Options 1 does not represent a function
Answer:
x = 1 and x = -1
Step-by-step explanation:
Next time, please separate the equations with a comma or semicolon. Thanks.
We can substitute 4x for y in the quadratic equation x^2 + y^2=17:
x² + (4x)²=17.
Then x² + 16x² = 17, or
17x² = 17, or x² = 1. There are two solutions: x = 1 and x = -1.
Answer:
Step-by-step explanation:
x=o . so the line is parallel to x-axis.
So the line parallel to the line : x = 0
As the perpendicular line will be parallel to y-axis. so the slope of the line parallel to y-axis is undefined.
2 x 2 x 5 x 5 x 5
2^2 x 5^3
