There is not a real way to justify this, but I saw first that 400-80 equals 320 which is double 160. This made me think that the period of time during this was 2 hours. The car drove 80 miles in two hours and the plane flew 400 miles in 2 hours. The period for one hour would be 40 mph for the car and 200 mph for the plane. 200-40=160. I have no idea how to prove it though and I’m hoping you can go backwards.
I'm pretty sure the answer is G. I'm not 100% sure tho. Hope this helps! :)
Answer:
2/7 , 7/13 ,5/9,10/11
Step-by-step explanation:
5/9 , 7/13 , 2/7, and 10/11
5/9 = 0.555
7/13≅ 0.54
2/7 ≅0.29
10/11=0.90
ascending order means from least to greatest:
2/7 , 7/13 ,5/9,10/11
Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
A set of ordered pairs that has each value of the x-coordinate only once is a function.
