Need some help! Graph the equations y=3x-5 and x+3y=6 on the same xy-plane. What is significant about these two lines? (Explain
adell [148]
To solve this, we must first put both lines in Slope Intercept Form (y=mx+b where m is the slope and b is the y-intercept).

y=3x-5 is already in SIF, so we only need to work on the other one.

 x+3y=6
-x       -x
 3y=-x+6
 /3      /3
 y=-1/3x+2

Now we have both equations in slope intercept form, so we can start graphing from the y-intercepts and just follow the slopes.

When we do this, we will see that the lines meet at an exactly 90° angle. When a pair of lines does this, it means they are perpendicular.

Below I have attached an image that has both lines graphed so that you may visualize it. The green dots show the slopes, while the highlighted areas show the y-intercepts. Note that the lines intersect at a 90° angle, making them perpendicular.

Tatiana's book has an area of 88 square inches. what are the length and wide measurements of the book​
Vedmedyk [2.9K]
A= l•w

So you can make it in any way! The one I got is 44•4 because

A= l•w
A= 4•22
A= 88

So I guess it depends on the way you want it as long as it equals 88 as long as you length and width are multiplied to make the 88, if you host what I mean!

1. (1 pt) Which is a solution to the equation y=3x+1 ?A. (3, 10) B. (2, 6) C. (1, 5) D. (0, 3)
frozen [14]

Answer:

the easy way to figure this out is to just plug in answers.

start with a,   (10)=3(3)+1

                     10=9+1

                      10=10

this makes this  a true statement

feel free to try the other options but this is your answer

A. (3,10)

Feliz [49]

Answer:

  D.  3

Step-by-step explanation:

For g(x) = |x|, we seem to have ...

  f(x) = 3|x| = 3g(x) = a·g(x)

The value of 'a' is 3.
