Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
Answer:
a) -4/3
b) 8
c) -2/3
d) 2
Step-by-step explanation:
In all four cases replace the value of "x" in the function's expression, and evaluate to find the numerical answer:
a) ![f(\frac{1}{4}) = \frac{1}{\frac{1}{4}-1 } =\frac{1}{\frac{1}{4}-\frac{4}{4} }= \frac{1}{-\frac{3}{4} } = -\frac{4}{3}](https://tex.z-dn.net/?f=f%28%5Cfrac%7B1%7D%7B4%7D%29%20%3D%20%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B4%7D-1%20%7D%20%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B4%7D-%5Cfrac%7B4%7D%7B4%7D%20%20%7D%3D%20%5Cfrac%7B1%7D%7B-%5Cfrac%7B3%7D%7B4%7D%20%7D%20%3D%20-%5Cfrac%7B4%7D%7B3%7D)
b) ![g(\frac{1}{4} ) = \frac{1}{\frac{1}{4} } +4 = 4 + 4 = 8](https://tex.z-dn.net/?f=g%28%5Cfrac%7B1%7D%7B4%7D%20%29%20%3D%20%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%20%2B4%20%3D%204%20%2B%204%20%3D%208)
c) ![f(-\frac{1}{2}) = \frac{1}{-\frac{1}{2}-1 } =\frac{1}{-\frac{1}{2}-\frac{2}{2} }= \frac{1}{-\frac{3}{2} } = -\frac{2}{3}](https://tex.z-dn.net/?f=f%28-%5Cfrac%7B1%7D%7B2%7D%29%20%3D%20%5Cfrac%7B1%7D%7B-%5Cfrac%7B1%7D%7B2%7D-1%20%7D%20%3D%5Cfrac%7B1%7D%7B-%5Cfrac%7B1%7D%7B2%7D-%5Cfrac%7B2%7D%7B2%7D%20%20%7D%3D%20%5Cfrac%7B1%7D%7B-%5Cfrac%7B3%7D%7B2%7D%20%7D%20%3D%20-%5Cfrac%7B2%7D%7B3%7D)
d) ![g(-\frac{1}{2} ) = \frac{1}{-\frac{1}{2} } +4 = -2 + 4 = 2](https://tex.z-dn.net/?f=g%28-%5Cfrac%7B1%7D%7B2%7D%20%29%20%3D%20%5Cfrac%7B1%7D%7B-%5Cfrac%7B1%7D%7B2%7D%20%7D%20%2B4%20%3D%20-2%20%2B%204%20%3D%202)
