Answer:
Step-by-step explanation:
hello :
(x² - 10x) + (y² - 2y) + 15 = 0
(x² - 10x+25-25) + (y² - 2y+1-1) + 15 = 0
(x² - 10x+25)-25 + (y² - 2y+1)-1 + 15 = 0
(x-5)²+(y-1)² = 11
the center is (5;1) and radius √11
That one i believe would be A
Answer:
2
Step-by-step explanation:
basically logarithms are like reverse exponents
log7, 49 is basically asking 7 to the what gets you 49
because of that its 2 because 7^2 gets you 49
These would be 2 of the 4 equations, because 6 times 9 equals 54 and 9 times 6 equals 54, but are written in a different way. Thus meaning they are 2 of the 4 equations.
These 2 would be the final to, because 54 divided by 6 is 9, and 54 divided by 9 is 6. Thus meaning they are the final 2 equations.
I hope this helps!
