Answer:
its y=-5x
Step-by-step explanation:
Why?
linear functions have only the slope, they dont include the y-intercept
Answer:

they are the same shape, but in different positions. hope that helps.
Which TWO expressions are equivalent to<em> </em><em>(x - y) </em>2/3 - 3/4 <em>(y-x)</em>
Answer:
C) To square a number, multiply the number by itself.
Step-by-step explanation:
A) is incorrect because square roots are made by multiplying the number to itself.
2 × 2 is the same as 2²
3 × 3 is the same as 3²
4 × 4 is the same as 4²
2² = 4
3² = 9
4² = 16
B) is incorrect because the inverse of squaring is finding the square root.
2² inverse is √4
3² inverse is √9
4² inverse is √16
D) is incorrect because perfect squares can be odd or even
A perfect square is a number made by squaring a whole number.
4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
Example:
This suggests two solutions,
and
.
However, upon plugging these solutions back into the equation, you get
which checks out, but
does not because
is defined only for
(assuming you're looking for real solutions only). So, we call
an extraneous solution, and the complete solution set (over the real numbers) is
.
