16 - (-15) = 16 + 15 = 31...difference of 31 degrees
Answer:
x = 9
Step-by-step explanation:
-2x + 3 = -15
-2x = -18
x = 9
It would be bigger than 1/2 inches because they are simply asking for the difference which is 5 1/2-5= 1/2.
3/5 x 30 days = 18 days were sunny.
Answer:
y = 2 * 9 ^ x
Step-by-step explanation:
From the first point, you can get the value of a, since any number with power 0 with always equal to 1
Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.
- 1458 = 2b ^ 3
- 729 = b ^ 3
- B = 9
