She ran 21 inches. Thats your answer. sorry if im wrong
You can figure the line for each pair of points, or you can try the points in the equation you have and see which are on the line.
First answer: x=1, y=-5×1 +4 = -1 . . . not 9. (1, 9) is not a point on the line
Second answer: x=2, y=-5×2 +4 = -6 . . . not -14. (2, 14) is not a point on the line
Third answer: (see the calculation for the first answer) . . . -1 ≠ 1. (1, 1) is not a point on the line
Fourth answer: (see the calculation for the second answer) We know that (2, -6) is on the given line. Checking (4, -16), we find it is as well.
The appropriate choice is the 4th answer:
... a line passing through the points (2, -6) and (4, -16)
Answer:
division i think srry if im wrong
Step-by-step explanation:
Answer: x^2+8x+16
Step-by-step explanation:
Following (a+b)^2=a^2+2ab+b^2,
(x+4)^2=x^2+2(4x)+(4)^2
x^2+8x+16
