Answer:
(11.4 - 22.8) / (26 - 7)
-11.4 / 19 this is the rate at which it burns - the slope
h = (-11.4/19)t + b
22.8 = (-11.4/19)7 + b
22.8 = (-79.8/19) + b
22.8 = -4.2 + b
27 = b
h = (-11.4/19)t + 27
Substitute 15 for t to determine the height of the candle.
7(N) + 5 It's 7 times a number first, then add 5
Answer:
B
Step-by-step explanation:
To evaluate g(7) substitute x = 7 into g(x) , that is
g(7) =
× 7 - 
=
- 
=
→ B
-converting to a common denominator
The terms -c of the left side was converted to -4ac/4a to have the same denominator of b^2/4a.
