Robin records the height of her plant for three months. If the pattern continues, what algebraic expression can Robin use to find the plant's height for any month? What will be the plants height at 12 months?
Month
Height
Incorrect Work/Solution
n= month
n+ 4 *plant height for any month
=12 + 4
=16
Identify and Explain the Error
The expression is n+ 4. The plant will be
16 inches tall at 12 months.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

m∠a is 90°

m∠b is 40°

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun

sure thing bud

hope this
