Question

Which graph models the equation -3x + 2y = 6? 


What number does it fall on the x axis and y axis

jim766 · Answer

first solve for y,   do you know how to do that?

anonymous · Answer

no

anonymous · Answer

do i add 3 to both sides

jim766 · Answer

-3x + 2y = 6     yes
+3x            +3x
2y = 3x + 6     now what?

jim766 · Answer

what is keeping the y from being alone?

anonymous · Answer

uhmmm. it has 2 in front of it

jim766 · Answer

right....it is  2times y , do the opposite to get rid of it

jim766 · Answer

divide both sides by 2

anonymous · Answer

3x + 3

anonymous · Answer

but on a graph on my x axis will my line cross three and cross the y axis to enter my 2nd quadrant

jim766 · Answer

-3x + 2y = 6     yes
+3x            +3x

2y = 3x + 6     now what?
--    --     --
2      2       2

y = 3/2x + 3

jim766 · Answer

when you divide both sides by 2, you have to divide everything by the 2

jim766 · Answer

y = mx + b
y = 3/2x + 3

anonymous · Answer

oh ok so when i divide 3 by 2 whats the next time after that

jim766 · Answer

6/ 2  = 3

y = mx + b
y = 3/2x + 3      what is the y intercept?

anonymous · Answer

2x i think

anonymous · Answer

NO 3

anonymous · Answer

so itll be 2 on the x axis and cross and fall on the 3 on the y axis if im correct

jim766 · Answer

yes 3 is the y intercept, that is where the line crosses the y axis

set y = to 0 and solve for x to see where it crosses the x axis

-3x + 2y = 6
-3x + 2(0) = 6   solve for x

anonymous · Answer

ok when i multiply and my 2 is gone do i add 3x to both sides or.. 6 im assuming 3 but then i get um 3=6

anonymous · Answer

and now i guess if it is 3=6 i um divide 3 by both sides which leads to the conclusion of 3/6 = 2 right ?

jim766 · Answer

divide both sides by -3     

6/-3   = -2

jim766 · Answer

the line crosses the x axis at -2

anonymous · Answer

thanks jim can you help me with with other problem

anonymous · Answer

A geometric sequence is defined by the recursive formula t1 = 64, tn = 


tn - 1



2

, where n ∈N and n > 1. The sequence is

jim766 · Answer

t1 = 64,  tn = tn -2  , is that right?

anonymous · Answer

i have to find the next 6 terms starting with 64
