Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
There is no diagram, so you should guess C. C is the most likely to be chosen as an answer.
Since all sides of a cube are equal...,
Let one side length of a cube be (z)
;Volume = z × z × z
;Volume = z^3
; 27 = z^3....where we then say that..,
; z(side length) = cube root of (27)
; Hence..., Side Length = 3 yards
Answer:
(3,6)
Step-by-step explanation:
-2x+3y=12
Let x = 3
-2(3) +3y = 12
-6+3y = 12
Add 6 to each side
-6+6 +3y = 12+6
3y = 18
Divide each side by 3
3y/3 = 18/3
y = 6
