Aregular lightbulb uses 20 watts less then twice the power of an energy-saver lightbulb. if the regular bulb uses 170 watts, how much does the energy-saver bulb use?

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

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.
