It would be the first table. As you can see there is a pattern, every hour the temperature increases by 6 degrees. Since this pattern is throughout the whole table that is the correct answer. You could also graph the points, time on the horizontal axis and temperature on the vertical axis, it will create a straight line. (That’s the best I could explain it). Also the second table would be exponential, which is not proportional...
Answer:
2.73 8.75
Step-by-step explanation:
n = 1
1 (DOUBLE) = 1+1 = 2
2 +3/4 = 1.5
1.5 +2 = 3.5
3.5 x 0.22 = 0.77
3.5 - 0.77 = 2.73
n = 1
1 + 3/4 = 1 + 0.75 = 1.75
1.75 (DOUBLE) = 3.5
3.5 x 2 1/2 = 8.75
Answer:
(4x-10)+62=180
Step-by-step explanation:
4x-72=180
4x=180+72
x=252/4
x=63°
Answer:
A
Step-by-step explanation:
X = y - 3
x + 3y = 13
x + 3y = 13 (replace x with y-3)
y - 3 + 3y = 13
4y - 3 = 13
4y = 13 + 3
4y = 16
y = 16/4
y = 4
x = y - 3
x = 4 - 3
x = 1
The answer is A. (1,4)
