D. Because you're multiplying 3 by a number which is what the variable represents (n), then you're just adding 7 to that which equals 19 all together. It all translates to 3n+7=19.
The Y-intercept is the point at which the graph intersects the y-axis
Enjoy the rest of you're night!!!!
We know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm
the answer is
285.9 cm
6 goes into 31 5 times which is 30 so the answer would be 5 1/6
(3x - 1) + 5
Hope this helps!
