Answer: 32 light colors
Step-by-step explanation:
5 : 8 = 20 : ?
20/5 = 4
8(4) = 32
A = y(9 + 3x) factor y out of 9y+3yx, then devided both sides by (9+3x)
A/(9+3x) = y
We can deduce that the graph is a negative parabola from
-0.002x^2. Therefore, the graph is increasing < 1250 and decreasing > 1250.
P(x) is increasing from
and decreasing from
![(1250,\infty]](https://tex.z-dn.net/?f=%281250%2C%5Cinfty%5D)
.
Answer:
-5
Step-by-step explanation:
From your knowledge of multiplication tables, you know that ...
-35 = -(7×5) = 7×(-5)
Then comparing to the given equation, you realize ...
t = -5
_____
Or, you can recognize 7 as the coefficient of t and divide both sides of the equation by that:
-35/7 = (7t)/7
-5 = t
