Show how to solve the problem 378 times 6 using place value with regrouping. explain how you knew when to regroup

2268

Step-by-step explanation:

We have to solve the problem 378 dimes 6 using place value.

Place of 8 in 378 = once

Place of 7 in 378 = Tens

Place of 3 in 378 = Hundred

Now we can write this number as ( 300 + 70 + 8 )

( 300 + 70 + 8 ) × 6 = (300) × 6 + 70 × 6 + 8 × 6

                                = 1800 + 420 + 48

                                = 2268

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.
