Answer: 82
Step-by-step explanation:
(N + 1 )^ 2 for N = -9
(-9 +1))^ 2
81+1
82
(-9 +1))^ 2 - Every number raised to power 2 positive your result will be positive
11/12 hours left. 1 2/3 - 3/4 = 11/12. First, find the common denominator (12) . The problem is now 1 8/12 - 9/12. Use the 1 in (1 8/12) to borrow. Multiply the denominator by 1 (12) and add that to the numerator. The question is now 20/12 - 9/12. I assume that you can finish it off from there.
Answer: It takes 1/3 of a minute for each lap
Step-by-step explanation:
We can use elimination to solve the system:
x+2y=0 Multiply the first equation by negative 2 so we can eliminate
2x+4y=0
-2-4y=0 Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0
0=0
Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.
you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.
