Alexandra [31]4 years ago

To give a simple answer

if you consider the equation to be that of a line.
then if the variables cancel out, then the two lines will have the same slope.

two lines with the same slope fall under two categories. Parallel lines, and lines on top of each other

parallel lines have no solutions since the lines never cross each other
lines on top of each other have infinitely many solutions  since they "cross" everywhere on the line

Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1
REY [17]

Answer:

perpendicular

Step-by-step explanation:

3y = x + 4 in slope intercept form y = 1/3x +4/3

3x + y = 1 in slope intercept form y = -3x +1

the slopes are negative reciprocals of each other so they are perpendicular

A box contains 5 blue, 4 red, and 3 yellow marbles. Two marbles are randomly drawn and not replaced. What is the probability of
Nataly_w [17]

Answer:

the answer is 5/33

Step-by-step explanation:

Total marbles = 5 blue + 4 red + 3 yellow = 12

Two marbles are selected, first is blue which gives us :

5/12 --eq 1

Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )

The probability of red gave us :

4/11 --eq 2

Now we multiply eq 1 and 2

5/12 x 4/11 = 5/33

Can anyone help with this??
Kipish [7]

Answer:

y=x+6

Step-by-step explanation:

the co-ordinate points are (-2,4)and (4,10) so <u>y2-y1 </u>

                                                                           x2-x1    

<u>10-4 </u> =6

4-2    =6   which will be 1 as the gradient so you will form an equation

<u>y-10</u> =1 cross multiply the values with one so the answer will be y-10=x-4

x-4  

take -10 to the other side it will be y=x-4+10 hence y= x+6
