Use the table of data from an investigation to answer the question
MASS OF BALL TIME TO HIT GROUND
10 1.02
15 1.01
26 1.62
A student is investigating gravity and falling objects. She drops three balls and times how long it takes each ball to hit the ground. What is the most likely source of error
A. She did not measure the circumference of the balls
B. She did not measure the mass after the balls hit the ground
C. She dropped the balls from diffrent heights
D. She uses balls that are different sizes
C. She dropped the balls from different heights
Which ordered pair is a solution of the equation y = –7x + 2? (1 point)
A (1, 2)
B (8, –54)
C ( 5, -35)
D (1, –7)
C (5, -35)
5 +m= 10
m = 5
x3+y3+z3=k
This equation represents a cubic equation in three variables. Without any additional information, it is impossible to determine the ordered pair that would satisfy this equation.

10 Hard Math Problems That May Never Be Solved
Today's mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It's one of the seven Millennium Prize Problems, with $1 million reward for its solution
The Riemann Hypothesis is considered one of the hardest math problems and is currently unsolved.
Which equation is an identity? (1 point)
A 11 – (2v + 3) = –2v – 8
B 5w + 8 – w = 6w – 2(w – 4)
C 7m – 2 = 8m + 4 – m
D 8y + 9 = 8y – 3
