Answer:
3x + 11
Step-by-step explanation:
Remember BPEMDAS.
"Three times a number" is saying multiply 3 times a variable; in this case, <em>x</em>. So we have 3x
"The sun of 3x and 11" is saying add our 3x and 11, so: 3x + 11
The answer is A. To understand that, you need to put it in order by the x's and the y's to get x^2-6x + y^2-16y = -48. Now complete the square on both the x and the y terms to get (x^2-6x+9) +(y^2-16y+64) = -48+9+64. Rewriting that in vertex form on the left and doing the math on the right gives you
(x-3)^2 + (y-8)^2 = 25, which shows you a center of (3,8) and a radius of 5.
The answer to this question is 25
Answer:
Y=-2/5x
Step-by-step explanation:
Y-int: (0,0)
x-int:(-2,5)
Since they are the same, any change made to 1 will be the same in the other, resulting in infinite solutions.
