I got the answer b hope it helps
Step-by-step explanation:
Answer:
We choose B. (1, 10)
Step-by-step explanation:
Given the exponential model in the form y = a
- passes through the points (2, 50)
<=> 50 = a
<=> a = (1)
- passes through the points (3, 250)
<=> 250 = a (2)
Substitute (1) into (2) we have:
250 =
<=> 50b = 250
<=> b = 5
=> a = = 2
Hence, our exponential model is: y =2*
Let analyse all possible answer:
A. (0, 5) we have: y =2* ≠ 5 so it is wrong
B. (1, 10) we have: y = 2* so it is true
C. (4, 450) we have: y = 2* ≠ 450 so it is wrong
D. (5, 650) we have: y = 2* ≠ 650 so it is wrong
Hence we choose B. (1, 10)
If your sum of all of them added up is 180, then all you will do is add 61+79 that will give you 140 and then subtract that from 180. Your answer should be 40 degrees. :) hope this helps
Answer:
B,C&F
Step-by-step explanation:
-2x>-4
multiplied by -1 gives 2x<4
And you devide both sides by 2 you get x<2
The numbers smaller than 2 in your options are 1,1.5 and -2
