Answer:
2401
Step-by-step explanation:
7*7*7*7=2401
To determine the effect of the radius changes to the coefficients, we need to rewrite the form of the equation into:
(x−α)²+(y−β)²=r²
From the equation, we will see that:
C=−α∗2
D=−β∗2
and α²+β²−r²=E
where r represents the radius of the circle and α,βare the coordinate of the center of the circle.
Therefore, when the r decreases the coefficients C and D do not change but E increases.

Answer:
parallel lines
Step-by-step explanation:
the slope is 0
Answer: It is B and C.
Step-by-step explanation:
If you divde the -4 and -5 for choice B, it will become 4/5 since it's an absolute value.
For Choice C, it's also the same but before the fractions were negative and there is a negative sign which means it's also the aboslute value which is 4/5.
