Answer:
No. There are two solutions to the point x=-2: 9 and 5.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, for the same x position, then the graph is not a function.

Answer:
2.Ellipse
Step-by-step explanation:
The given equation represents an ellipse.
Standard form of ellipse is given as:
![\frac{x^2}{a^2} +\frac{y^2}{b^2} = 1\\\\\implies \frac{x^2}{16} - \frac{y^2}{4} = 1\\](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E2%7D%7Ba%5E2%7D%20%2B%5Cfrac%7By%5E2%7D%7Bb%5E2%7D%20%3D%201%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Cimplies%20%5Cfrac%7Bx%5E2%7D%7B16%7D%20-%20%5Cfrac%7By%5E2%7D%7B4%7D%20%3D%201%5C%5C)
Answer:
b.
b.
Step-by-step explanation:
scientific notation should have one positive in front of the decimal point, then any number (>=1) of positions after the decimal point, followed by the multiplication with the property power of 10.
the only number not following that rule is b (2 positions in front of the decimal point).
4x - 2y = 6
2x - y = 3
are the same line, as we can multiply the second equation by 2 and get exactly equation 1.
so, both lines have the same slope and the same y-intercept. therefore, they have infinitely many solutions.
