figure
<span>Equation:
water - water = water
0.72*60 - x = 0.68(60-x)
72*60 - 100x = 68*60 - 68x
-32x = -4*60
x = (1/8)60
x = 7.5 liters (amt of water to evaporate)</span>
